This is a cool thing you can do to remove permanent marker stains from your porcelain dolls, plates, and any other items that are made out of porcelain.
Put regular toothpaste on the part where your porcelain item is stained with permanent marker. Only use a moderate amount on your porcelain item.
Use a damp paper towel or cloth to clean off permanent marker stains. You really don't want to use an extremely wet cloth to clean off permanent marker.
Gently wipe off permanent marker. When you are finished and wiped off all toothpaste from items, your porcelain item or items are free and clear from all marks and stains.
