Recycling 101: How Clean Do My Containers Need To Be?

You just finished a carton of yogurt and want to recycle the container. Do you need to wash it out first? And if so, how much effort is needed?

The answers: Yes—and a quick rinse will do.

Chicago used to advise that recycled containers simply be empty—no rinsing was necessary. But over the years, the city has modified its recommendation and now asks that residents empty their containers and give them “a little rinse,” said Department of Streets and Sanitation spokesperson Sara McGann.

On Thursday, Chicago launched its latest public service announcement for the city’s Blue Cart Recycling Program. The campaign, titled “It’s All You,” reminds residents about their role in improving Chicago’s recycling culture.

“The message of the campaign is simple: Each individual can make a tremendous impact on the success of the program by making recycling part of your everyday routine, just like brushing your teeth or getting your mail,” said DSS Commissioner Charles L. Williams in a press release. “When we recycle, our environment is protected and communities prosper, both health-wise and financially.”

During the campaign, residents will receive informational cards in the mail with reminders on recycling basics. The city also offers an online recycling guide, which includes a quiz to test your recycling knowledge.

One question asks whether empty yogurt cartons, peanut butter jars and milk jugs need to be spotless in order to be recycled. No, the city says – but they should be rinsed out.

“Usually a good swish of water or scrape of the spatula will do,” the city says. “Or wipe out the residue with a used napkin.”

The city has stricter requirements for certain types of recyclables like pizza boxes, however. Examples from the city’s online recycling quiz include the following guidelines:

  • Aluminum foil – “If it’s not clean, better to leave it out.”
  • Aerosol cans – “Must be completely empty so they don’t explode during recycling”
  • Cardboard – “No greasy cardboard”

The list also includes disposable coffee cups, which the city says are not recyclable because they have a plastic lining that can’t be separated at the recycling facility. That’s why the city recommends switching to a reusable coffee cup, which it says can help each person save half a tree every year.
