Dear Wil:
You want to use the USP type mineral oil (used as a laxative). However,
you should be able to find stores in the US that charge around  US$2.00
for a pint.  Do you have
Drug Emporium, SuperKmart, Pharmor, Revco type stores in your area?
Those would carry medicinal type mineral oil (their brand is equal in
quality to USP mineral and acceptable.  Good luck.
Best regards.
