Shake the bottle and pour 75 ml into the detergent compartment. (If the garment needs to be waterproofed, use a Storm Proofer that fits.) Wash according to the manufacturer's care instructions for the garment.
Technical garments have a membrane and DWR coating that ensures that the garment performs at its highest level and does not absorb water/get wet. DWR performance may decrease due to dirt, sweat, grease, detergent and general use. Dirt and debris accumulates on the surface and in the microscopic pores of the fabric, which can lead to reduced breathability and water repelling. That's why it's important to keep the garment clean to ensure it performs as intended.
Proper cleaning revitalizes the fabric without harming any active DWR treatment. Using ordinary household detergent is not appropriate when it comes to the care of technical outer clothing, as it can damage the DWR treatment of the garment. They contain many compounds that do not favour performance, such as bleach, dyes, enzymes and perfumes.
When a garment is new and only dirty, a simple clean may be sufficient. However, an older garment may require a little more care as it loses its water repellent ability over time, which can easily be restored with the addition of an impregnation.
