I recently acquired a mixed set of valve shims for my Lancia Beta and around two-thirds of them had varying degrees of rust. I only paid a tenner for them and knew this was the case, so sorted out the rusty ones and dropped them into citric acid solution in my small ultrasonic machine. After half an hour or so I pulled them out and washed them off. At that point I realised the rust was gone but they were covered with a thin layer of black stuff. I also discovered that this black stuff is quite hard to clean off hands. Ideally I'd like to get the shims to a semi-shiny state and be able to mic them up and then use permanent marker to write down the values on the shims.
Any suggestions as to how to get the black stuff off the shims and to a state where I can use a marker pen on them?
