Unplug battery, remove motherboard, put it into an ultrasonic bath of 1 gallon distilled water, 103 milliliters branson EC. Then take it out of there and put it into a regular baking tray with 99% alcohol. Then let it sit somewhere where it can dry off for a while, maybe by a fan or an air filter or air conditioner. Then put it in an oven at 225f to evaporate any trace of liquid from the cleaning. Then pray. Also use a real ultrasonic cleaner, none of that jewelry cleaner junk!
