Cleaning and Stain Removal - Stinky Roll-Off Box

How do I clean an animal decomposition-type smell from a roll-off box?

I got this in my driveway for some landscaping waste. After the driver left I noticed that it smells like a rendering plant or the back lot at the slaughterhouse in July.

I used car wash concentrate, water and a deck brush to wash it down but it still smells just as bad. I don't see anything rotting and it's not attracting a lot of flies or anything yet. There is some dirt on it, on the outside that seems to stink but I do not want to just wash the stinky stuff onto my driveway. The box was completely dry when delivered.

The mere thought of breathing deeply while shoveling dirt & rocks into it for a couple of days makes me want to wretch.

Suggestions? Thanks.

Never mind. I called the hauler and they said they will replace it with something a little rosier.

Good that they are willing to work with ya. Always wondered if they clean those in between or just keep slamming them around.
