When the cars were new the exhaust tips must have looked matt silver. Has anyone ever successfully cleaned them and if so what did you use. Seems that not a lot of owners bother - even OPCs display the cars with dirty tips. Don't want to shell out for the replacement chrome ones so that's not an option. Surely there's something out there??? Tried wire wool (gently) - useless.
Where do you live as the kid who does odd jobs here took my old tips into his school and buffed them up on a Buffing machine they have in his Tech Class ! Cost me a tenner and they look like new. I sure he'd do yours as well. Whatever you do DON'T use wire wool.
I got my 993 just over a week ago and, like you, noticed the dirty finish on the exhaust tips. The OPC dealer suggested wire wool to clean them up but I tried T-Cut instead. It worked well but it will take a few more treatments before they're in prime condition again.
They will discolour almost immeadiately it's the nature of the beast , the best you can hope for long term is to polish the outer visible radius regularly and now and then take them off and polish the bronzed remainder with a rotary tool (ie Dremel) and Solvol or similar
