Bread
Do you have some slices of old and chewy (white) bread left over? You can roll them up into a ball. As a result, you have made an eraser that removes stains from walls and kitchen cupboards. They used to use moist breadcrumbs to remove pencil marks from paper. The gluten in the bread absorbs the stains. Make sure you dab with it and don’t rub it. Rubbing can make it worse!
