PNEUMATIC DE-ICING BOOT CLEANER Boot Klean™ is a highly sophisticated addition to Corrosion Technologies' Aviation line of aircraft maintenance and detailing products. Boot Klean cleans rubber de-ice boots and removes old sealants quickly and easily. Simply apply the product with a scrub sponge, allow the product to penetrate for 2-3 minutes, agitate with the scrub sponge and rinse. Once cleaned, the boots will be flat black. Follow up cleaning your boots with a treatment of Corrosion Technologies' Boot Sealant for a long-lasting, glossy finish that protects your de-icing from fading.
