Why does our unit smell worse on the second day of a hot weekend?
We rented a standard portable toilet for a big backyard party Saturday and Sunday. The rental company delivered and serviced it Friday afternoon, so it was fresh. Saturday morning it was fine, but by Sunday afternoon the smell was really strong, even with the door closed. It was a hot weekend, probably 85 degrees both days. We had about 40 people over, mostly Saturday evening with a barbecue and drinks, but a smaller group Sunday. The unit is on level grass, and the truck had no problem getting to the spot for delivery. I thought a standard unit would last the weekend without smelling. Is the heat the main reason it got bad so fast? Does a weekend party need a different service schedule than a single-day event?
