Ok, so the other day I noticed my Pokewalker was missing. Evidentally, it got caught in the washing machien. This was bound to happen eventually, since I don't tend to remember to clean out my pockets after work. Eventually I found it in my mother's custody, not working. I snagged it back and got to work. It took a few days, but I DID get it working again, with my pokemon (a random event Remoraid, ironically. It just decided to join me that day when there was no pokemon in there) still intact along with items. Yay.

So, here's how to repair it if your pokewalker gets washed or dropped in water.

1.) Even if it's not wet externally, there's probably water inside and the hardware is wet. Don't panic. Just wrap it in something, so the water can start getting pulled into the external cloth.

I used my pocket, and later found my pocket to be wet from it. Lol.

2.) It won't start working right away, since there will still be moisture inside. You don't need to unscrew the device though, to dry it. One thing you can do, and what I did, is blow a bit into the sound thing at the bottom of the pokewalker every now and then, then find a way to balance the walker on a side for a bit. I'm using a rather thick bracelet to do this, which works perfectly.
this will allow further water to at least move away from the internal hardware.
Keep in mind to rotate the walker so anything under the infared light thing can seep out.

3.)If you abuse a laptop like I tend to, and it gets hot somewhat frequently, just stick the walker under the laptop (provided it has a built in stand. If not, put something there so there's some room between the laptop and the walker.) so the heat of the laptop can pass into the walker for about a day or two. This will evaporate any leftover water molecules and dry the inside of the walker.

4.) After a few days, try holding down the center button of the walker to turn it on. Chances are, now it'll start up again and still be functional.

Hopefully this helps anyone else who will likely have the same problem. ^^
