Cheap Oven Cleaner removes anodizing on aluminum parts, wash with water afterwards and polish to a shiny finish, no more blue & red fittings that don't match your car that doesn't have any red & blue.

Oh yeah, don't let a cheap creeper seat loose its bearing from a wheel while working on a billet steering column, causes you to ruin the column trying to figure out how to "reinstall them" in the column they didn't come out of!
