I have tried to polish the chrome headers of my exhaust, but can`t shift the stains with either Blue Job chrome paste or AutoGlym chrome cleaner, anyone got any ideas how I can get them clean please.
All of these "blue aways" consist of abrasives that when used often, will thin your chrome. Delaying the inevitable is all you are doing....That is why the Japanese opted for double wall pipes........
The blueing of the headers closest to cylinders is considered part of the BMW aesthetic by most - even that it is indicative of riding hard and fast.
This is why the excretion brown headers of the SSteel is offensive to many.
Not sure what BMW was thinking... must be cost or enviro issues as they seem to have perfected the difficult process of chroming SSteel. Anyway the best I have discovered for polishing the chrome headers (and will take the blue off if added to elbow grease is Autosol meal polish. A dremel polishing attachment can be useful if really tarnished.
