I've resurrected more than a few beverage drowned keyboards with this protocol. Laundry sink full of painfully hot water and dishwashing detergent (I like Morning Fresh Lemon scented) for a soak, then a scrub, then a rinse in equally painfully hot plain tap water, followed by a liberal spray bottle distilled water rinse and finally a super generous alcohol spray bottle rinse. 99% IPA is expensive when bought in the Jaycar 125/250ml bottles but cheap in a 5/20lt tank. ProTip: Don't use a scrubbing brush on your LGA socket... Without active power, water isn't instantly harmful to electronics.
