If you ever buy used records, you’ve learned that however clean they looked in the store, they sometimes skip or have a little scratch as loud as a gunshot, usually on your favorite song. I’ve used this fix at least five times, and it worked every time, both on skips and loud scratches that run across grooves. (If the scratch runs with the groove, you’re pretty much fucked, as the gentleman in the video points out. ) Using a toothpick is a brililant solution. It can get into a groove just enough to smooth out the edges, but it’s not sharp enough to go deep into the groove and ruin the record. I guess you could ruin it if you pushed hard enough, but gentle pressure fixes the problem.
