What do you do when nothing seems to get LP clean?


What do you do when nothing else seems to work? I have scrubbed with disc doctor brushes; used VPI fiber brush; tried multiple washings and nothing seems to get out this visible "gunk". Whatever it is, I've noticed it on a number of used LPs that I've tried to rescue. Its not raised, but just seems to have "attached" itself to the vinyl. Is it mold? I know its hard to know what exactly I'm dealing with without being able to see it, but what do you use as a last resort, when nothing else seems to do the trick?

I asked a friend who's a neurosurgeon if rinsing and vacuuming and drying would remove a microscopic enzyme and he laughed. He started to talk about operating-room procedures in neurosurgery, and touched on biological/weapon contaminant clean-up.

When he was in med.-school, they looked at "clean" surfaces. What we typically think should be "clean" is not really de-contaminated.

In our purpose, the record cleaning platter, brush, and vacuum head are the worst--do you throw them away after each record? With my (non-enzyme) cleaning, this is not too much of an issue, I hope. I know that my VPI used to grow mold spores or something with stuff that I used to use. With what I use now, it doesn't anymore.

Doc's going to get back to me over the weekend.

He did suggest that a guy may need ot be prepared to use plenty of solvent or possibly high heat. Does that mean enough heat to warp, or enough solvent or alcohol to soften the plastic? I don't know.

I can see that if a microscopic enzyme gets lodged or trapped in a scratch in a groove, the stylus might no longer "read" the scratch. It may well get stuck there for a while.

If he says that there's no reason to be concerned with long-term effects of enzymes/plastic, this could maybe be okay, if the enzyme "fills in" or "fixes" the scratch. It seems that used to be one of the unwritten promises of LAST in the '80s. I don't buy records that have a LAST sticker on 'em, though...
