All Kleer was invented by a pilot over 25 years ago for cleaning and maintaining plastic aircraft windshields that require absolute clarity. All Kleer is different than most windshield products on the market as it not only cleans dirt, bugs, water spots, and grease but leaves a very fine, slick finish. The finish helps to repel those same items, inhibit fogging and static, and makes it easier to see and to clean the next time. All Kleer contains no wax, ammonia, or abrasives and does not require the use of any water. The non pressurized leak proof 8oz bottle is designed to be carried on board if desired. Simply apply All Kleer with a clean towel to a dry windshield and allow 30-60 seconds for a haze to form. After it has completely dried, wipe off with a clean towel and feel the All Kleer finish. 8 ounce bottle. 1 lbs (0.5Kg) shipping weight.
