Description

Technical Field

[0001] The invention relates to the technical field of cleaning wet wipes, in particular to a cleaning wet wipe. Background Art

[0002] Cleaning wipes are a convenient and efficient cleaning product, widely used in homes, offices, cars, public places and other scenarios. Cleaning wipes are usually made of soft materials, will not cause friction damage to the skin, and are more comfortable to use. Cleaning wipes are available in two forms: independent packaging and pull-out packaging. They are easy to carry and can be used anytime and anywhere. Cleaning wipes contain special detergents that can effectively remove dirt, bacteria, viruses and other harmful substances on the skin surface, as well as stains and oil stains on the surface of objects. In addition to cleaning the skin, cleaning wipes can also be used to clean homes, offices, car interiors and other scenarios.

[0003] At present, in the prior art, cleaning wipes are not effective in removing stains, oil stains and bacteria, and cannot completely remove stubborn stains or deep dirt. The sterilization effect is not ideal and cannot effectively kill specific types of bacteria and viruses. When using existing wet wipes, multiple wipes are required to achieve the ideal cleaning effect, which reduces the use efficiency. In view of this, we propose a cleaning wet wipe.
