Hi guys, just wodering what cleaning agents I can use, to clean a set of 4AG-ZE pistons. I normally use a household oven cleaner to soften and remove the carbon, then wire wheel the pistons.
I will not use the oven cleaner, just in case it reacts with the ceramic coating.
I am also reluctant to use the wire wheel on the ceramic coating, just in case it removes the coating.
Any clues on what to use, would be greatly appreciated.
