While cleaning our old apartment in our recent move, I discovered a cleaning product that I will never forget! We had many black marks on our walls, and our apartment manager had told us that they planned to paint the walls. Any dark marks would show through the paint, so we were asked to remove them. They suggested using Mr. Clean Magic Eraser. I figured it was worth a try and got one from the store.
I was absolutely amazed at how well the Magic Eraser worked! I wet the sponge, rubbed gently on the wall, and black crayon marks erased easily from the wall! It also worked on marker and furniture marks! I was quite impressed! I plan to keep one around the house from now on!
