Maybe I'll get that ultrasonic cleaner ready for him (if I decide to be a nice girl ...)
Speaking of, I've got a mixing desk renovation project with a lot of C&K miniature toggle switches on. Those are nearly all intermittent, and while contact cleaner works OK for a short time, I'd really like to do better. Would an ultrasonic bath (mine's a jewellery style toy, TBH, but) work? And what fluids would one need? I've seen the Dalibor Farny videos. He uses beakers in the bath, with (I assume) distilled/deionised water and some cleaning agent. The latter mostly to break surface tension, right?
Would this help? Am I on the right track?
/M, sometimes a nice boy, like now, when he's made lunch.
