Re: [ARSCLIST] cleaning lacquers ("acetate") - palmitic acid deposit

[H D Goldman <thedoctor@xxxxxxxxxxx>]

With all due respect to those who have replied to this thread, a few  
comments are in order for those who have not heard them before.

Our MIracle Record Cleaner is milder toward phonograph record surfaces  
than ammonia solutions, has been repeatedly demonstrated to thoroughly  
& safely remove palmitic acid residues, and unlike ammonia solutions,  
thoroughly & safely clean the groove as well.

Purchased in larger quantities it is hard to justify using audibly  
less effective fluids based upon cost alone.

Cheers,

Duane Goldman
