i love dry erase boards, especially when they are new. i also love ye olden faithful boards of slate that require squeaky chalk and puffy erasers. but those pristine white boards call out to me. the best part? they are snazzy and a snap to clean! compare along with me.
chalkboard: a chokey dust covering the board in filmy white or yellow. haul out the sponge, make sure it's good and wet, and mop over every bit of the board. if you want to keep your board perfectly clean, you would need to go through this procedure every time you use it. (and don't forget to clap the erasers outside to get out as much chalk dust as you can, but once used, they will never be pure again.)
whiteboard: having used your especial markers, the board is filled with many colors - but too heavy on the black! oh, no!
