I do some maintenance on the neighborhood ice-skating rink. To control the lights, there is an outside electrical panel that is locked with a padlock.
This padlock always gets frozen. Every time I need to mess with the light controls, I have a hard time trying to even get the key in, then I cannot even turn it. The only solution I have found so far is to heat it up with my bare hands, which risks frostbite. That was sustainable when the weather was good, but the temperature is going down to -25 Celsius (-13 Fahrenheit) this week.
Is there a easier way to unfreeze it?
