The liquid laundry detergent Apparel Wash is used for the care of waterproof clothing and membranes. Technical garments have a membrane with a DWR coating (Gore-Tex, Omni-Tech, etc.) that ensures the garment performs maximum breathability and does not absorb water during outdoor activities. The performance of DWR can be reduced by dirt and sweat, as residues that accumulate on the surface and in the tiny pores of the fabric block breathability and destroy its water-repellent property. Therefore, keeping the garment clean ensures it functions as it should. Also, using regular general-purpose detergent for washing them weakens the performance of DWR, as it contains many compounds (bleaches, enzymes, fragrances, etc.).
