Geoff's mention of Permaclean reminded me of another product from the same stable, Permastat, which was supposed not only to clean the disc but also permanently remove static (which causes clicks and pops just as much as dirt). I had variable success with it, and found that treated LPs would stick to the insides of the inner sleeves when put back after playing. I hung on to the felt pad, though, and now I just dampen it with a few drops of isopropyl alcohol before playing. I clean the side I'm going to record immediately before playing it. It's well worth checking the stylus for fluff picked after cleaning (the cleaning loosens debris that may still be present on the record's surface) after each LP side, or even after just a few minutes of playing. The hazard that comes with rinsing under the tap is that tap water has got calcium salts in it which are left behind as a minutely-crystalline residue in the grooves as the water evaporates. I have never had success with the kitchen sink method and I would not recommend it. Two other hints for reducing the effect of static: do your recording on a damp day (or humidify the room in some way) and keep the record deck lid down if it has one.
