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

I can't speak to the Buggtussel in particular, either, mine was more a question of enzymatics, in general.

Patrick, I agree with your "what to lose on an unplayable record" question, too. But, when was the last time you saw that qualifier as a marketing or advertising boast and how many general browsers for vinyl cleaning fluid are even going to imagine there'd be such a distinction? Granted, if certain prducts move from the "use them on all your of vinyl without worry" to "use on otherwise unplayable records as a last resort", I might try some of them myself. I'd just hope that such a distinction would be clear to everyone with concerns.

Pitch the LP and go on to the next one. (That is, unless you are very young and have absolute confidence of a very long life ahead.)

Hey gang. I'm at work right now so I can't dish out the needed dissertation to help clear-up some of the concerns about enzymes, how they work, the specific class of enzyme in Paul's product, the topic of plasticizer leaching, etc. I'll post later this evening.

Mrkidknow, it seems that you have stated elsewhere that you were at least one person consulted, perhaps the main person consulted, in the development of this particular product (and since you've indicated that you will be addressing a specific product and not enzymes in general). As such, whatever you post will hopefully be illuminating. Because you are not exactly an uninterested party, please do not take offense if you are asked who you are (other than Mrkidknow) and your qualifications to make what I assume will be a chemical/biological discussion. Also, please do not take offense if independent verification of ingredients or processes is sought.

Pardon my fatalism (if that's what it is), but I just cleaned another handful of my favorite LPs with Paul's stuff. Anyone so concerned about using the AIVS treatment before someone Higher Up blesses it -- which is unlikely to happen to the satisfaction of some folks here -- may feel free to send me what's left in the bottles. It will be put to good use, "ruining" my records. Dave
