Question Using canned air duster

[WinSoft]

Sorry, not sure where to put this. I am a casual gamer and recently used a canned air duster on my laptop keyboard whilst switched off. I noticed that on one of the keys after there was a bit of liquid / condensation for a few seconds which then went away. The keyboard seems to be working okay. It just made me think, it says it's safe to use on pcs on the can - I just don't really understand how it works so was wondering if any techies could help.

The stuff inside the can comes out really cold, so sometimes you will see a bit of frost as a result. Nothing to be concerned about as it evaporates very quickly.

That's a relief, thank you.

Ensure you're not shaking, tilting or holding the can upside down. Each of those will increase the likelihood of spraying liquid instead of air.

Okay, thank you very much mate.
