Here's their instructions and manual download, to start at least:
Instructions & Owner's Manual - Spin-Clean® Record Washers
It's really easy once you get used to it, but yeah, do your first trials on a non-valuable/non-favorite record. I stick pretty close to the instructions - wiping dry clockwise, then using a dish rack to let them finish air drying for a few minutes before re-sleeving. Don't worry about little droplets of water getting on the labels (doesn't happen often, but does happen) - just dry them with the cloth once you take it out.
Take care when doing 10" or 7" records - the rollers are a bit less stable in those slots and can "jump" out. I have to go slower and use one hand to turn the record, and the other to keep the opposite-side roller from jumping, usually.
Hmmm - if I think of any other tips I'll write back, but that's all I can think of for now.
