Don't doubt what you say at all about Alcohol, but do wonder why you would then say Denatured Alcohol would be OK? I'm certainly no chemist, but was of the belief that Denatured Alcohol contained some other various chemicals in it to essentially render it undrinkable? (And no doubt therefore un-taxable as well?)
I probably don't know what the heck I'm talking-thinking about, and maybe I'm thinking of something else?
I would think the Novus wouldn't be a good idea on the Clear Frosted Acrylic Platters, unless you want to remove the Frosted Matte Finish? Doesn't all the Novus Products contain an abrasive?
As for the Black Platters, isn't this material actually Delrin? Or?
What popped into my mind as a good alternative cleaner for either type Platter, since it doesn't appear to damage the Media we place upon these Platters, is a good Record Cleaning Fluid (Without Alcohol)?
Generally for dusting my platter+Plinth, and removing fingerprints-etc I use AIVS Pure Water Rinse. The Pure Water seems to not leave any spotting-streaking, in that it is mineral free. Mark
