If a ring is stuck too tight on your finger, you can try what the pros in the emergency room do: spray some Windex. That's what broadcaster and writer Buzz Bishop learnt in a recent mishap.
When Bishop's ring finger was injured and the ring wouldn't come off, doctors feared they'd have to cut it off. But that's when a nurse showed up with a bottle of Windex.
A few squirts on my finger and a gentle rotating tug and it was off. I was expecting soap, or vaseline, or something like that, but .. nope. Windex.
The nurse said Windex is not only a lubricant, but it has properties that makes your skin shrink a little bit making it easier to come off.
Pretty handy to have a bottle of that stuff around, since it can also help you fix stuck zippers.
