Jesstzn- Yeah, I use it via PC (far more often than by hand).
One thing though- I find it hard to predict just how well it'll clean, despite its abrasive content. Using it after M205 (even after I'd IPA'ed it...this was before I learned my lesson about how to strip M205 oils) resulted in a *terrible* mess that was an incredible PIA to sort out. SO, I'd sure do a test spot before assuming "hey, it'll take that SG/M16 combo right off..." the way one might expect.
And I sure would'nt expect Dawn to strip it off either.
Eh, I'd wash it with something like ValuGard's "A", and even with that stuff I'd let it dwell for a good long time. Or use something like PrepWash/Eraser/etc.
