I got some good advice from a guy named Roger at Music Direct, who suggested I try MoFi when I started listening to vinyl again last year.
On Lps with dirty pop/click grunge, I use the MoFi Super Deep Cleaning fluid. I also use a MoFi brush. I get the fluid on and spread it around, then I use a gentle scrubbing motion for about 30 seconds. (Roger didn't mention the scrubbing--I decided to try this after I found I wasn't seeming to have enough success without scrubbing, and I saw some suggestion somewhere that scrubbing helped, and let me emphasize -- GENTLE SCRUBBING ON PROBLEMATIC RECORDS REALLY WORKS.) Then I walk away for about 2 minutes, then come back with the brush for 30 more seconds or so, then vacuum it off. (I use a VPI 16.5)
After that, I do a simple and quick "rinse" with the Super Record Wash, vacuum it off, and I'm done.
Does that work 100% every time? Nope. There are some records that I haven't been able to fix. I'd be inclined to try an alcohol-based cleaner for those (whether it's viewed as a no-no or not--once isn't going to kill a record, in my view), however, I haven't looked hard enough to find one. (I think VPI cleaner used to have alcohol in it, but I really don't know.)
I've read darn near every long post on Audiogon on record cleaning fluids (which are exhaustive and exhausting), and I do not recall ever having heard that MoFi fluids leave a residue. And, frankly, if they do, and that's why the records sound so fine after a good cleaning, then I'll take the residue.
One note of caution. I think I even did a post about whether scrubbing is potentially damaging to records...but I'm past 50 and don't remember everything... I suppose there is some theoretical danger to gentle scrubbing, but if you're having a problem getting a dirty record cleaned, I think it's worth the trade-off, risk-wise, and out of the 100 or so records I've cleaned with scrubbing, I don't think I made any of them worse-off. But you've got to be GENTLE.
