Tried 10 different things to clean the whiteboard in the kitchen. Besides the "corn spray" from canning the other day, the "wipe-off" ink would not wipe off!
Saw a tip online to use peanut butter. Worked like a charm. Smear a little on, scrub it around. Wipe off. Lightly wash with warm water on washcloth. Used an extremely light washing of Murphy's oil soap.
