Because of the change of temperature, you can get clear sticker things that go over them to prevent it but otherwise you'll just have to keep wiping them.
Both, but condensation first.
When hot vapour is near a cold surface
Most likely condensation will form because when temperature drops the humidty rises. If the temperature of the can is low enough the humidty in the hot air when taken down to the temperature of the cold can will condense. The same thing happens on a lawn when the temperature of the air cools enough overnight to form dew.

Australia is more of a hot place than a cold place.
I think you'll find that they only steam up when going from cold to hot. This is the condensation process
That is condensation from hot engines in cold air.
First thing your glasses have to be cold. Second you have to be in a warm/hot area. Glasses "fog up" because when the warm/hot water vapor gets near the cold glasses, it turns into the "fog" you see on glasses.
Cold
they live in a hot place
evaporation is when liquid gets hot and turns into steam condensation is wen liquid gets cold and turns into a fog like substance
Condensation will form on the surface of the glass.
