Our grandson (9 years old at the time) stayed with us one summer. When he left for Montana I cleaned our living room top to bottom. I found 7 sandwiches molding in g drawer in the end table. I had to use a razorblade scraper to get it all out. Then I used the bleach. I called him and asked about the sandwiches and his reply was *It was an experiment Grandma*. He is lucky there were 2500 miles between us.
