I stopped at Advance Auto Parts and saved eight dollars on dent pullers by going down the street to AutoZone. With tax, two pullers were 10.75. I told my wife I wanted some microfiber dish towels and she said she needed some anyway, so I got the solid colors and she took the stripes. That was three bucks for my half. I found a three inch China Bristle Brush at Wal Mart for 1.34. Dish soap we already have. I figured it's worth a try for fifteen bucks to see how clean I can get a dirty record. I even bought a kind of roached copy of Neil Young's Decade for fifty cents specifically for this test. It was just too noisy to listen to, and I knew there was no way I could ever play it all the way through in the condition it was in.
I cleaned off the dent pullers, because they seemed a little greasy from manufacturing, and man, they stick really well. I did it pretty much like the OP, and had all kinds of foamy bubbles going. I dried them gently with my microfiber towels and let them air dry a little while. They sound great and they look great, too. It's amazing how many smudges look like a scratch, but they're gone now and the records have gone from a less than good grade to Very Good. You should see how a Very Good record comes out!
I've paid to clean a few records at a few shops here on occasion, and for the cost of cleaning two or three these days, I did a better job myself, without the amazing static buildup of the glue method (not to mention a lot less mess). I always kind of wanted an RCM, but I don't see that happening. I'll spend that money on more records.
Thanks for the awesome tip!
