Are you sure about alcohol being ruinous, or can anyone else comment?
I've used a mixture of 80% HPLC grade water (ie. very good double distilled-
deionized water) and 20% isopropanol (of similar purity) with a few drops
of Photo-Flo/gallon thrown in to improve wetability for years now.  I
haven't noticed any ill effects on any records (though they don't get washed
often, once for 20-30 plays which essentially means once for most of
them).  I'd always assumed the alcohol helped dissolve oils and organics
(mold release compound on new records?).  I'd be very interested to hear
more on this.
