I built my own cleaner on the design of a drive thro car wash system. I am a aero modeller/flier so have lots of servos/materials and tools.
Its basically a rectangular tub with a horizontal spindle and lock for the record disk. I have two (one for each side of the record) high pressure jets (tubes of aluminium drilled with tiny holes) to blast the surface of the disk. The lid of the unit covers the disk to the lower part of the label so it doesn't get saturated (after bit of experimenting and lost labels later). I pump distilled water under high pressure to blast the grit and muck from the record for 2 minutes and then the timer servo switches off the water and then blasts filtered air for one minute the dry the disk surface.
A second timer signals the procedure is finished. No chemicals, no mess other than to empty the drain tank underneath when a float contact says its full. The whole cleaning blast area is 1/4 the record area. They come out nice, clean and dry. Amazing what a bit of tinkering will do and watching drive through car washers.
