    Clean permanent marker off projector lens

    Some little bar steward has written the word 'poo' onto one of our projector lenses in permanent marker. i'm a little wary about using a solvent based cleaner to remove it as i'm unsure of what that would do to the lens coating (?)

    i'm not really sure what the best approach is. It's not really affecting picture quality, and i fear i could make it much worse if i damage the lens.

    at the same time it needs cleaning off though

    any ideas/previous experience would be much appreciated

    In the past I've used whiteboard cleaner to take ink off a projector lens. I'm pretty sure they're not coated with anything but it might be an idea to check before hand.

    it appears to have a two-tone metallic coating like a camera lens

    Re: Clean permanent marker off projector lens

    [slightly off topic] - did they think to write it on backwards so that it projected onto the screen properly??

    no. for some reason they felt they needed to write it upside-down. it doesn't project anyway

    You're right, it does sound wiered! I may have to try writing on a whiteboard with permanent marker to see what happens

    methanol, ethanol or isopropanol from the science dept works a treat on whiteboards.
    Depends on what the coating on the lens is as to whether is will dissolve it - check with the manufacturer

    Deerwood is right, the dry erase marker trick usually works a treat!

    Yup, thats how I shift it, good old dry wipe marker. Also deoderant is useful (also hair spray, but I aint in to hair spray, but have deoderant).
