You don't leave anything other than distilled water or relatively pure alcohol to "dry out" onto electronics. Get a gallon of distilled water (usually less than a buck a gallon at Walmart and similar - we keep a couple of gallons on hand at all times) and rinse the tea out thoroughly. This process should have begun immediately as NOT to let anything dry out. If you warm the dist. H2O first it'll work better at getting stuff out. Then rotate with shaking to get the majority of water out of the nooks and crannies, then hang it up to dry with one corner at the bottom to get the most thorough drying.
. If you wish, you can follow a reasonable drying period with a rinse with 90+ % isopropyl to remove any remaining water. Shake well with rotating to help remove most of the alcohol and hang again - the alcohol will absorb any water it finds and still finish drying thoroughly and quickly. High percentage alcohol is also available at Walmart in the drugstore area. The higher the ambient temp., the quicker the drying (assuming a reasonably low ambient humidity).
. Worse to worse, you can start the rinsing process with warm tap water. Follow the steps for distilled water, and while it's hanging you can go out and get the distilled water and alchol and start the process over from the beginning when you get back. If you have reasonable mechanical skillz, you could disassemble the kbd to rinse it as you will get more thorough rinsing and drying and you can check that all the tea has been gotten rid of.
People with above moron level IQ are supposed to be able to learn from their mistakes.
Perhaps a toddler's sippy cup would help limit the spillage in the future.

You must be buying your equipment with OPM...
