Chrome exhaust tips

[Stewart13]

Can anyone give me some information. The chrome exhaust tips on my 67 jcw f54 are starting to pit due to always being black from what I can only describe as being unused petrol. The car and the exhausts are washed every week. Thanks in advance

Give them a polish with some Autosol or the likes and some wire wool

Once polished (0000 wire wool if necessary) seal with Finish Kare 1000p

I use autosol if the tips are heavily coated in carbon otherwise I use carbon collective lustre and put a coat of am wheel wax on top and lasts quite a while afterwards the tips can be cleaned with just a wet microfibre

Thanks for the replies. Maybe I should have asked the question differently. Can you please tell me why the excess petrol is coming out black and causing this. It is a 2 litre jcw all 4 clubman. It has only done about 4500 miles. Is it running rich ?

In sport the Jcw and S use fuel to make the pops

Normal for some discolouration,but pop up some pics so we can see

Stock maps have always been on the rich side for safety

Yes that's completely normal, not even as black as others I've seen
