Re: Replacement for acetone?
In the U.S. any ethyl alcohol not specifically manufactured to be sold for human consumption must be deliberately poisoned to prevent consumption and/or punish one for doing so. The cheap corn liquor you purchase at the hardware store can and will (by government mandate) kill you. Any consumable alcohol will be priced according due to government taxes and will be cost prohibitive for swabbing and cleaning.
Your country may vary.
