OK… let’s put it this way… what’s fast for you, may be slow for me (or the other way around)… but you don’t want a “fast” drying solvent when cleaning the pad or it will dry out before doing the job… or you have to put in a sealed container to soak.
Naphtha will remain in the pad long enough to dissolve the spent polish before completely drying up… better still you switch on the Dremel and let it “spin dry”.

I have been doing this with one such pad for countless polishing/cleaning cycles with no problems… it is amazing to see the pad looks like new after it is cleaned. There are many other solvents that may work better (faster), but most tend to “strip” and eventually destroy felt fibers, but Naphtha does not… you should try it.
