I just put my whole keyboard into the dishwasher with some regular dish soap. (Palmolive) Then, when that gets done I bungie strap it in between two dry pillows and stick it in the clothes dryer for an hour or so. Comes out clean and perfect every time as long as you make sure all the soap is gone. Water in and of itself won't damage electronics, it takes water and electricity if your keyboard is either wet with no current or dry with current, it's safe.
