What is the best way to restore these exhauts

[MagnusXII]

Im looking for some product which can help me to clean my exhauts. Any advise? I post some pic

WD40 to soak the oil/grease crud off and then Nevr-Dull wadding polishing cleaner. Takes some elbow grease but the results are worth it.

You are going to need some rubbing compound and 0000 steel wool first.

Technically chrome does not rust, the rust you see is from the carbon steel underneath, when the protecting chrome plating becomes damaged or scratched the steel below starts to rust.
You will never get it back as new (without stripping the old chrome and re-chroming), but you can improve the look many times by removing the rust by polishing.
I’m using a polishing machine and an angle grinder with variable speed, with different polishing discs and different polishing compounds.
