Main concern was that if the water from the race had started to corrode some components already, it would have all been a bit futile.

A few months ago I had a receiver start to do strange things, and when I examined it there was fine rusty corrosion on the pcb. Hmm.

Anyway, I'm using the past tense about the switch now... Somewhat foolishly, I'd just tried immersing it in a water solvent (acetone) to clear it out and it killed the plastic and the rubber insulation on the wires altogether. oops.

My bad, really, as I should have known that the orange plastic was polystyrene, which dissolves into acetone leaving a slimy goop. I just had year 10s make slime by putting PS cups in acetone for a practical about polymers a few weeks ago!

im struggling to see how that works in bold.

water is an insulator out of curiosity, what water did you use?
