Step 1: Get the supplies
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)
Step 2: Prepare the supplies
Step 3: Freezing Part
Wait about 10 seconds and apply to the wart you wish to remove. It's going to sting, but it's just like getting something liquid nitrogened at the doctor's office
I'm not responsible if you maim yourself somehow doing this. Use common sense.
