Type Cover 2 works by electricity. It doesn't have a digestive system to convert delicious food into energy, sadly. Maybe TypeCover 3
It is VERY tricky to clean the keyboard without being able to disassemble it. Assuming it bugs you that you are about to buy a new keyboard.
I would clean the keyboard using demilitarized liquid, such as fully distilled water.
Distilled water does not conduct electricity. However, you'll be mixing it with the soda as you try to dilute it. So, you'll need a lot of it. The problem is getting the water everywhere inside where the soda reached. Then I would leave the keyboard for 2 to 3 days for drying. putting it in a bag of rise will help the drying process as the rise grain will absorb the water and humility, and are large enough to not go in the device and cause another problem.
The problem we have, is that the keyboard circuitry is a membrane one.
Meaning you have 4 layers.
- First layer of printed circuit
- Second layer is a plane peace of plastic sheet with holes where the keys are.
- Third layer is a printed circuit.
Basically, the way it works is that you want the 2 layers of circuit to touch together to register for akey press. The second layer (the middle one of this sandwich) acts like a separator so that the 2 circuit does contact only when you do a key press.
Where is the fourth layer?
The fourth layer is a rubber domes which acts like spring to lift up the keys.
Liquid can penetrate on any of these layers. This is why I said that it would be much easier to clean if you can disassemble it, in which case you can use normal tap water to clean the keyboard as you'll be drying it easily with a nice cloth each part of the keyboard as you assemble it back.
