how do you get the white wax off the black (rough) unpainted body peices like the trim around the window/mirrors/vents on hood excetera? I tried a toothbrush with soapy water and fantastic. it looks like its gone until it dries!
Your best bet is avoiding it in the first place by using a clear, non-residue forming wax, I prefer Zaino products, but many other lines have come out that are available in your local car parts store.
I carry a chemical polish by Poorboys that will remove the white residue. I also carry a product called Trim Restorer that works great on black plastic parts. Let me know if you have any questions about the products.
