in california, 99% rubbing alcohol is readily available at any local drugstore. that's the best stuff. depending on what kind of oil you use, i would reccomend something different. if you use synthetic oil (as i do because i am four strokes only) baby wipes work great. if you use caster, rubbing alcohol and windshield washer fluid works great. the 99% stuff is the best all around. thins epoxy and evaporates quicker than water, leaving your cure time a lot less, and is a lot better at getting those marks off too because it os that mucn more potent. also, if you are flushing out your engine, it is a great thing to have. that way, you don't have to dry it, and by filling your fuel tank with that stuff, you can clean out your engine if your jets get plugged up
