has anyone tried ultrabit platinum on their cds

I use old soft cotton hand towels.

WARNING. RE "Elizabeths" comments above!!
Mequiars Scratch X will SCRATCH the surface it is used on. I have used it in automotive polishing.
It works to remove obvious scratches by its abrasive(polishing) action. In the automotive business it is called a polishing compound-all of which work by abrasive action. It is NOT similar to Ultrabit Platinum-which is not an abrasive.
I enjoy this forum & appreciate everyones right to their opinion and have nothing against Elizabeth and I'm not questioning her enjoyment of the product; however, as always, not everyone's suggestion is appropriate. The swirl marks resulting from a "polishing compound will NOT help the laser read the disc. We're talking apples & oranges.
Happy listening as always. pete

Talking about price
--Ultrabit Platinum is an utter "SteaL".
It improves CD sound of my Lexicon RT-20 by the equivalent of a component upgrade. It is like having an additional exquisite AC power filter in my system(Spectral/MIT). As my Russian friends say "cheap like Borscht". Perhaps low resolution systems may not benefit,that I just don't know; but for high resolution systems-and particularly large dynamic orchestral works-it really clarifies much of the complex intense dynamic passages which certainly increases my enjoyment significantly. Cheers.

Flute concertos benefit beautifully from Ultrabit Platinum with far greater presence and subtle vibrato.

Fplanner2000, your description of benefits is very apt. This certainly an item it's nice to share the "surprisingly" good news on.

Fplanner, you mentioned having to buy the cleaner with the treatment. I have found this quite sensible as I note excellent benefit from the cleaner omly on CDs that I have already cleaned in my previous way-which was using the cleaner for my prescription glasses with coated lens, followed by a filtered water rinse. The treatment simply adds to the cleaner.
