How do you dispose of old baking powder?

1. Check the expiration date: If the baking powder is expired, it's best to discard it. Expired baking powder may not be effective as a leavening agent and could affect the taste and quality of your baked goods.

2. Empty the contents: Pour the remaining baking powder from the container into a sealable plastic bag or wastepaper basket lined with a plastic bag. Avoid pouring it directly into the sink or garbage disposal, as baking powder can react with water and cause fizzing or clogging.

3. Seal the bag: Close the plastic bag securely to prevent any baking powder from spilling out.

4. Dispose of the bag: Discard the sealed plastic bag in your household trash. Because baking powder is non-toxic and biodegradable, it can safely go in the general waste.

5. Rinse the container: If you plan to recycle or reuse the baking powder container, rinse it thoroughly with warm water to remove any residue. Let it dry completely before recycling or storing it.

6. Follow any local guidelines: Some areas may have specific guidelines or restrictions on disposing of household chemicals. Check with your local waste management or recycling center for any additional instructions or requirements.

Remember, it's important to properly dispose of old or expired baking powder to avoid any potential health or safety hazards.
