You don't take it off, you let it wear off. I think that is the secret. Like I said, it is an old wives tale. I personally have never used it. I have used superglue though on a deep cut I had on my hand from a knife in the sink (washing dishes, didn't see it but felt it). It worked great. No emergency room and by the time the glue "dissolved", the cut was pretty much closed.
Kinda like the hairdryer for an ear infection thing or holding a lemon slice under your nose to help with nausea.
