Up here near Rio Rancho it's not uncommon to have the wind blow 30+ MPH, which makes for a nice dust storm, and anyone that has ever used Armor All (Or a variation, BackToBlack, 2001, TireWet, Etc.....) Knows that these leave a nice layer of Grease, the shinier the more it attracts dust. What do you all use to clean off this layer of greasy dirt before applying new tire dressing????
