Reusable shopping bags are one of the simplest ways to cut down on single-use plastic. If you’ve made the switch, you’re already making a small change that’s better for the planet.
But reusing your bags also means taking care of them. Over time, they can collect food spills, crumbs, and odors, so giving them an occasional wash helps keep them clean and ready for every grocery trip.
Plus, learning how to wash reusable shopping bags is actually pretty easy since most are made with material that doesn’t need much care. Just a bit of timely cleaning with a gentle detergent and proper storage.
Why do you need to wash reusable shopping bags?
Most reusable bags are used week after week without much thought. But every grocery trip leaves behind a little dirt, moisture, or food residue that can build up over time.
Cleaning your reusable bags regularly helps:
-
Remove food spills and stains.
-
Prevent unpleasant odors.
-
Reduce bacteria from raw meat or produce.
-
Protect fresh groceries from cross-contamination.
-
Help reusable bags last longer.
Even if your bags look clean, it's still a good idea to wash them regularly, especially after carrying meat, seafood, eggs, or anything that leaks.

Here is how to wash shopping bags made of nylon or polyester:
-
Turn the bag inside out.
-
Hand wash with warm water and mild detergent.
-
Rinse thoroughly.
-
Hang or line dry completely.

Woven or non-woven polypropylene bags
These lightweight reusable grocery bags are made from a type of plastic that's often produced using recycled materials. Most can be machine washed, making them easy to clean after regular grocery trips.
-
Shake out crumbs and debris.
-
Machine wash on a gentle cycle with cold water and detergent.
-
You can also hand wash with mild soap and water.
-
Line dry completely before using again.
-
Bamboo or hemp bags
Bamboo or hemp bags are made with natural and biodegradable fibers. While these bags are sturdy, machine washing a tote bag made of bamboo with a regular cycle can cause the natural fibers to swell, warp, or weaken.
Here’s what you need to do instead:
-
Shake out loose dirt.
-
Hand wash gently.
-
Use a mild laundry detergent.
-
Machine dry on low or line dry.
If you need to machine wash, always use the gentle cycle.

Insulated bags
Insulated grocery bags are generally made with polyester and then coated with a layer of thermal film. These bags are designed to help keep groceries hot or cold, but they shouldn't usually be tossed into the washing machine because the insulated lining can become damaged.
Here’s how to wash reusable shopping bags that have insulation:
-
Hand wash with warm water and mild soap.
-
Pay extra attention to the seams where spills can collect.
-
You can also wipe the inside with disinfecting or antibacterial wipes.
-
Leave the bag open and line dry completely.
Tip: If your reusable bag has printed logos or graphics, wash it with cold water for the first few washes to prevent the print from bleeding.
