I cross posted this to the Entertainment board as well.

Yesterday, my son had some friends over to watch a movie for his 10th birthday. Apparently, some kid thought it was completely okay to throw a slice of pizza at my screen.

Anyone know how to get pizza sauce off a screen? How about getting my rage to come down? I'll take suggestions for that also.

What kind of screen? How textured is it? And is it more white or the silver reflective stuff?

I'd start with just warm water and a sponge. upgrade to dish soap if that doesn't work. Wipe with a sponge and have towel underneath to catch the water dripping down the screen.

Tell your kid that pizza thrower is not allowed back at your house, and that he can't hang out with him outside of school. keep bad influences away early and often.

Most projector screens can be cleaned with warm soapy water. When in doubt, check the manufacturers recommendations.
