Description
When high-tech fabrics are washed in detergent, a water-attractive residue is left behind, decreasing the garment’s durable water-repellency (DWR). All waterproof, breathable fabrics rely on the DWR to optimize their performance. Nikwax Tech Wash is a non-detergent, biodegradable cleaner that leaves the fabric’s water-repellency intact and doubles the life of the garment’s DWR. It can also be used on Gortex fabric. Easy to apply in the washing machine. Environmentally friendly, Tech Wash is biodegradable, nonflammable, non-hazardous, and does not contain fluorocarbons. 10 fluid ounces.
A key component in maintaining the functionality of your BigPockets jackets is the DWR (durable water-repellency). The DWR causes water to bead up and roll off the garment instead of being absorbed. This minimizes condensation forming within and maximizes breathability. DWR is not permanent. Dirt; smoke residue from campfires, wood stoves, kerosene or propane heaters; and residues from oil, grease, and detergent can mask the DWR. The result is that rain or snow no longer bead-up, a condition known as “wet out.” Wet out leads to temperature reduction, condensation, increased garment weight, and reduced breathability, all of which will create a sensation that the fabric is no longer waterproof. The wearer will feel damp and clammy. Nikwax products are specifically designed to ensure that your Big Pockets jackets and anorak continue to protect you from the elements year after year after year.
