I have built a custom application for my tablet that I am going to be putting into a friends store on the wall to help people locate products. The problem is that a ton of people will be using the tablet on a daily basis, and we all know not everyone has clean fingers which brings up my questions. 1. Is there something that should be put over the screen to help protect it, and if so what? 2. Is there something that should be used on cleaning the tablet screen on a daily/weekly basis to keep the touch working great 3. Can you think of anything else that I should be worried about (I already have a secure way to mount it to the wall so nobody can steal it).
