Washing products include towels, soaps, soaps, baths, shampoos, washing powders and other products. Mainly used for cleaning and wiping after the worker finishes work.

Detail Below

Towels are the wiping supplies after the workers work under the mine.
• Soft fabric, no allergic reaction
• Good water absorption
• Easy to use

Towels are the wiping supplies after the workers work under the mine. Coal miners work in wet underground for a long time, and the surface of the skin will adhere to a large amount of coal dust and debris floating in the mine. The special nature of the work site makes the skin surface easily adhere to various oil stains at the same time, and needs to be cleaned in time.
• Towels are the wipes for workers after work.
• Soap can not only remove stains but also cleanse and skin care.
• Bath, specially designed for coal miners to clean the skin.
• Shampoo, clean hair and hair care products.
• Washing powder to remove coal mine stains from clothing.
