Step 5: Clean Keys
The next step is to give your keys a soak in some dish soap (or other mild detergent) and warm water. Fill your cup or container and drop in your keys.
I let my keys soak for about an hour.
Some of your larger keys may have one or several metal guide bars on their underside. These bars slide into slots on your keyboard, so make sure not to bend the bars or their slots on your computer.
