So I was cleaning an LP the other day and whilst rotating the edge of the aforementioned brush, the rubber edge (not covered by the brush material) rubbed into the vinyl and left what looks like a grease mark. It kind of reminded me of dragging the sole of shoe across a floor and leaving a black streak. However, unlike the shoe mark which is removed easily, I have thus far been unable to remove this from the vinyl.

Here's what I've tried:
Using enzymatic cleaner (osage/audio intellingent #6) and letting it soak and then scrubbing and rinsing. No result. Then I tried my ultrasonic cleaner for about 20 minutes. also no changes. Then I used full strength Disc Doctor record cleaner solution. I let it soak for several minutes, followed by scrubbing and multiple rinses with purified water (used in all rinses). I then tried simply using 91% ISA but this too proved futile. And the mark remains.

Does anyone have any suggestions or proven removal methods that leave the vinyl unharmed? Thankfully, it's a vinyl record that is not irreplaceable and in fact I found a very nice replacement yesterday while record store hopping in St Louis, MO. But I'd love to know if there is a way to get this removed.

Hi Cabalaska,

Your MoFi brush didn't leave anything behind on the record. The black nitrile rubber used in that brush handle is about 60-65 durometer, so it's much harder than then surface chemistry of the record vinyl. If the record plays okay without noise, then you just marred the surface. If it doesn't, then you've deformed to surface of the record.

If you did damage the record it is good you could find a replacement. I did the same type of thing once and we looked at the record in the lab and it was in fact damage. I actually dropped the brush from about five or six inches above the record and grabbed for it while the record was spinning on the RCM and caused the handle to scrape on the moving record.

Happy listening.
 
You're likely to damage the record if you continue trying to remove the mark. Does it play ok?
 
Nice! Thanks Osage for that answer. Very enlightening.
And MarkB, I haven't played the record as I didn't want to introduce any gunk or damage to my stylus.
Thanks!
