Last saturday the sun was shining into my room and it nicely enhanced the gross state my keyboard (a wireless Logitech natural keyboard) was in, after years of typing, which must be zillions of key presses (and having breakfast while reading my daily portion of websites):

At that point I thought that either I would go out and buy a new one, or I'd try something radical. I remembered from childhood that you can put LEGO bricks into a washing machine if you put them inside a pillow cover, and I planned on doing something similar with the keys of the keyboard. While googling if that wouldn't erase the print on the keys, I actually found a guy that used the dishwasher to clean the keyboard.

This could be a bit tricky, but given the state it was in, I thought 'oh well, why not'.

So, after removing the batteries and taking off the wrist pad, I put it in the washer:

I just tossed it in the washer with the rest of the dishes; upside down so the keys would get the most thorough treatment. I added a normal 3-in-1 cleaning tablet, and had it run at the 50 degrees Celsius 2-hour Economy program.

When it was finished, I took out the keyboard, and it was completely soaked:

I poored out the water, took out all the keys so the keyboard would dry more easily, and left it to dry:

After 5 days (it may look dry, but you have to make sure all the inner parts have dried too), I put all the keys back in. This was an interesting puzzle; I had pictures of the layout but I managed to put in everything without looking at them :-). I inserted the batteries and voila, it worked out of the box!

The end result:

So, YES, you can put a wireless keyboard in the dishwasher!

P.S. I expected the stickers on the back to come off, but although they have a few small bubbles now, they came out fine.
