I watched my SIL take a black permanent marker to her countertops and floors and then tried using your average cleaner to clean it and it would do a thing. She dabbed some of this stuff on a rag and wiped and it DISAPPEARED within SECONDS!
Crazy stuff I tell you. And it's suppose to be totally natural.
