I pretty much do just like you do etcarroll. Nitty Gritty, using a 50/50 mix of distilled water and 70% iso-alcohol, with enough of Ortho's enzyme cleaner to turn the water yellow, and 1 or 2 drops of Dawn per quart. Simple, cheap, and effective. How do I know? When the noise floor goes from sssshhhhhh to zero I figure it's working. I don't worry about a soap buildup, it's not enough to cause that. And if it did, my LAST stylus cleaner would remove it. The Dawn acts as a surfactant, making the water wetter so the solution can get into the grooves easily.
Used records are sometimes first cleaned in the sink by scrubbing the mix in using an old LAST Preservative applicator. I want very much to get into the hand-steamer thing. My cleaning method always takes the noise floor way down, but I think maybe steaming might remove a lot of the pops that remain.
