Description

Technical Field

[0001] This invention relates to the field of automotive cleaning technology, and in particular to a waterless car washing method. Background Technology

[0002] Traditional car washing methods mainly involve high-pressure water gun rinsing, foam spraying, and sponge scrubbing. Water is an indispensable core medium throughout the entire cleaning process—whether it's the high-pressure water gun rinsing, foam dilution, or the post-wash rinsing, all rely on the participation of a large amount of clean water.

[0003] More importantly, water as a cleaning medium has inherent defects. After a vehicle has been driven, a large amount of mud and sand particles adhere to the paint surface. When the high-speed water jet from the high-pressure water gun impacts the vehicle body, it pushes the mud and sand particles across the paint surface at high speed, causing fine scratches. At the same time, if the water gun pressure is unstable or the angle of operation is incorrect, the high-pressure water jet itself can also cause impact damage to the paint surface. Summary of the Invention

[0004] In order to solve the above-mentioned technical problems, the present invention provides a waterless car washing method.

[0005] The technical solution of this invention is implemented as follows: A waterless car washing method includes the following steps: S1. Eliminate the electrostatic adsorption layer on the car body by using an electrostatic brush; S2. Clean the mudguards with a cleaning brush; S3. Spray the essence onto the paint surface of the vehicle body and wipe it in one direction using the first wiping tool; S4. Spray the essence onto the glass surface, and then wipe it wet and dry using the second wiping tool. S5. Spray the essence onto the wheel area and wipe the wheel area with the third wiping tool.

[0006] Further, step S3 specifically includes: diluting the essence according to a first preset ratio to prepare a first cleaning solution; spraying the first cleaning solution onto the exterior paint surface of the vehicle body using a spraying tool in a first spraying sequence; allowing it to stand after spraying to physically separate the stains from the paint surface and form a lubricating protective layer; then using the first wiping tool to wipe the exterior paint surface of the vehicle body in a first wiping sequence, the first wiping sequence being consistent with the first spraying sequence.

[0007] Furthermore, the first spraying sequence is: roof, hood, grille (i.e., the front bumper air intake grille area), right side of the vehicle, rear of the vehicle, and left side of the vehicle.

[0008] Further, step S4 specifically includes: diluting the essence according to a second preset ratio to prepare a second cleaning solution, spraying the second cleaning solution onto the glass surface using a spraying tool in a second spraying sequence; and then wiping the glass surface using the second wiping tool in a second wiping sequence, wherein the second wiping sequence is consistent with the second spraying sequence.

[0009] Furthermore, the second spraying sequence is: windshield, right side window, rear window, left side window.

[0010] Further, step S5 specifically includes: diluting the essence according to a third preset ratio to prepare a third cleaning solution, spraying the third cleaning solution onto the wheel area using a spraying tool in a third spraying sequence; and then wiping the wheel area using a third wiping tool in a third wiping sequence, the third wiping sequence being consistent with the third spraying sequence.

[0011] Furthermore, step S5 also includes a polishing step: mixing tire anti-aging agent into the essence to obtain a first polishing liquid, and using the first polishing liquid with a fourth wiping tool to wipe the wheel area in the third wiping sequence.

[0012] Furthermore, it also includes the following steps: S6. Dilute the essence according to the fourth preset ratio to prepare a polishing liquid; first spray the polishing liquid onto the black side of the sanding cloth, then evenly spray the polishing liquid onto the paint surface of the vehicle body, and use the sanding cloth to polish according to the polishing sequence. S7. Spray the essence onto the paint surface of the vehicle body and wipe it with the fifth wiping tool; S8. Wrap a damp towel around a scraper tool and scrape away dust from the gaps in the vehicle.

[0013] Further, step S7 specifically includes: A waxing and polishing agent is mixed into the essence to obtain a second polishing liquid. The second polishing liquid is sprayed onto the paint surface of the vehicle body in the first spraying sequence using a spraying tool. Then, the fifth wiping tool is used to wipe the surface in the first wiping sequence.

[0014] Furthermore, step S8 also includes: Apply the essence to a brush and clean the crevices of the vehicle.

[0015] Compared with the prior art, the present invention has the following advantages: This invention eliminates the need for high-pressure water guns and large amounts of water throughout the entire process. It uses an essence as the cleaning medium, and the suspending agent contained in the essence physically separates the stains from the paint surface. Combined with wiping tools, the stains are removed, achieving thorough cleaning under waterless conditions and eliminating the consumption of water resources in the car washing process. This invention eliminates static electricity on the car body using an electrostatic brush, reducing dust adsorption. The mudguards are pre-cleaned with a cleaning brush to remove large pieces of mud and sand, preventing scratches on the paint surface from grit during subsequent wiping. After spraying the paint surface with an essence, one-way wiping is used to avoid secondary scratches that may be caused by repeated wiping. There is no high-pressure water jet impacting the paint surface during the entire operation, avoiding scratches and damage to the paint surface caused by water jet impact. This invention uses first, second, and third wiping tools to clean three different parts—paint, glass, and wheels—separately. Each wiping tool is used independently for its purpose and is not mixed with others, effectively preventing cross-transfer of contaminants between different parts. In particular, it avoids bringing grit from the wheel and mudguard areas into the paint, further ensuring the safety of the paint. Attached Figure Description

[0016] Figure 1 This is a flowchart illustrating the steps of a waterless car washing method according to the present invention. Detailed Implementation

[0017] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0018] like Figure 1 As shown, this embodiment provides a waterless car washing method, including the following steps: S1. Eliminate the electrostatic adsorption layer on the car body by using an electrostatic brush; Specifically, use an electrostatic wool brush to gently sweep the surface of the car body in one direction from the roof to the body to eliminate the electrostatic adsorption layer on the car body and remove surface dust. The optimal operation time for a single area is 30 seconds. Sweep until there is no visible dust on the car body surface and no electrostatic adsorption can be felt when touched.

[0019] S2. Clean the mudguards with a cleaning brush; Specifically, use a cleaning brush to clean from the mudguard to the top of the tire. The optimal cleaning time for each area is 20 seconds. During the cleaning process, the mud and sand brushed off can be collected in real time through the vehicle's storage box or other storage containers (such as plastic boxes) to prevent the mud and sand from scattering and causing secondary pollution. Clean until there is no accumulated mud and sand or stubborn stains left on the mudguard and the top of the tire.

[0020] S3. Spray the essence onto the paint surface of the vehicle body and wipe it in one direction using the first wiping tool; In this embodiment, the serum is composed of the following ingredients: Sodium dodecylbenzenesulfonate 15%; 5% water-based montmorillonite wax, which has protective and polishing properties; 20% dimethyl silicone oil for surface polishing; 3% oleic acid used in the mixture; 15% glycerol for surface wetting and heat preservation; 5% fatty alcohol polyoxyethylene ether as a surfactant; 3% emulsifier; 32.5% ionized water; Waterproofing agent 1.5% used to protect paint film.

[0021] Step S3 specifically includes: diluting the essence according to a first preset ratio to prepare a first cleaning solution; spraying the first cleaning solution onto the exterior paint surface of the vehicle body using a spraying tool in a first spraying sequence; allowing it to stand after spraying to physically separate the stains from the paint surface and form a lubricating protective layer; and then wiping the exterior paint surface of the vehicle body using the first wiping tool (such as a towel) in a first wiping sequence, the first wiping sequence being consistent with the first spraying sequence. Specifically, the first preset ratio is a volume ratio of essence to water of 1:5000 to 1:20000, preferably 1:10000; in some embodiments, the essence is mixed with carnauba wax before dilution, and the mixing ratio is carnauba wax: essence base = 1:20 to 1:100 (mass ratio). Since carnauba wax is a high-melting-point solid wax (melting point 82-86℃), it is insoluble in room-temperature liquid essence. It needs to be pre-treated in the following way before being mixed with the essence base: heat the carnauba wax to 90-95℃ to melt it, add the emulsifier component (3% of the total mass of the essence base) and oleic acid component (3% of the total mass of the essence base) from the essence base, and shear it at 800-1500 rpm for 15-30 minutes at 60-80℃ to form an oil-in-water wax emulsion. After cooling to room temperature, add the remaining components of the essence base and stir evenly. Carnauba wax, as an independent care component, is mixed with the essence base before being sprayed onto the car paint surface. The surfactants in the essence base have an auxiliary dispersing effect on the carnauba wax particles, while oleic acid and emulsifiers work together to stabilize the emulsion state of the mixture, ensuring that the mixture remains uniform during operation.

[0022] After mixing the first cleaning solution, use a spraying tool to spray the first cleaning solution onto the exterior paint surface of the vehicle body in the first spraying sequence. After spraying, let it stand for 5-30 seconds. When wiping, wipe in one direction, without going back and forth or making circles. The whole process takes 5-6 minutes. Wipe until the paint surface is shiny, free of water stains, and free of cleaning solution residue. In this embodiment, the spraying tool can be a hand-operated spray bottle. The first spraying tool is used for paint cleaning (step S3) and waxing and polishing (step S7), the second spraying tool is used for glass cleaning (step S4), and the third spraying tool is used for wheel hub cleaning (step S5). Each spraying tool is used according to its purpose and must not be mixed to prevent brake dust in the wheel hub area from contaminating the paint surface through the spray nozzle.

[0023] The first spraying sequence is: roof, hood, front grille (i.e., the front bumper air intake grille area), right side of the vehicle, rear of the vehicle, and left side of the vehicle.

[0024] S4. Spray the essence onto the glass surface, and then wipe it wet and dry using the second wiping tool. Step S4 specifically includes: diluting the essence according to a second preset ratio to prepare a second cleaning solution, spraying the second cleaning solution onto the glass surface using a spraying tool in a second spraying sequence; and then wiping the glass surface using a second wiping tool (such as a towel) in a second wiping sequence, the second wiping sequence being consistent with the second spraying sequence.

[0025] Specifically, the second preset ratio is the volume ratio of essence to water of 1:2500 to 1:10000, preferably 1:5000; after mixing the second cleaning solution, the second cleaning solution is sprayed onto the glass surface in the second spraying sequence using a spraying tool, and then the second wiping tool is used to wipe first with wet and then with dry to form a water-repellent protective film on the glass surface. The total time for this step is 5-6 minutes, and the glass is wiped until it is clear, without watermarks or oil film residue. The second spraying sequence is: windshield, right side window, rear window, left side window.

[0026] S5. Spray the essence onto the wheel area and wipe the wheel area with the third wiping tool; Step S5 specifically includes: diluting the essence according to a third preset ratio to prepare a third cleaning solution, and spraying the third cleaning solution onto the wheel area using a spraying tool in a third spraying sequence; then using a third wiping tool (such as a towel) to wipe the wheel area in a third wiping sequence, the third wiping sequence being consistent with the third spraying sequence.

[0027] Specifically, the third preset ratio is the volume ratio of essence to water of 1:1000 to 1:5000, preferably 1:2000. After mixing the third cleaning solution, the third cleaning solution is sprayed onto the wheel area using a spraying tool in the third spraying sequence. After spraying, let it stand for 10-20 seconds, and then use the third wiping tool to wipe the wheel in the order of tire rim and tire inner frame. The wiping and cleaning time for a single part is 2-3 minutes. Before cleaning, the third wiping tool should be shaken clean to avoid scratching the rim with mud and sand.

[0028] In this embodiment, step S5 further includes a polishing step: mixing tire anti-aging agent into the essence to obtain a first polishing liquid, and using the first polishing liquid with a fourth wiping tool to wipe the wheel area according to the third wiping sequence; Specifically, pour the first polishing liquid, which is a mixture of essence and tire anti-aging agent, onto the fourth wiping tool (such as a sponge pad). Apply it only to the rubber surface of the tire sidewall, avoiding contact with the metal surface of the wheel rim. Apply it evenly along the circumference of the tire. The polishing time is 1-2 minutes, until the tire surface has a natural shine. In this embodiment, the anti-tire aging agent may be composed of the following components by weight percentage: 20% dimethyl silicone oil, 5% carnauba wax, 2% antioxidant 6PPD, 1% UV absorber, 4% fatty alcohol polyoxyethylene ether, 8% isopropanol, and the balance being deionized water. Antioxidant 6PPD (N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine) is used for ozone and thermo-oxidative aging resistance; UV absorber is used to absorb UV rays and reduce photoaging; dimethyl silicone oil and carnauba wax are combined as film-forming and brightening components; fatty alcohol polyoxyethylene ether is used for emulsification and system stabilization; isopropanol is used to promote penetration and adjust viscosity; and deionized water is used as a solvent carrier. The volume ratio of the essence to the anti-tire aging agent is 2:1.

[0029] S6. Dilute the essence according to the fourth preset ratio to prepare a polishing liquid; first spray the polishing liquid onto the black side of the sanding cloth, then evenly spray the polishing liquid onto the paint surface of the vehicle body, and use the sanding cloth to polish according to the polishing sequence. Specifically, the fourth preset ratio is the volume ratio of essence to water of 1:2500 to 1:10000, preferably 1:5000; the sanding cloth is a consumable, and excessively concentrated essence will accelerate the dissolution and aging of the volcanic mud component. The surfactants and additives in the essence have a certain corrosive effect on the volcanic mud component in the sanding cloth. Excessive concentration will shorten the service life of the sanding cloth, and may even cause volcanic mud particles to fall off and adhere to the paint surface during the sanding process. The core of mud exfoliation lies in the physical abrasive action of volcanic mud particles, while the serum mainly provides lubrication rather than relying on the chemical cleaning power of the serum itself. Shaving involves reciprocating friction between the sanding cloth and the paint surface, requiring sufficient lubrication to prevent scratches. However, since the volcanic clay component in the sanding cloth is sensitive to organic solvents, the surfactants and additives in high-concentration serums may accelerate the wear of the sanding cloth. Therefore, the concentration of serum required for sanding should be moderate, providing sufficient lubrication while avoiding excessive erosion of the sanding cloth.

[0030] Spray the polishing liquid onto the black side of the sanding cloth to fully wet it. Then, spray the polishing liquid evenly onto the paint surface of the vehicle body to keep the paint surface moist. Following the polishing sequence, use the sanding cloth to repeatedly wipe and polish the paint surface of the vehicle body until the paint surface feels smooth. After polishing, use a wiping tool to wipe away any remaining moisture from the paint surface. Before polishing, check if the black side of the sanding cloth has any adhering sand particles or signs of aging and hardening. Observe the sanding cloth against the light; if obvious sand particles are embedded in the black side or the surface has hardened and turned white, the sanding cloth should be replaced with a new one. Only after confirming that the sanding cloth is in good condition can subsequent operations be carried out.

[0031] S7. Spray the essence onto the paint surface of the vehicle body and wipe it with the fifth wiping tool; Step S7 specifically includes: A waxing and polishing agent is mixed into the essence to obtain a second polishing liquid. The second polishing liquid is sprayed onto the paint surface of the vehicle body in the first spraying sequence using a spraying tool. Then, the fifth wiping tool (such as a towel) is used to wipe the surface in the first wiping sequence. Specifically, a waxing and polishing agent is mixed into the essence to obtain a second polishing liquid, wherein the volume ratio of the essence to the waxing and polishing agent is 1:2 to 2:1, preferably 1:1; In this embodiment, the waxing and polishing agent is composed of the following components by weight percentage: 8% carnauba wax, 15% dimethyl silicone oil, 25% No. 200 solvent oil, 5% fatty alcohol polyoxyethylene ether, 3% Span-80, 2% Tween-80, 10% isopropanol, and the balance being deionized water. Brazilian carnauba wax, a natural hard wax, provides high gloss and a dense protective film; dimethyl silicone oil gives the paint a smooth feel and enhances its shine; No. 200 solvent oil is used to dissolve the wax components, regulate the evaporation rate, and ensure even spread of the wax film; fatty alcohol polyoxyethylene ether, Span-80, and Tween-80 form a composite emulsion system to stabilize the oil and water phases, ensuring that the waxing polish does not separate when mixed with the essence; isopropyl alcohol acts as a co-solvent and penetrant, promoting even spread and rapid drying of the wax on the paint surface; and deionized water serves as a solvent carrier.

[0032] The second polishing liquid is sprayed onto the exterior paint surface of the vehicle body in the first spraying sequence using a spraying tool. The spraying distance is 15cm~20cm, and the liquid is sprayed evenly in an atomized state. Then, using the fifth wiping tool, wipe in the same order as the first wiping step, using a circular wiping method; continue until the paint surface has improved gloss and feels smooth.

[0033] The essence contains dimethyl silicone oil (20%) and water-based montmorillonite wax (5%), which have polishing and protective functions. After adding the wax polishing agent, the wax components in the wax polishing agent and the silicone oil and wax in the essence form a synergistic effect. The surfactants (sodium dodecylbenzene sulfonate and fatty alcohol polyoxyethylene ether) in the essence have an auxiliary dispersing effect on the wax components in the wax polishing agent. Oleic acid and emulsifier can work together to stabilize the emulsion state of the mixture, ensuring that the mixture remains uniform during spraying and wiping, so that the wax forms a denser and more uniform protective film on the paint surface.

[0034] S8. Wrap a damp towel around a scraper tool and scrape away dust from the gaps in the vehicle.

[0035] Step S8 further includes: Apply the essence to a brush and clean the gaps in the vehicle. Specifically, use a scraper wrapped with a damp towel to scrape away dust from the crevices; Use a brush tool and serum to clean the details such as car logos and text until there is no dust in the crevices and no stains left in the details; This embodiment also includes: Use a vacuum cleaner to vacuum the floor mats and the bottom of the seats for 8-10 minutes; dilute the essence according to the second preset ratio to prepare a cleaning solution (the second preset ratio is the volume ratio of essence to water of 1:2500~1:10000, preferably 1:5000), and spray it on the center console, gear shift lever, seats, door frames and inner doors, trunk, engine compartment surface, etc. Wipe with a towel in sections to avoid water stains seeping into the interior; the total time for this process is 20 minutes and 20 seconds, cleaning until the interior surface is free of dust, stains, and watermarks.

[0036] The cleaning method for the engine compartment surface is as follows: open the hood, wipe off the surface dust with a towel, dry it with a towel, and add windshield washer fluid as required by the car owner.

[0037] According to the pre-set technical inspection checklist, the paint, glass, wheels, and interior are inspected item by item to confirm compliance with cleaning quality standards, which include: Paint finish: glossy and free of scratches, mud, fingerprints, dirt, water stains, and wax stains; clean details such as car logo, license plate, chrome strips, headlights, side skirts, and crevices; Glass: Clear and free of oil film, mud, fingerprints, dirt, and water stains; cleans windshield wipers and weatherstripping; Wheel hubs: Clean and free of stains, mud, fingerprints, dirt, and water stains; screw holes and mudguard edges are clean; Indoors: Clean and odorless, free of dust and sand; air conditioning vents, center console, door footstools, and ashtrays are clean.

[0038] When there are glue stains or asphalt on the paint surface, mix the essence and glue remover at a volume ratio of 1:1 to obtain a mixture (the essence and glue remover are mixed directly in undiluted form without dilution before mixing), spray it on the stain, let it stand for 30 seconds, and then wipe it off with a purple towel. If the glue stain or asphalt layer is thick, after the first spray and wipe, repeat the spraying and let it stand for 60 seconds before wiping again until it is completely removed. Then, spray the essence diluted in the first preset ratio (1:5000~1:20000) on the area that was in contact with the glue remover, and then wipe it clean with a towel to remove the glue remover residue. During operation, avoid leaving the mixture on the surface of plastic parts and rubber waterproof strips to prevent whitening and damage. The adhesive remover can be composed of the following components by weight percentage: 12% D-limonene, 10% isoalkanes, 6% fatty alcohol polyoxyethylene ether, 4% sodium dodecylbenzenesulfonate, 5% isopropanol, 3% emulsifier, and the balance being deionized water. D-limonene, as a natural organic solvent, dissolves adhesive stains and asphalt based on the principle of "like dissolves like"; isoalkanes, as an auxiliary solvent, enhance the dissolving and penetrating ability of stubborn adhesive stains and asphalt; fatty alcohol polyoxyethylene ether, as a nonionic surfactant, reduces surface tension and promotes wetting and emulsification; sodium dodecylbenzenesulfonate, as an anionic surfactant, assists in cleaning and emulsification; isopropanol, as a co-solvent and penetrant, promotes the penetration of active ingredients into the stain; the emulsifier stabilizes the system, ensuring that the dissolved stains emulsify and disperse upon contact with water, making them easy to rinse and leaving no residue; and deionized water serves as the solvent carrier.

[0039] When there are stubborn stains or oxidation layers on the paint surface, after the paint surface is cleaned, mix the essence and the deep cleaning agent at a volume ratio of 1:1 to obtain a cleaning mixture. The deep cleaning agent is composed of the following components by weight percentage: 18% sodium dodecylbenzenesulfonate, 8% fatty alcohol polyoxyethylene ether, 5% oleic acid, 10% glycerol, 0.5% carbomer, 0.3% triethanolamine, and the balance being deionized water. Sodium dodecylbenzenesulfonate and fatty alcohol polyoxyethylene ether are combined as surfactants to emulsify and disperse stubborn stains; oleic acid acts as an auxiliary emulsifier and lubricant to reduce wiping resistance; glycerol acts as a wetting and moisturizing agent to prolong the contact time of the cleaning mixture on the paint surface; carbomer acts as a thickening and suspending agent to increase the residence time of the cleaning mixture on vertical paint surfaces and prevent dripping; triethanolamine acts as a neutralizing agent to adjust carbomer to neutral and simultaneously adjust the pH of the mixture to 7.0 ± 0.5; and deionized water acts as a solvent carrier.

[0040] Apply evenly to the surface to be treated, use a waxing sponge to wipe away dirt in a circular motion, and then wipe away any residue with a towel; avoid contact with plastic parts during the process, and wipe clean immediately if accidentally spilled.

[0041] It should be noted that in rainy weather, high humidity environments (relative humidity > 80%), or temperatures below 10℃, the wax and silicone oil components in the serum will form a film more slowly, and the settling time after spraying onto the paint surface needs to be appropriately extended. Specifically: the settling time in step S3 is extended from 5-30 seconds to 30-60 seconds; in step S7, the wiping time is adjusted from immediately spraying and wiping to waiting about 3-5 minutes after spraying, until the solvent in the second polishing liquid has partially evaporated and the wax film is semi-dry, before wiping in a circular motion to ensure that the wax fully adheres to the paint surface; if there are water droplets remaining on the paint surface, the moisture must be absorbed with a blue towel before spraying.

[0042] In this embodiment, after wiping, all sprayed liquids are collected by the wiping tool along with the tool itself, and are not discharged into the ground or sewers. After the service is completed, the waste liquid is squeezed into a dedicated waste liquid collection container and handed over to a qualified waste disposal organization for unified treatment. The specific embodiments of the invention have been described in detail above, but these are merely examples. The invention is not limited to the specific embodiments described above. Those skilled in the art should understand that the embodiments and descriptions in the specification are only illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
