I read this on Tuesday, and what is the first thing I do when getting to the Fortress?... I try to press some material formally used as a boat cover. Yep, sticky, dirty mess!!! So got my magic eraser out and scrubbed, it worked, but still had to use the end of my "wooden iron" to gently rub off the heavy areas, then go back and reuse the eraser.
Gotta love this board. Great timing!
