Re the posting from Saskatoon, while I think it is perfectly fine and sensible to provide the warning re the toxicities of such substances, that being the purpose of a MSDS (Material Safety Data Sheet) to provide the user or receiver of chemical substances with such information, in truth no one seriously is likely to ingest such materials, or be exposed to them over a long and consistent time frame.
Therefore in practical terms it is wise to apply a degree of common sense and appropriate precautions with what ever substance one applies to a surface to remove an old finish, be it Vodka :D, Metho :2tsup:, paint stripper or whatever.
