Same procedure can be used on whiteboards when enthusiastic professors use permanent markers on whiteboards.

NEVER SCRUB 1) Spray the WD-40 on the rag...enough that it is wet not dripping 2) Then you dab the screen that has the ink on it 3) Let the WD-40 breakdown the ink a bit 4) Then dab off with a clean rag 5) Then repeat steps 1 - 4 until the ink is removed 6) WD-40 is oily so it will leave a shiny area on the screen 7) While the screen is wet with WD-40 use regular rubbing alcohol in the same manner as you used the WD-40 in Steps 1-4 until the screen texture comes back to normal. Your screen should like good as new...but be patient it takes time for the liquids to breakdown the ink. When you're done you will notice where you just cleaned the area will be a little brighter than the rest of the screen...how noticeable this will be will depend on the age of your screen but eventually the clean area will weather in to matching the rest of the screen. Hope this helps John and others with a similar problem. -deg deg farrelly, Media Librarian Arizona State University Libraries Hayden Library C1H1 P.O.

VIDEOLIB is intended to encourage the broad and lively discussion of issues relating to the selection, evaluation, acquisition,bibliographic control, preservation, and use of current and evolving video formats in libraries and related institutions. It is hoped that the list will serve as an effective working tool for video librarians, as well as a channel of communication between libraries,educational institutions, and video producers and distributors.
