I have used the type of sand paper that is made of (mounted on) cloth (can't think of the name of it and it's used for polishing) with good results. It has gotten rid of the start up "rustle" on some old signal tubes. I am leary of using it on plated pins though as I went through the gold on one once. I lost my sheet so have to replace it to clean up a couple batches of NOS tubes that I have since received. I now use Kontak on all the tube sockets and pins and the grunge that it lifts (that alcohal did not get rid of) is visible as the results are audible. This is the first place that I tried it out and the improvement motivated me to clean the rest of the connections in the system.
