OK I noticed my leadpipe's kinda gucky so.... I cut a piece off of the "Zorbee" washing cloth in the kitchen, maybe 3/4 inch wide by 10 inches, lol wonder when it will be missed? Then took some nice fishing line I have around here, 80lb test lol, the woven kind not monofiliment..... And tied a piece on each side of the doubled-over piece of "Zorbee", just 1/2 inch from the ends. Then went out in the shop and found a couple of small nuts, small enough to go into the leadpipe w/o getting stuck. Tied one on each end of the string. OK so now took that tuning slide off of the trumpet, so I can put this through the leadpipe, and ran it back and forth a couple of times, with the cloth damp, good scrub all up and down, then take out, wash, rinse, do it again.... Now my leadpipe's a lot less gucky! Chamois might work, or that synthetic chamois material too. Pretty cool and not hard to make.
