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

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.

Cello:
Would I be well advised then to reserve Premiere for a one time application to new LPs and stay with whatever solution I find best works for removing dust, dirt, debris from older records?

Count me among the converted! I received the samples which Joe so graciously offered to send me. I must say after following this post I was somewhat skeptical about applying Paul's product to my records, but my collection,as impressive as it may be, does not include that many collectibles or rarities and so I was more than game to give it a try. The first thing I did was try it on the same record that has the mold problem; the one which has been resistant to anything I've tried, including, most recently, the can of Premiere I received just the day before. I'm sad to say the mold still LIVES. I tried applying Paul's stuff twice and while the mold may be somwhat lighter in appearence, it is still visible.
But trust me, I am not writing to tell you that I am the least bit diappointed in the product. To the contrary, I was up much too late last night rediscovering many of my most heavily played recordings. There is no question that Paul's solution revealed subtle details which I had not heard before. Aside from being quieter, everything about what makes vinyl a superior medium was present in abundance. Cymbals shimmered more brightly, soundstage was deeper, bass was more robust. I've already blown through the samples and, to tell you the truth, I don't feel like listening to another record until I've cleaned it with Paul's solution. I don't think I overstate the case to say that the difference in Paul's solution to what I have been using is nothing short of a component upgrade. I will leave the chemical analysis to others. I'm sold. I will be ordering from Paul later today. Since Joe turned me on to this product as a sheer act of kindness, I will be happy to refill his bottles and mail them to the first person who asks. I only ask that they do so on condition that, if they are as ecstatic about the product as I am, that them perpetuate the favor for the benefit of another audiophile. This stuff is too good not to get the word out.
Best Wishes Everybody.
