Hey everyone! I'm about to swap out my PSU and GPU, and I'd really like to clean the dust from my PC while I'm at it. I've heard that using compressed air is a good way to do this, but I'm worried about the risk of short-circuiting my motherboard or other parts due to any liquid in the can. I understand that if I use the right technique it should be fine, but what if something goes wrong and liquid gets on the components? I plan to have the PSU unplugged, but should I be concerned about the CMOS battery too? Any advice would be appreciated!

I’ve done this a bunch of times, just remember to unplug your PC first. When using canned air, there might be a little residue from the propellant, but it’s usually not a big deal. Make sure you don’t spray directly at components, though.
Always be cautious when using compressed air on electronics. It’s best to avoid blowing under chips or into connectors. Aim for the heat sinks and make sure everything is unplugged. If you’re really worried about liquid, let it sit overnight after cleaning, just to be safe—liquid can damage things only when powered on.
The liquid in those cans isn't conductive, so it shouldn't damage anything if you use it right! Just make sure to keep a distance and you should be fine. I’ve cleaned my PC multiple times this way without issues.
