<html> Maggie Jusiel, I have just visited the archives after several months and saw your question about keytop dye.  I had a client with an old birdcage with plastic keytops and a couple were missing.  The existing keytops were slightly discolored with age and I tried to figure out how to discolor the replacements to match the originals.  I tried soaking the replacement plastic keytops in some tea overnight.  No luck. Next I poured a small amount of lacquer thinner into a cap and dipped a brown felt-tipped marker into the thinner.  This created a very thin dye which I wiped onto a replacement keytop.  It successfully created a faded appearance, although the color did not match the originals exactly.   So I told her that was the best I could do and sold the job.   Did you have any luck from your own efforts?
