Nikwax Tech Wash is the market leader; it has been specifically designed and optimised for breathable waterproof fabrics.
Nikwax Tech Wash is a highly effective cleaner. Additionally it will revitalise existing Durable Water Repellency (DWR) and revive breathability. It is the safe way to thoroughly clean your waterproof clothing and equipment.
The NikWax Tech Wash cleans effectively, reviving breathability and water repellency for wet weather clothing and equipment.
Why breathability depends upon water repellency
Breathable waterproof garments are most likely to get sweaty and wet inside when used in damp or wet conditions. If the outer fabric absorbs water, the garment can lose up to 70% of its breathability. Therefore, the Durable Water Repellency (DWR) on the outer fabric of your jacket must be maintained to ensure comfort. Nikwax Tech Wash will revitalise the DWR and therefore breathability of your garment.
Use NikWax Tech Wash when your waterproof clothing and equipment soaks up water
Your waterproof clothing and equipment could be soaking up water because the Durable Water Repellency (DWR) has been compromised by dirt, or because it has been cleaned with a conventional laundry detergent. Dirt attracts water and household detergents leave water attracting (hydrophilic) residues, leading to fabric 'wetting out' in wet or damp conditions.
If your waterproof clothing or equipment is relatively new or recently treated with a Nikwax waterproofer, then cleaning with Nikwax Tech Wash will not only remove contaminants, such as dirt and residues left behind by household detergents, but also revitalise DWR.
