Nikwax is not bragging when they state they’re the No.1 easy to use, safe, high performance cleaner for wet weather clothing and equipment, that’s a fact. Designed for use for Gore-Tex®, eVENT™, and similar technologies Nikwax Tech Wash® revitalizes the DWR, Durable Water Repellency, on the outer fabric. Why? Because if the outer fabric absorbs water, the garment can lose up to 70% of its breathability! You’re more likely to feel wet, sweaty, and sticky inside when the outside is wetting out. Washing jackets in household detergents leaves a hydrophilic residue, what that attracts moisture instead of repelling it, leading to fabric 'wetting out' in wet or damp conditions, just what you don’t want your jacket doing. Regular cleaning will enhance the performance of your gear. With regular cleaning, you should be able to clean your gear 5-6 times with Nikwax Tech Wash before it requires re-waterproofing. When waterproof clothing or gear new cleaning with -will not only remove dirt, sweat and oils that compromise performance but also revitalize the DWR. When your gear fabric no longer beads up and sheds water it is time to re-waterproof the piece with a Nikwax TX Direct® waterpoofer. Keep your jackets in peak condition and they’ll keep you dry and comfortable for seasons to come.
