Looks like it would do fine to me. You would want to clean it with alcohol if you ran it through the wash, to avoid corrosion, but otherwise it would be fine.

I think it would be tough to break the board, so mechanically the worry would be bending some pins such that they shorted. I have no idea what the ESD sensitivity of the parts is, but if it's something your going to walk around with in your pocket, that's something to think about. I'd probably use some heatshrink tubing on it.
