Economical easy to use & safe for the environment Granger's 2 in 1 Cleans & Waterproofs washes & restores durable water repellency (DWR) to your favorite technical outerwear. In one easy treatment Granger's 2 in 1 cleans water attracting grit & oil from your garment while also applying a highly effective water repellent barrier that also repels oil & stains. Granger's 2 in 1 Cleans & Waterproofs does not reduce the breathability of Gore-Tex® or other high-end waterproof & breathable garments nor does it change the look or feel of your favorite ski jacket or backpacking rain shell. Granger's 2 in 1 is great for mid-season tune-ups or times when you are in a rush but for that once-a-year overhaul Granger's recommends their G-Wash Cleaner & Wash-in Waterproofing for Synthetic Fabrics.
