erasers can be hit or miss. Mine worked at 1st but eventually couldn't get stuff off without making a huge mess.
I end up just spitting on the boards and using my white tshirt to clean it. I didn't care. Clock was ticking and clothes can be washed. Plus its plain tshirt I can go to target and buy a 6 pack. I have the same attitude going in, 3 weeks from now.
