I was recently looking for a better way to clean the top of the upper wing on the biplanes and came across a mop system made by Aero Cosmetics http://washwax.com/themop.php Not only do I like it, I fell in love with their products. The Wash/Wax works incredible on lightly soiled surfaces. I did our entire cub with the mop system and it looks great!! Also used their belly cleaner http://www.washwax.com/products/Airc...ly%20Wash.html on the exhaust stains on the CCSS gear and it worked better than anything I've tried. The plexi-clean leaves an anti static finish that beads water. We've used these products on everything in the hangar with excellent results. No ties to this company, just enthusiastic about their products
