Ugh. Not much of a computer without a keyboard. If you already have an ST keyboard that doesn't work right take the keyboard case off top and bottom and immerse the innards in mild dishsoap and warm water in a sink. Rinse it out well with cold water. Shake it out like a wet umbrella until the standing water is gone and lean it up against the wall to dry. You could also use a hair dryer. let it sit overnight and try it in the morning without the case on. If it works you can put the case back on the keyboard.
