Apple Keyboard may be broken.. Any way to be sure? Well, I "cleaned" my Apple keyboard (2010 model). I used a wet rag to clean the well-used keys. It looks great but it doesn't work. I hate to toss it if I can fix it. Is it possible that I've pressed a combination that has deactivated the keyboard?

I am traveling but have the kb with me. Is there any kind of hardware test I can perform. I know the device has power as I can plug in a mouse to the USB port and the mouse works.

Thanks for any tips.
Once a keyboard trace has been damaged by water, it's practically impossible to fix them.  You're better off buying a new keyboard.

It's not the best news, but once a keyboard has been damaged by liquid, there's very little chance they will work again.

For cleaning your keyboard, I'd recommend isopropyl alcohol pads.
