Don't take your favorite performance hiking and climbing outerwear to the cleaners--especially if you value your waterproof finish. Granger's G-Wash Spray Cleaner is a biodegradable formula specifically developed to clean without removing water repellant finishes or blocking porous shell fabric. This spray on/wipe off application is excellent for cleaning your outdoor gear exactly where it needs it most, without the use of any chemical whiteners, UV brighteners or perfumes.
