The exhausts on my xfr aren't in bad shape but show signs of previous cleans.

They are a bit scratched and I can see why. There are small solid lumps of carbon deposits dotted over the outside.

The rim and inner is ok but some small dullness and blackening.

What would you recommend to remove the carbon lumps minimising scratching, anything to break it down so I don't have to rub much but won't damage or discolour the exhaust tips.

Then also a decent polish that you could recommend that will polish out the slight scratches?

Thanks
