Want to get rid of a wart, but don't want to use harsh salicylic acid or pay for an expensive wart-freezing kit? This instructable will show you how to freeze off your own warts for 1/3 the price.
Step 1: Get the Supplies
You're going to need a can of computer duster from your local office supply store. The ingredients in the one I've used is simply tetrafluorethane gas (non-carcinogenic, and non-flammable for the record) compared to the retail wart remover which is dimethyl ether, propane and isobutane.
Also pick up a pack of plastic Qtips.
Duster: USD$7 for a giant can (12oz)
Qtips: $2.50 for 375
USD$25 for a wart freeze off kit (12 uses total)
