Hydrogen peroxide has bleaching effect.
Hydrogen peroxide is used as a bleaching agent for cotton fabrics in printing and dyeing industry to reduce the color of dyed dyes. Used to remove iron and other heavy metals when producing metal salts or other compounds. It is also used in electroplating solution, which can remove inorganic impurities and improve the quality of plated parts. It is also used for bleaching wool, raw silk, ivory, pulp and fat. High concentration of hydrogen peroxide can be used as rocket power combustion improver.

Precautions
Hydrogen peroxide itself is nonflammable, but it can react with combustible materials to release a lot of heat and oxygen, causing fire and explosion. Hydrogen peroxide is most stable at pH 3.5 ~ 4.5, easily decomposed in alkaline solution, and can also be decomposed under strong light, especially short-wave radiation. When heated above 1℃, it begins to decompose rapidly. It forms an explosive mixture with many organic substances such as sugar, starch, alcohol and petroleum products, which can explode under the action of impact, heat or electric spark.
when hydrogen peroxide comes into contact with many inorganic compounds or impurities, it will decompose rapidly, leading to explosion, releasing a lot of heat, oxygen and water vapor.
