The No.1 easy to use, safe, high performance cleaner for wet weather clothing and equipment. Cleans effectively, reviving breathability and water repellency. 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. Use neat Tech Wash® and a sponge, or soft nylon brush, to treat stubborn stains before washing. Remove all non-washable parts. Shake well before use. Follow care label instructions. Do not use detergents. Remove all detergent build up from the detergent dispenser. Place item(s) in washing machine (maximum 2 items). Use 150ml in medium/hard water* areas and 100ml in soft water areas for 1-2 items. Wash according to care label.
