This could be bad or just annoying depending on how you wiped it down.

There should be a monitoring utility that will let you choose settings and see what the keyboard batteries are. You should be able to see if it is finding the keyboard. This should also be where you can unlock the keyboard or use a security code.

There should also be a reset button or connect button along the bottom of the keyboard as well as one on the antenna. Press the antenna first then the keyboard button. The lights on the antenna should flash. As well when you press caps lock or numlock a light should change on the antenna.

One thing to check is that the antenna connector is plugged in. On mine it comes loose just by walking by it. Just needs a push to make sure its inserted and hasn't come loose.

If none of those get your keyboard back then it may be that you damaged the keyboard.I would try leaving it near a heating grate so that the warm air blows over it for a day or so. It may be enough to dry out the inside enough to work. Past that the keyboard may be repairable but you would have to find someone to fix it and you would need to check that cost against replacement.
