I finally have my case all cleaned prepped and painted AND have all my NOS replacement parts ready to assemble back in the case. What do you best recommend to clean the old reusable gears, bearings abd shafts as well as a couple of NOS shafts and gears (with years of shelf dust) on them with?? ALsO do you use any gasket sealer on the gaskets??

Thanks in advance
