I still prefer vodka.
But yeah, I generally don't clean my keyboards at all. The only time I do is when I get a new keyboard in that is used. The first mech board I got I used for 2-3 years exclusively and I don't think I ever touched it. Only a couple of months ago did I give it a once over with a mister clean magic eraser. If I ever bother to clean it (or if I figure out how to dye abs keys without killing them) it still needs a full disassembly and a dishwasher run.
I never did clean my original rubber dome, but it's still in pretty good shape, actually.
I only go all out and pop all the keys off, etc if it is horribly, terribly, untouchablely dirty. Or if I'm about to do a dye/paint run. Other than that I use the magic eraser, it seems to be by far the easiest way to clean one quickly (still for new-to-me used boards mainly).
