The Aero Scrubber is a soft, non-scratching, long-lasting, reusable scrubber pad. Use with Wash Wax ALL to help remove bugs from leading edges or use with Wash Wax ALL (Degreaser) or Belly Wash on tough cleaning jobs such as aircraft bellies, engine areas, wheels and tires. TIP: Spray Wash Wax ALL on bugs and let soak for 10-15 min. then respray and wipe off. This will make bug removal super easy!
