Old Whiteboard Saved From Linda Hartwig: "Our second hand whiteboard was heading to the trash heap when we decided to give one last try at getting it clean. We had tried everything from WB cleaner to WD40 and it was still in bad shape. A co-worker brought in a car buffer and some car polish. We gave it a good Windexing after the polish had cleaned it off and WOW it now looks good as new. We used car polish not car wax. I would not have done this but all other methods had failed and I did not want to buy a new board."
