After a little research, I came across this post. It details two different ways to clean eReader screens. One for E-Ink screens and one for LCD screens.

The Coles notes version for E-Ink screens:

Use a dry cloth or dampen a cloth with water (microfiber preferred).
Do not apply water directly.
Carefully wipe screen with cloth and allow to dry before using.

The Coles notes version for LCD screens:

Microfiber cloth
LCD solution or mix (50-50) isopropyl alcohol and distilled water (not tap water!)
Moisten cloth, wipe and dry before use.

So one recommends water and one recommends against water. PRS-650 is a touch screen, but is E-Ink display. So which way is better? It turns out the PRS-650 does not have a special layer on top of the E-Ink display like it's predecessor (it uses light sources firing over the surface to tell when there is something touching it, or just over it). More info here. So this leads me to believe it should be treated like an E-Ink display and cleaned accordingly.
