I dropped an early smartphone (actually quite dumb) in a bucket of emulsion paint. Now that is really dumb.
I took washed it and took the back off, and battery out - there was a lot of paint inside. I washed it in water again (what a waste of paint).
I left it to dry for about 24 hours and hey presto it booted back to its previously dumb incarnation with no faults whatsoever.
Kind regards
