What are the things to use to remove the black oxidation from the exhaust tip.
Also, there were some coolant that was accidentally sprayed onto the header, is there a way to remove the stain marks?

Would using rubber alcohol, chrome polish, brake cleaner or wax cleaner help?

 

polish

 

i hear eagle 1 mag and aluminium wheel polish works really well. can be found at canadian tire and it can also remove the blueish colour the stainless steel header turns into after a while.........
