Iff you can pull them, it would be easy on a bench grinder with a cotton buff wheel. Just remove the gaurd, and install the wheel. Use some white jewlers polish, then some white diamond metal polish. I did mine on the truck. Makes a mess that way. I do have a buffer that I use some. I also use a die grinder from time to time. Here is a pic.You must be registered for see images attach
