|Keyboards do get very dusty when left set up in the home or studio. They are also in danger of having liquids spilt on them resulting in expensive repair bills. Keycovers are designed to overcome both of these problems.
The translucent vinyl used to make Keycovers is the ideal material. It is solid, not woven, and so cannot allow liquids to pass through. Being translucent, you can easily see if the power has inadvertently been left on (causing the keyboard to overheat). All edges are taped and stitched for long life and the vinyl material is treated with an anti-static agent that keeps dust away.
