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?

Yes, Stewart, read the ENTIRE thread. Then, if you have any of the same questions that I had, maybe YOU can get them answered. I couldn't.

Some of these ingredients, e.g., fragrances and fabric softeners, work best when they don't wash off easily. This is a problem for vinyl.

I agree. Same goes for certain enzymes which may continue to do their "work" on your vinyl for quite some time if they are not thoroughly and completely removed or neutralized. Trouble is, the enzymatic process is an active process, not just a deposit of residue that may or may not be removed. But if folks are convinced that any enzyme, once completely removed, is safe (and that it doesn't eat away at the vinyl’s constituent ingredients in the first place), and that the developer of such an enzymatic solution (there are a few) have done proper research to determine the efficacy of all their ingredients and can speak to such results in a direct and cogent manner, enzyme away.

Oh, you gotta get back to us on that one, Doug!

I did say "may"! :-)

Until this cartridge breaks in any subtle judgements like that will necessarily be hedged, second-guessed and highly suspect. Maybe doubtful too!
4yanx, there are meds for what ails you. buddy, you are making yourself look petty and foolish.
Why not try posting under your usual name, "jacksprat" so that we can see who may be proved truly foolish and so that I can tell "you" that I couldn't care less what you think?! If questioning what goes in to a product and the effects it may or may not have on vinyl is foolish, fine with me. I’ll be foolish. Oh, and there is also meds for those who don’t have the stones to post under their usual screen name. Last I heard, it contained testosterone.

Doug, thanks for the qualifier! Keep us updated on that :-)
Well, received my aerosole can of Premiere today. I have not had an opportunity to compare it to the others I've tried in terms of general cleaning and overall sonic improvement. I did, however, try to clean the mold off the record that was the impetus for buying the product in the first place, and it failed miserably. Whatever are its attributes, and they may be many, it did not remove mold. Waiting to see whether Paul's formula on the same LP fares better. Whatever the result, I appreciate the gesture Joe.
