I desperately need your help. One of our teachers accidentally wrote on an overhead projection screen with a whiteboard marker.
OOPS!!! How do we clean it? I have whiteboard cleaning solution, but it states for non-porous surfaces, so I am not game to use that.
Thanks,
Carol.
OHP screen cleaning????
Re: OHP screen cleaning????
Hi Carol,
Is it the white screen that the picture is projected to or the screen on the machine?
The whiteboard cleaning solution should work on the 'machine' screen but the other would be different.
I would try 'grafitti' remover. It works by first letting the solution soak into the writing, then it can be cleaned off. Do not rub; that just spreads it.
But think about it before you decide.
Check out the timetable and see when the offending teacher is free, go and get him/her. Then give him/her the solutions and say, "Go for it."
Hopefully it would stop him/her ever doing it again!

Metho. Works every time.

I think I will go with the metho. We don't have grafitti remover anyway, but plenty of metho.
Thankyou both so much.
Carol.

Eucalyptus Oil works a treat!!
Re: OHP screen cleaning????
If you're not into using chemicals unless you have to, there are these sponges available. They are called "Amazing Eraser" or something like that.(there's a few different brands available)They are sold at any supermarket. They are great for any texta/graffitti/lead pencil etc removal, and you just wet them with water. I try to have one when checking a room after a prac, because they will remove most graffitti, and it gets the job done there and then. A word of warning though, they actually disintergrate as you use it(not instantly) so I use a corner at a time. A great little time saver. I also use them to get marks off the beakers(students writing stuff with pens etc) as I am loading the dishwasher, as a lot of those marks don't come off otherwise.
