One of the items was a clear heavy plastic sheet we keep on the floor under the cage.
We washed one side then let it dry a little. Later, we flipped it over and washed the other side
and let it dry. Then we packed it all up and put it in the POD for the move.
Later that day we noticed two dark patches in the lawn where the plastic had been. The next day they were completely brown and the lawn was dead. I'd heard of doing this with black plastic, but was surprised how "effective" it was at killing the lawn with a clear sheet.
