Chazzbo - Mikey Fremer is talking about a reverse osomosis system NOT laboratory (a.k.a. pharmaceutical) grade water. To purify the water some people will put the same water repeatedly through the RO process 5 or 6 times to remove impurities. Very weird but OK (I guess) if you have the time.
EVERYONE - you simply MUST try STEAM cleaning! No matter what system you use - even if it is dish soap, dishwasher soap, or a "let dry & peel" technique. Steaming, with the best water you can get, is for EVERYONE and does a wonderful "finish" job as well. The Egyptian cotton terri cloth for drying is a really nice added touch too! However a common wooden dish rack will work nicely as well. For those that worship at the altar of self-appointed Pooh-bah and vinyl techno-Shaman Mikey Fremer, steaming is one of the things he wants the purist water for (as well as mixing). But REMEMBER, Mikey did NOT discover steam cleaning LPs - Charlie Rehm DID!
AS FOR EVERY TIME I PLAY A RECORD - jury is still out on the minimalist approach but carbon LP brush and a stylus brush swipe seem necessary. HOWEVER, reducing static (which is level dependent upon Relative Humidity) is a biggie but I still need to perform empirical testing with measurable data to be certain what is easiest yet very effective.
