Looks like that is for really dirty records. But it is similar to prioprietary solutions I've used for cleaning camera lenses (and a glass cleaning cloth I know will help clean xbox games and often make them work when not reading - same should apply to CDs).
I've tried warm water with a little washing up liquid with some success - but obviously that runs risks of residues (I would wash, rinse and them pat with kitchen towels to get the bulk of the water off.
I've heard the effect that Keith Monk's machines have - very good, but unobtainable (I actually missed a chance of picking up a second hand one years ago
) VPI, OKKI NOKKI and Moth seem similar. Now I'm tempted by the manual/bath cleaners - they are cheap enough and use the same (proprietary or DIY) solutions. I guess the problem with them is that they operate vertically and rely on soaking the disc in a bath and scrubbers to get into the grooves - so does the solution really get down into the groove when not helped by gravity and can the scrubbers cause damage?
Not much help I know. I'm also tempted to see what the microfibre cloths that make a good job of cleaning my spectacles, removing dirt and nose-grease might do to LPs - obviously would need one with a bit more nap on than the ones for specs.
