Download Caring for Reusable Bags [fact sheet]
While reusable bags are a good, eco-friendly way to pack groceries, household items and clothing from your favorite stores or farmer’s markets, the reality is that reusable bags are not cleaned on a regular basis, particularly the ones used to carry groceries.
Organizing Reusable Bags
Two ways to reduce the risk of bacterial or mold growth are to designate separate bags for meats, poultry, fresh produce, clothing, and household cleaners and wash them on a regular basis. Labeling bags with permanent markers for each use is a great way to keep them organized.
It is also recommended to avoid carrying dirty items or trash in a reusable bag that you plan to use for food at the farmers’ market or grocery store. Always wash bags if you plan to change their use or as mentioned above, designate bags for certain activities and keep them that way.
Cleaning Reusable Bags
All reusable grocery bags can be washed; some just need a little gentler care than others. Check the care labels on the bags and follow the directions. If the bag doesn’t have a care label, follow these instructions:
Woven or non-woven polypropylene: Machine wash on a gentle cycle with soap and cold water or hand wash in cold water. Line dry.
Nylon or polyester: Hand wash in warm water and soap. Turn inside out. Line dry.
Bamboo or hemp: Hand or machine wash on a gentle cycle with mild laundry detergent. Machine dry on low or line dry.
Cotton: Machine wash with hot water and laundry detergent. Machine or line dry.
Insulated bags: Hand wash in warm water and soap or wipe with sanitizing wipes, pay particular attention to the seams. Line dry.
Storing Reusable Bags
Make certain the bags are completely dry after using or washing and before storing. Avoid storing your bags in the trunk of your car. This dark, warm and often humid environment can promote bacterial and mold growth, particularly in the summer.
Reusable bags can last a long time with care, but they don’t last forever with repeated use and washing. Bags that are too dirty, torn and beyond repair are worth replacing. Remember the tried-and-true food safety motto:
“When in doubt, throw it out.”
