I know this isnt much of a "tech" question but...my rear main seal leaked for a little while and got oil all over my y-pipe and a little on the pass side header. Well the oil is basically burnt on there but the ceramic coating underneath looks perfect. I'm planning on selling them but i'd like to clean them up as much as possible first. I was wondering if anybody knew of a good way to get the oil off without hurting the coating?

Thanks
