Discwasher - I still have one. Vintage 1975.
The records are not that dirty so the dishwasher soap and water will probably be enough for me.
You just have to be extremely careful about what and how much solvent you use.
BTW, for those of you who like the old Diskwasher system, it is still available. http://www.parts-express.com/pe/showdetl.cfm?Partnumber=200-436
