The only cleaner designed to protect against UV damage and revitalize water repellency of all weatherproof textiles. Easy to apply by hand, non flammable, PFC and aerosol free. Tents and backpacks use synthetic fabrics, such as nylon or polyester, with a thin watertight polyurethane (PU) or elastomeric coating on the inside and a Durable Water Repellent (DWR) coating on the outside. This combination gives great strength and water resistance, combined with light weight, ideal attributes for outdoor equipment. Unfortunately these fabrics are vulnerable to sunlight and in two weeks of continuous exposure, can lose up to half of their strength. Additionally, the inner coating will degrade if it is left damp for long periods. Nikwax Tent & Gear SolarWash cleans the entire fabric, and protects from the effects of both UV and water.
