Want a Clean Slate?

Clean your Clapperboardimages

After all these years we’ve got a clean slate.

In video production and filmmaking they usually hold a slate (clapboard) up in front of the camera to identify the scene. They “clap” the board of the clapboard after identifying the scene and the director shouts, “ACTION”.  Word has it that Clint Eastwood doesn’t yell action but says, “Whenever you’re ready.”

Anyway, for years we had dirty slates.  They never seemed to clean off the last scene’s information.

The slates are made of acrylic. So, last week, to celebrate Oktoberfest, we bought a new one.  We picked up the dry erase marker we’ve been using for years on the slates and when we went to wipe it off, we saw the same after image.  We couldn’t get it out with window cleaner, soap, green cleaner etc. etc.

Then we noticed that on the dry erase marker we’d used for years there was some fine print – “Indelible if used on clothing and porous materials.”

Aha! So we’d been using the wrong Dry Erase marker all these years.  Other dry erase markers, made by the same company with the exact same brand name had no such warning.

So, how do we salvage our brand new clapboard?  It turns out that “Goof Off” took the after image away completely.

HOWEVER, it will also dissolve the paint filling the etched words on the slate – “Director”, “PROD.” etc.  So be careful.  You may get a slate that’s cleaner than you wanted….which would be a refreshing change for Hollywood.

(We did contact Sanford, the maker of EXPO markers, to see if they still make the indelible on porous materials dry erase marker.  We’ll report back what they said.  Stay Tuned.)
