I always seem to be posting this link, but here it is again:
I use the modified crevice tool described here: http://www.teresaudio.com/haven/cleaner/cleaner.html
and clean the records on top of a TT I bought for very little at a Sunday market (removed the tonearm and put a switch in to turn on and off). It works very well for me. I start with a steam clean and wipe it down with a Selleys Super Cloth. Follow this with a clean with cleaning fluid made from 30% isopropyl, 70% distilled water and a few drops of dishwasher rinse aid, this is vacuumed off. Lastly I clean with straight distilled water, this is a rinse cycle, and vacuum off the water. I have 2 modified crevice tools for the last 2 stages and I apply cleaning fluid and distilled water using Disc Doctor brushes. This is a cheap and very effective method for me. If I really can't get a stain off I wash the record in warm water with one third vinegar, it gets a lot of grime off.
I'm not loaded either but I reckon my method works just as well as an RCM, it just takes more labour.
