So I wanted to give the dishwasher a try, and without taking each key apart -- patience has its limits!
It worked great for me, and just requires some caution.
- If possible, take the case apart. This will help the dirt, then the water, go away.
- Allow to dry completely. It will take days. Failing to do it may cause shorts and harm your keyboard and your computer!
- Wash at mild temperature.
In any case, please use your common sense; do it at your own risk; in case of doubt, don't do it. (Well, you're on instructables.com)
Step 1: Needed Stuff
I needed a TX5 (small hex) and a PH0 (small Phillips), from my warranty voiding kit.
And important: You need a second keyboard, to be used while the first one is drying (it takes days!). Otherwise, the temptation to use the still wet one may be too high.
Optionally an USB hub is useful to lower the risk of harming your computer when testing the keyboard at the end of the process.
