In Reply to: how do you clean your old vintage tube pins? posted by edisonwu on February 23, 2007 at 18:15:03:
Get a small fine wire brush....size of a toothbrush--from a hardware store. Works great. After brushing/scrubbing off any deposits, then spray pins with Deoxit and wipe dry with cotton rag. Presto.

Are there any chemical matter like hydrochloric or sulfuric acid can be used to break down the coated oxide? The problem with acids are they may erode the metal pins at the same time and operating of them are very dangerous. I know some tube dealers decompose oxide by electrolyzing. It may be the best way (both efficient and resultful to refurbish tube pins. Any ideas of these?
