Dual-Composition Hydrogen Peroxide Cleaner for Outdoor Stains
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning processes are ineffective for removing outdoor stains from various surfaces exposed to the elements, as they often use harsh chemicals, require specific environmental conditions, and are not suitable for consumer use, failing to address the unique challenges of outdoor substrates and stains formed by mildews, molds, algae, and UV exposure.
Innovation Solution
A cleaning product utilizing two separate compositions that react to form oxygen species, with hydrogen peroxide as the oxygen donor and silicates, carbonates, or bicarbonates as the activator, applied together to outdoor surfaces to effectively remove dirt and stains without harming the environment or users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If harsh chemicals are used to remove outdoor stains, then cleaning effectiveness is improved, but safety for consumer use and environmental friendliness deteriorate
Solution Approach 1:
The patent changes the chemical parameters from harsh industrial cleaners to a milder system based on hydrogen peroxide (oxygen donor) combined with silicates, carbonates, or bicarbonates (activators). This parameter change maintains cleaning effectiveness through oxygen species generation while improving safety and environmental compatibility for consumer use.
Solution Approach 2:
The patent employs hydrogen peroxide as an oxygen donor that generates oxygen species when activated by silicates, carbonates, or bicarbonates. This oxidation mechanism effectively removes organic stains from outdoor surfaces while using environmentally friendly chemicals that decompose into water and oxygen, avoiding harsh substances.
2Reliability
If industrial cleaning processes are used for outdoor items, then stain removal capability is improved, but process complexity and environmental conditions required worsen
Solution Approach 1:
The cleaning composition is designed to be self-activating when the oxygen donor and activator are combined. The chemical reaction that generates oxygen species occurs automatically at ambient outdoor temperatures without requiring external heating, soaking, or controlled environmental conditions, simplifying the process for consumer application.
Solution Approach 2:
The patent divides the cleaning system into two separate components - an oxygen donor (hydrogen peroxide) and activators (silicates, carbonates, or bicarbonates). This segmentation allows stable storage of individual components and simple mixing at the point of use, reducing process complexity while maintaining effective stain removal capability.
3Reliability
If high temperatures and submersion are used for cleaning, then cleaning effectiveness is improved, but ease of operation and applicability to large outdoor surfaces worsen
Solution Approach 1:
The patent replaces mechanical cleaning methods that require submersion and high-temperature equipment with a chemical cleaning composition that can be applied directly to large outdoor surfaces. The composition works at ambient temperatures through chemical oxidation, allowing easy application to decks, fences, patios, and other extensive outdoor areas without industrial equipment.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The combination of hydrogen peroxide and activator is more effective than either component alone, safely removing outdoor stains from diverse surfaces without requiring submersion or high temperatures, while being environmentally friendly and easy for consumers to use, with the added benefit of being biodegradable.
Implementation Method 1
The combination of the first and second compositions are more effective at removing dirt and stains than is either of the compositions alone or either of the compositions combined solely with water

AI summary
A product for cleaning a surface includes a combination of a first composition with a second composition. The first composition includes hydrogen peroxide and makes up 94-99.5% of the combination by weight. The second composition includes at least one of a silicate, a carbonate, a bicarbonate and a percarbonate and makes up 0.5-6% of the combination by weight. The first composition and the second composition are stored in separate vessels until combined to form the combination. The combination is applied to the surface after mixing.
