Thought I would share this in here. Here are some tips for a cheap, but effective, dry erase board. Most of you probably already know you can by a 4′ x 8′ sheet of “shower board” at your local hardware store. But after a while the markers won’t erase and usually after a few months your board is almost ruined. Next time you buy a piece, try applying car wax to it before you put it on the wall. These helps make the surface less porous and keeps markers from staining it. Use green or red dry erase markers. The lighter colors seem to erase completely compared to blue or black. Last tip, buy a micro-fiber towel that is used for car detailing to erase with. It is great at taking the marker off the board and its not as harsh as paper towels.
