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

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

I admit that I've been a little intimidated to post my concerns about this new cleaner, because if you do, there are those who try their hardest to make you feel poorly, just for stating your opinion.

Some of us collect rare, valuable records and it would be un-wise and irresponsible for us to use anything questionable on them. I'm the guy that has the $300 Fred Jackson Blue Note. I also own 2 of the 500 original 1568 Mobley's. I've been told that these sell for between $2 to $3K. I also own most of the original 1500 series Blue Notes and have spent thousands of dollars acquiring them.

Certainly, even you dopogue, can understand why some of us with collections like this may take extra caution to make sure the cleaner is safe and has had suitable testing and research behind it to insure our records are not harmed.

I realize that a replacement value offer was made by the manufacturer, however he advised me against using his fluid on my $300 Fred Jackson "Hootin' and Tootin'".

If this fluid is being offered for use on garage sale VG condition or less records, then fine. I don't waste my time with such records. But to insinuate that 4yanx, dougdeacon or I have issues because we won't follow your lead is ludicrous.

Wow, that puts me in my place. And 4yanx, I'm sorry your team lost. Jes45, I wouldn't dream of telling you to use ENZYMES on your discs. I'm amazed that you actually listen to them at all, must play hell with the resale value. All the best, Dave

I'm not a scientist but I didn't sleep through all my studies at university. Animal fats are used in making steel to provide certain characteristics for workability, strength, etc. What it is not is steel with fat added. It becomes a very complex molecular structure. Even if you weld the steel it will not leech out the animal fat. I'm sure that a complex compound of molecules found in vinyl formulations is similar in concept. If it were as simple as vinyl with fats added then certainly the pressure of the stylus would make the fats leech through temperature rise with a couple of tons per square inch pressure. I don't know how big enzymes are but I'm pretty sure they are bigger than individual molecules. We all know that salt is not good for concrete. But one doesn't claim that putting salt on it makes the portland cement leech out and that's why it crumbles. It is no longer sand, water, lime and portland cement. It is concrete after the ingredients have had their chemical reaction. This is not offered to make a fuss with you guys. It's just food for thought.
