I've always thought that if you spill liquid on your PC, the first step is to turn off the power supply as quickly as possible. But I'm worried about that residual electricity that doesn't clear until I press the power button, which can cause a brief on/off flicker. Should I just turn off the power supply and repeatedly press the power button to drain it? Or could that sudden jolt of electricity while there's liquid on it cause more harm? I haven't had to deal with this yet, but with my cat sometimes napping atop my PC, I can't help but think about the possibility of a mishap!

If it’s a drink like soda or juice, you're going to want to go a step further. After powering down and unplugging all components, use some isopropyl alcohol to clean up the mess. Just make sure to let everything dry completely before you even think about powering it back on!
A quick tip: if you notice parts of your computer still lighting up after turning it off, it might be holding a bit of power. That’s a good indicator of how long you should wait. Just don't rush the drying process. Let it sit for a few days before any testing!
First off, definitely turn off the power and unplug everything right away! You don’t want to risk sending voltage through any components that might be wet. Instead of pressing the power button, just leave the side panel open for about 24-48 hours so it can properly dry out. Be safe!
Make sure to remove the CMOS battery too and wait for the capacitors to completely discharge. After cleaning with isopropyl alcohol, give it plenty of time to dry. You might want to think about replacing your PSU just to be super cautious. It's better to be safe than sorry!
