How remote of a place is it that there's no rubbing alcohol available and it has to be shipped in? I've lived in pretty remote places (aka, 20mi from the closest town of around 2000 ppl) although limited to the u.s. It should be sold anywhere that has bandaids, either a drug store, pharmacy, any health/beauty aisle, convenience marts like fueling stations, just about anywhere. It may depend on the type of acetone, the paint thinner type I've used leaves a residue where alcohol doesn't. I wouldn't call acetone abrasive, rather corrosive depending on type/strength. I've never worked with lab grade acetone, so that might be something entirely different. Still find it hard to believe that acetone would be any easier to get than rubbing alcohol.
