Can you clean a PCB in a dishwasher? I just hope it doesn't shrink:

Please take this video down before someone else is stupid enough to follow your advice. The salt from the dishwasher will still be inside electrolytic capacitors, inside sockets and who knows where else. No matter how much rinsing and drying you do afterwards, you are causing serious longterm damage to the board. It will work today, but inside things have started to degrade and it will most likely fail sooner than it should.

I just learned today, that some people disable salt & whatever else on their dishwasher, due to instructions on using "multitabs" where it all should be embedded (I never bothered reading on those, could be wrong :) ).
Anyway to be fair, he does warn people against doing it.

Thanks guys. I do not use salt in my dishwasher, and do not use a pod, so there is no salt in this equation. But you raise a fair point I've added that little warning to my comment pinned below the video.
Thanks!

It is not so uncommon to wash PCBs for the arcade PCBs users. I myself have bought one PCB that (I know) has been washed: I took some ICs apart, and I noticed marks left by water when it was dryed with a hair-dryer, under some sockets. The seller admitted he washed it before auctioning, and also said it was a common practice. The game works flawlessly.

Fortunately, I have isopropyl alcohol and ultrasonic cleaners at work & at home, so I don't need to put my electronic devices in the dishwasher :D

The problem is that most people will have salt in their dishwasher and don't realise / forget that it will always be in the equation. The amount of washing / rinsing etc with Isopropanol required after the dishwasher is the same amount of work that you'd need to clean the PCB without putting it in the dishwasher in the first place. My chosen method is a small bath of Isopropanol and a soft toothbrush (I usually borrow the wifes :D ), which is more than enough to get the PCB safely shining again.
