You can easily solve the fogging issue with a simple spray on liquid. Go to the dollar store and you may find a small spray bottle that has anti-fog in it. I remember this being sold by the buckets at the motor show to prevent the fogging inside the car. Spray it on and wipe. It will last for about a day or two but long enough to let you play.
Alternatively, you can use a very diluted (small drops) of handwash or soap you can find and wipe it on the surface. Wipe with dry cloth or damp to remove any haze. The soap film will repell any moisture from attaching to the surface.
