The peeps on those retro computing channels are genuinely washing motherboards all the time as part of restorations.
The one pictured here is just some normal gigabyte motherboard from 2008 so it’s probably just a joke, but there’s definitely real reasons to give electronics a bath.
I’ve got a WLED Christmas lights controller (basically just an ESP32, 12v power supply, and hand-soldered board for supporting components) that needs washing because I left it outside after Christmas to see if the homemade case would stay waterproof long-term, and the answer turned out to be “no.”
