If you're hands are greasy from the blackest and dirtyest grime from working on your s10 , I've got two better solutions to get your hands squeaky clean. First one is this can of engine degreaser as shown in the pic below. You just spray it on, rub your hands together and rinse and your hands get squeaky clean if you don't mind the little tingling sensation from the ingredients that break down and dissolve grease. Second one is just as good if not better and there's no tingling sensation either. Both of these work way better than and made for mechanics hand cleaner or even regular dish soap. Just spray rub hands together and rinse, repeat if really bad.
