I believe you are out of luck on this one. You can prevent mold, but once it attacks the record it eats into the vinyl and cannot be repaired.
Removing mold from LPs?
I was hoping you could share your experiences on what products (brand names or DIY) and/or processes have worked the best for you in removing mold from your LPs. I bought a SEALED LP that is 28 years old (that I already have a few copies of) and was all excited to hear a pristine version - just to open it and see it was embedded with what I believe is mold which didn't come off with a good cleaning with Disc Doctor fluid and my VPI 16.5 (and three rinses). It is definitely affecting the sound. Any ideas are appreciated!
