If dirty glass is a pet peeve for you like it is for me, here's the latest technology for clean windows. I've taken our fantastic micro fiber cloth and woven it even tighter so it grabs on to oils and dirt better. Use these along with our Window Cleaner when cleaning windows, glass and mirrors. Not only will you get cleaner windows with lint-free drying, you'll protect the environment by not throwing away paper drying towels. You get four machine-washable cloths that measure an ideal 11 3/4" by 15 3/4". I made them blue so you don't mix them up with your polish and wax cloths. The Micro Fiber Window Kit includes a 35 ounce bottle of Window Cleaner, a Finest Sprayer, and four Micro Fiber Cloths.
