Ipod touch with gray screen???

I accidently put my Ipod touch in the washing machine and I put it in rice like most people say to do, waited a couple days, plugged it into my laptop, the screen lit up (Didn't show the usual earth background or time at all) the screen kept changing colors then it became different shades gray and I could see some spot that I think are water but not sure. My friend said I should just wait, should I?
