Cello,
I believe that Tom tested Audiotop also, but I'm not 100%certain. I know that if he did, he didn't get it from me, nor anyone from my group. (He had 3 friends give him products). If it is important to you, I can ask.
If I'm not mistaken, we tested everything available, even a few that aren't available anymore, like Jena Labs.
My purpose of my post wasn't to brag on one particular product. To me, it was important to share the info that our friend with all of the test equipment found. He has chosen to stay nameless because he conducted these tests at work, using their equipment and on company time. One positive is that he has found a cleaner that helps him send a low BLER data disc that will not have long term detriment. Maybe he should put in for a raise?
The bottom line is that if Audiotop is free of petroleum distillates, doesn't contain a wax or a substance that will leave a film and doesn't leave scratches, it is likely safe. Shine Ola comes from a reputable company that has been around for while, Record Research Lab. It also comes with a 3M micro fiber cloth that does not scratch the disc surface at all, unlike other supplied cloths.
Yioryos, I've been getting mine at Red Trumpet. I got my last bottle at half price. They have a special, buy $30 worth of records or CD's and you can buy RRL products at a discount. (www.redtrumpet.com or give them a call.)
I hope this helped ...
