"IPA is a lousy solvent for grease and oils."
Audiofeil - you're kidding right? I have to beg to differ. The topic was cleaning fingerprints off a hard surface, not laundering clothes. IPA is widely used in industry as a solvent for a range of organics and as a degreaser and cleaner (e.g., for optics). One of the concerns using it on LPs (as I'm sure you're aware)is leaching out plasticizers and other additives (hence the 7:1 dilution and comment about limited time on the vinyl surface).
To Rushton, Dougdeacon and others - wasn't claiming dilute IPA is the best but it is certainly cost-effective and as such is an economical first step for removing heavy soiling and conserving more expensive proprietary products. BTW - once I get through the KAB solution I'm using as a 2nd step, I'll begin using the AI products I purchased.
