Vinylisbest, I'm a huuuuuge proponent of a DIY wet vac system. It's really quite amazing and does everything that a $500 VPI does. Might not be very pretty...or if you put time into it, it *can* be pretty. Mine's uglier than a mud fence.
Basic cleaner fluid recipe: Distilled Water, 90+ % rubbing alcohol, about 40 drops of Kodak Photoflow and a little bit of unscented Lysol...about a cup seems to work well. The Lysol combats things like mold and other nasties. The Photoflow gets rid of the viscosity of water, i.e. it's tendency to bead, so that the fluid gets in the grooves. The alcohol aids in the cleaning also. The distilled water is the medium for the whole mess, and leaves no mineral residue.
Pour out about half the gallon of distilled water into a sterilized container. Mix the crap in the gallon. Fill back up with distilled water. Save the extra.
Get an old vacuum cleaner with a hose attachment. Also get a piece of crap turntable, something with a fairly stout platter. Rip the arm off, you just want this for a work surface. Now take the crevice tool and tape the end shut with some duct tape. Drill a hole just in from the end to fit over the spindle. Now measure and cut a slot that runs from the edge of a record label to the edge of the record. Cover the whole tool with cloth (I use a black sock with a slot cut for...the slot). That's your suction tool.
Now put a record on the turntable. Put about a capful of fluid on it. Use an old Discwasher (or similar) brush to swirl the fluid all around the groove area and scrub the disc in motions going with the groove. Then fire up the vac and rotate the platter slowly by hand, vacuuming up all the fluid. Now repeat the process, but with straight distilled water this time. Vac it off. Put your newly cleaned vinyl in a new poly sleeve (order them online) and put back in the jacket.
Also pick up a good carbon fiber brush for every day maintenance.
