I recently bought Red RA's from a member here and they were in decent shape, but I accidentally scratched it with my finger nail while cleaning them with Windex and 409 (rofl). Anyway, is there some kind of a Polyurethane cleaner I can use? Something that can remove the feint scratches and clean up dirt. I emailed RA but no reply.

Thanks.

Edit: I currently have Black ones and I just wipe them off with some 409 and they look fine.
