'Wet' cleaning doesn't necessarily imply cleaning only with water. Nrchy made it clear water was the 3rd step in a multistep process."
Other than water, I'd be curious to know what other liquid base he's using in the first two steps.
I don't know what Nate's answer will be, but in my case the other liquid is Premier, a product of Micro Care.
This is the only product other than the original "First" by Nitty Gritty that dissolves mold release and other contaminates in one application.
First was banned by the EPA many years ago, I have only one bottle left that I keep as a reference against other cleaners.
Premier is based on Vertrel, a Dupont substitute for Freon that seems to be equally effective and yet safe for the environment (as far as we currently know).
Like First, Premier should be followed by Record Research, Lloyd Walkers cleaner, Audio Intelligent or whatever you're currently supporting as best.
In any case, there is no doubt that removing debris from old and new LP's improves sound.
This was true with my Nitty Gritty, which was clearly beaten by my VPI 17F and improved again when I upgraded to the Odyssey RCM, which is basically a hot rod version of the Keith Monks, but built in Germany.
