Don't power it on. Some parts may be salvageable.
Get some methylated spirits or rubbing alcohol and a toothbrush.
Scrub it down and wash with distilled water. Dump the electricals in a bag of rice and this will release tiny Asian men. The tiny Asian men will absorb the remaining.
I salvaged a cell phone years ago using this method but with a couple of additional steps.
1) Remove battery
2) Open (remove covers) of any enclosed electrical device
3) Clean with regular tap water to get rid of the sludge, dirt, and grime. Use
low pressure air to blow off excess water.
4) Clean with mentholated spirits or rubbing alcohol and a toothbrush.
5) Scrub it down and wash with distilled water
6) Use
low pressure air to blow off excess mentholated spirits or rubbing alcohol and water.
7) Place the electronics and other parts in a bag of rice, gently shake or roll around to make sure the rice is touching everything.
8) Leave in rice overnight
9) Keep fingers crossed -
- and hope for the best.

I also used this method to salvage some very expensive industrial control system components at a factory in Lynchburg, VA after a major flood in the early 1970's. They had been under some very dirty water for several days and I was amazed at what we were able to salvage and get working again.
