How to clean & prevent stickiness on hard plastic of mouse, in spite of no rubber coating
Product (originally available in white, now in blue only):
Sharing original link so that one can see its construction & materials and lack of rubbery stuff to cause this.
Also, all it has done recently is sit idle on top of the top shelf (that got dusty) gathering dust, as I was using a trackpad. I was expecting dust to be easy to just wipe off with a dry & wet cloth (in spite of humidity) but was not expecting sticky grime on it that would not wipe off with moist cloth.
This is typical of tech items (as in linked threads) with rubbery surface or coating but this was a simple hard plastic, smooth surface.
How to clean this, and prevent future build up?
