Step 3: Freezing Part
Invert the can and give a couple of short bursts of freezing liquid until the Qtip is saturated with it (you'll see it splash off). Avoid getting the liquid on you anywhere else than the wart because it can cause frost bite.
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.
