All of the auto detailers that I know use Dawn dishwashing liquid to remove all wax buildup before restoring the paint. I'm sure that would work on your denim paint as well. Good luck!
What he said,I just didnt want to say it!! Best advice other than home remedies call a body shop or body shop supply thell have the products to get all the wax off Im sure. When I worked at body shop years ago we used some 3m products to do this just cant remember the names! learned your lesson didnt ya
My denim black Fatboy got waxed, and looks horrible to say the least. Whats the best way/fastest way to strip this stuff off?
I can't help with which would be the best choice to remove the wax ... but I strongly suggest that you find an inconspicuous spot to try before doing the whole bike .... try a cleaner and let it dry, evaluate the results .... then if you're satisfied move on to the rest of the bike .... Good Luck Brother!
