Cheap toaster oven kitty litter (cheap unscented), foil tin large enough
to hold discs, and some brake cleaner. Spray them down with the cleaner,
let them dry a bit. A layer of litter, a disc, layer of litter repeat.
Toss the mess into the toaster oven (OUTSIDE IN THE OPEN AIR !!!) Set
the oven for 400-450 degrees. Let them cook for an hour or so. The heat
will boil the oil out of the material and the litter absorbs anything
that doesn't cook off.
