Product Description The perfect way to clean your technical outdoor garments - and an important first step in effectively waterproofing your kit Granger\'s Performance Wash is a wash-in formulation designed to carefully clean all of your outdoors and technical clothing. Washing your specialist outdoor garments in regular household detergents can leave them contaminated with various chemical residues. As a result, the technical features your garments possess - properties such as breathability or water-repellency - might become much less effective. Fortunately, Granger\'s Performance Wash has been designed to work with the specialist materials that make up your technical garments, rather than against them. It removes dirt and eliminates odours whilst maintaining breathability and water-repellency. It even cleans at temperatures as low as 30C, so you can be sure your clothing is thoroughly clean whatever wash-cycle you use. Performance Wash is suitable for use on all types of technical clothing, as a replacement detergent for your regular washing, or as the first step in applying water-repellent treatments.
