The dirt on leather clothes generally includes sweat secretion, various oils, dust pollution and various pigment pollution. Some of them are soluble in water, some are soluble in organic solvents, and some are insoluble in both. There are four general principles of chemical decontamination: (1) emulsification, (2) reduction, (3) oxidation and (4) dissolution. Therefore, the choice of washing methods and detergents should be based on the types of stains. It must be cleaned before painting. Cleaning method refers to directly scrubbing the dirt on the leather surface with clean cotton cloth or cotton ball dipped in detergent. Commonly used cleaning agents include (1) mixed solution of ammonia, alcohol and water, (2) some weakly alkaline cleaning agents and (3) some special leather cleaning agents. For some leather clothes that are not too dirty, you can use (1)(2) cleaning materials, which are cheap and easy to get. For some dirty clothes or light-colored leather clothes, it is best to choose some special cleaning agents for leather clothes with better effects. When cleaning, clean it thoroughly. Especially for neckline, cuffs, sleeves and other particularly dirty places, we should focus on handling them, and then properly color them to cover them. Otherwise, it will be difficult to cover the dirty background, especially the light-colored leather clothes. If the white fur turns yellow, you can mix two glasses of water with 1 spoon of hydrogen peroxide, then gently brush the fur with a brush dipped in the solution, and finally wet it with water once to make the fur white.
