It would be nice to have a small ultrasonic cleaner. But to not make it break the current vibe here are some ideas:
- make the tool relatively expensive (mid to late game transition)
- make it small enough that for example the atari case case won't fit
- only disassembled parts can be put in it
- some parts would break if put in.
- add delay to it
- definitely make it buzz and ding but quiet enoug so it doesn't bother
