Denatured Alcohol! (Score 1)

It might take the whole quart to do a keyboard, but for cell phones and the like, I go to home depot and get a can of denatured alcohol in the paint thinner section. As long as it doesn't contain methyl ethyl ketone, it dries faster than water and gets more gunk out. I once spilled a full venti caramel macchiato on a laptop keyboard... disassembly and q-tips with denatured alcohol worked faster and better than plain H2O. YMMV

Plus you can set it on fire later...
