You are going to laugh when I tell you this story. A longtime friend was moving out of her rental apartment and she wanted me to check it out. I asked did you hang and pictures, yes.......I did not have any DAB, no I grabbed the old white tooth paste container. I went thru checked all the walls and put the toothpaste in the tiny holes and smoothed it out with my fingers. She laughed as she could smell it but it dried before we left. Then I said do you have a cell phone that takes pictures.......yes she did and she got all her deposit back.........
