So question, I have a record that, aside from not being cracked looked as though it's had a pretty rough life. It is grey and looks like it was stored in between two pieces of sandpaper and then squished between two other records. You know the kind I'm talking about. It was so bad I actually didn't want to even wear down a needle playing it except that the music on it was intriguing. So I thought "Now THIS is a record I can try WD40 on". I used a fresh steel needle on my Columbia 710 and it sounded great! At the end I noticed that there was a LOT of buildup on the tip of the needle and when I looked at it under a microscope I found microscopic bits of dust, debris, old needles, all had been picked up by the needle and taken out of the grooves. I've never seen that on a record before. Thinking it was a fluke I tried the second side and got the same result, almost like it flushed a bunch of crap out of the grooves.
Thinking it was just this record I dug through my collection to pull out another rough record. I played it once without WD40 (nothing ended up on the needle after) and then gave it WD40. Now when I say I put WD40 on it I mean I put the TINIEST amount on a paper towel and wiped it around the shellac being careful not to hit the label. Same thing! After 1 play the needle seemed to pull a bunch of debris out of the grooves! I played the record 3 times, it got less each time and the 4th time the needle was clean.
And so my question to the users of WD40 on rough records, have you ever noticed this phenomenon happening on your machines after playing a freshly treated record?
