Sputniks,
I use a different technique than Photon46 described.
First, I bought a Disk Doctor Brush, as it was bigger (and better, IMHO), than the brush that comes with the Nitty Gritty.
I also use Record Research Labs (RRL) record wash as my regular cleaning fluid. (The Nitty Gritty Pure 2 was pretty good, but I prefer the RRL myself.)
I put a pretty decent amount of fluid on the brush and then brush the record in circular mostions around the record. (The record is lying on the plastic inner sleeve, btw.) I go 2 or 3 times around the record, in both directions.
Then I put the record on the machine and vacuum it dry.
(If you have the small wire brush that comes with the N.G., (I got mine with the replacement pad kit), you should use that to clean the cleaning brush and the pad on the RCM every so often.
That is my technique, make use of the information as you see fit. I get the feeling that everyone seems to have their own method, some better than others, but who really knows which is the ultimate method. (Well, I suppose that the ultimate method is what some people do, which is wash the record on one machine, and vacuum it dry on another. A bit too much for me, but probably a slightly better method to thoroughly clean the record.)
Good luck!
PS I agree that for the money, the NG 1.0 is a fine RCM, and will do a satisfactory job of helping clean your records.
