Nikwax Tech Wash is the answer for anyone with a breathable waterproof garment that seems to be soaking up water a little easier than they might like. The reason for this happening is likely because your clothing is dirty! Just a little dirt on the fabric is enough to not only attract water to it, but also make it harder to breathe, meaning the water has nowhere to go, making your clothing wet. The problem with washing your waterproof clothing with household laundry detergent is that it leaves a residue on the fabric that also prevents the piece from breathing well. Nikwax Tech Wash is designed to rid the clothing of dirt and residue, as well as help to restore the original DWR coating on the outside of the garment. For newer waterproof clothing that may be a little dirty or is starting to lose some of its waterproof abilities, a good wash using Nikwax Tech Wash can freshen it up and revitalize its performance level.
