CLEAN RECORDS WITH WHAT?????

I wouldn't recommend getting records wet before you suck or sweep out all the dust or the vast amount of dust and than you should apply liquid.
If you will apply a liquid onto dirty vinyl the dust will get stuck onto groves.
So the first thing to do is to vacume it than use Discwasher record-conditioning brush with a small amount of discwasher liquid(or other professional brand) along the groves until the liquid dries out.
Place your record back onto VPI16 and vacume it from statically accumulated dust particles.

What's a good source for Torumat cleaning fluid?

Never use alcohol to clean records. Alcohol damages vinyl, over time it will become brittle and you may see visible streaking on the surface. As far as not putting a liquid on the vinyl before you vacuum, that's just ignorance, any good detergent / surfactant breaks down any bonding between the dirt and the vinyl. For 90+% of records, the proper surfactant and relatively pure water will do an excellent job. As a Chemist, I can tell you that we used this 30 years ago to clean absurdly expensive analytical equipment that had vinyl measuring tubes.

Music Direct in Chicago, a measly $70 a gallon. But, a gallon cleans a ton of records.

This recipe came out of the Absolute Sound about nine years ago and has served me well since:One gallon of pure distilled water,one pint 97% alcohol,10 drops of Kodak photo-flow and 10 drops of windex.This will run you about a dollar per gallon.Alot further than a gallon of gas will get ya.No sonic degregation has occured on any of my records since using this formula and the sound is as good if not better than those so called mega buck cleaners.
