Salting out is a process that can be used to dehydrate Isopropyl alcohol, i.e., separate it from water in an azeotropic solution. Dehydrated Isopropyl may be useful in making bio-diesel fuels. Removing water also increases the Isopropyl alcohol's ability to: > melt ice off your frozen windshield > dissolve water in gasoline > burn cleaner when used as a standalone fuel > provide your pet with an invigorating rub after his next bath, which is strong enough to dislodge stubborn ticks and fleas > serve as a powerful pet or human wound antiseptic > save you big $$$ (dough, ka-ching, moola, etc.) money* (*99.9% Isopropyl Iso-Heet at auto stores runs around 18.25 cents per ounce. 99.9% Isopropyl made from salting out 50%-91% generic retail brand Isopropyl runs around 6.73 cents per ounce. That is a savings of over 63%.) What you need: - bottle of 50% to 70% Isopropyl alcohol - a wide mouth glass jar and lid, or other leak and Isopropyl proof container - a pound of non-iodized table salt - a turkey baster with a reduced size nozzle - an empty bottle equal in size to the bottle of Isopropyl alcohol.
