After I made my first 18 inch Winteralus clean with a pressure washer, some brake dust is still left behind, I did not get away well by very strong scrubbing. Sprayed aluminum devil, leave for 3-4 minutes and then use a sponge Racken (and rubber gloves !!) get the dirt off. Rims look almost like new! Unfortunately, some small black dots (probably burned-on brake dust?) Are not so to get away, even if I still have so firmly scrubbed. However, this fall on only upon closer inspection. That's why I give 4/5 stars because the aluminum devil has otherwise done a very good service and will do in the future to continue ;-)
