i took some time and spent the better part of a day cleaning the wheels up on my 1993 Dodge dually, they are 16x6 Alcoa 8 holes with the rear inners being factory steel wheels.....I painted my rear hubs and wheel mounting surfaces on the steel wheels black so the next time i took the wheels off they would come off easier, first i cleaned them with soap and water then used Nevr-Dull to get the remaining dirt and crud off, then i did them 3 times each with Mother Wheel Polish that comes in the little red can......the wheels look 10x's better than they did when i started, i could tell they hadn't been taken care of that well but being Alcoa's they hold up to the elements pretty well.....here are the pictures.....

 

lookin good..
