My only contribution here is to amplify the excellent points already raised. I use a VPI MW-1 Cyclone for pre-clean, rinse, (a second pre-clean if the record is very dirty, rinse, second clean, then final rinse and dry. I use a HumminGuru Nova for the final rinse, then back to the VPI for dry. All fluids as defined by Neil's post and in his book. This is quite easy to do, takes perhaps 5-6 minutes per record total. I will opine from my experience:
1. Neil's book is invaluable
2. If you are on the horns of a dilemma between a scrub and vac machine and an ultrasonic machine, ask yourself if you intend to clean only new or near new records, for which the US machine should be preferred, or if you have or intend to buy old/dirty records, for which the vac machine should be preferred. If you are not sure because you are just starting out, I recommend a vac machine because it is more versatile.
