The contact cleaner spray that Ashton has often mentioned might be a better first choice. https://www.google.c...act+cleaner+spray

You can wash printed circuit boards. The main thing is to make sure it's grounded, and make sure it's totally dry before powering up again.

I dunno if Scrubbing Bubbles is the best choice - you probably want to minimize the time in the water and the time coated by the cleaner, to be safer.

You don't have too much to lose if it's not working now, but it's not for the faint of heart.

Good luck.

Cheers,
Scott.
