How to Clean and Care for Reusable Shopping Bags with Eco-Friendly Detergent

Reusable shopping bags have become a staple in eco-conscious households, helping to cut down on single-use plastic waste. But how often do you actually wash them? Many people overlook the fact that these bags can harbor bacteria, food residue, and even mold if not cleaned regularly. A study from the University of Arizona and Loma Linda University found that 99% of reusable bags tested contained bacteria, with E. coli present in 8% of them. That’s a good reason to add bag washing to your routine.

The good news? Cleaning your reusable bags is simple and can be done with eco-friendly laundry products that are gentle on fabrics and the planet. In this guide, we’ll walk you through the best methods for washing different types of reusable bags, from canvas totes to insulated coolers, using sustainable detergent strips. We’ll also share tips for drying and storing them to keep them fresh for your next grocery run.

Why You Should Wash Reusable Shopping Bags Regularly

Reusable bags come into contact with raw meat, produce, and other food items, which can transfer bacteria and odors. If you use the same bag for groceries and then for gym clothes or books, you’re spreading germs. Washing them every few weeks—or after carrying raw meat or leaky items—helps prevent cross-contamination and keeps your bags looking clean.

Beyond hygiene, regular washing extends the life of your bags. Dirt and oils can break down fabric fibers over time, leading to tears or fraying. By using a gentle, eco-friendly detergent like Tru Earth Laundry Detergent, you can remove grime without harsh chemicals that weaken the material. Plus, switching to detergent strips reduces plastic waste from bulky liquid bottles.

• Wash bags after carrying raw meat, fish, or leaky produce.
• Set a reminder to wash all bags at least once a month.
• Check care labels—some bags are machine-washable, others are hand-wash only.

Choosing the Right Eco-Friendly Detergent for Bag Care

Not all detergents are created equal when it comes to cleaning reusable bags. You want a product that is tough on stains and bacteria but gentle on fabrics and the environment. Traditional liquid detergents often come in plastic jugs and contain phosphates, optical brighteners, and synthetic fragrances that can linger in fabrics and irritate skin.

Eco-friendly detergent strips, like those from Tru Earth, are a perfect choice. They are ultra-concentrated, plastic-free, and dissolve completely in both hot and cold water. For a thorough clean, use a full strip for a standard load of bags. If you have heavily soiled bags (e.g., from raw chicken juice), pre-treat stains with a dab of the dissolved strip solution before washing. The Tru Earth Platinum Laundry Detergent - 384 Strips offers a bulk supply that’s ideal for regular bag washing.

• Use one detergent strip per load for standard bag cleaning.
• For tough stains, dissolve a strip in water and apply directly.
• Avoid fabric softeners—they can leave residue on bags and reduce absorbency.

Step-by-Step Guide: Washing Different Types of Reusable Bags

Canvas and cotton totes: These are usually machine-washable. Turn them inside out to dislodge crumbs and dirt. Wash on a gentle cycle with cold water and a Tru Earth laundry strip. Add a half-cup of white vinegar to the rinse cycle to neutralize odors. Air-dry completely to prevent mildew.

Insulated cooler bags: These often have a waterproof lining that can’t handle high heat. Wipe the interior with a cloth dipped in a solution of water and dissolved detergent strip. For a deeper clean, hand-wash with cool water and a strip, then hang to dry. Never machine-dry insulated bags.

Polypropylene (non-woven) bags: Common in grocery stores, these are durable but can melt in high heat. Machine-wash on a gentle cycle with cold water and a detergent strip. Air-dry only. To freshen between washes, spray with a mixture of water and a few drops of Tru Earth Multi-Surface Cleaner - Lemon Fresh / 8 Sheets.

• Always check the care tag before washing.
• Use a mesh laundry bag for small or delicate bags to prevent snags.
• Avoid bleach—it can damage fabrics and leave harmful residues.

Tips for Drying and Storing Reusable Bags

Proper drying is crucial to prevent mold and odors. After washing, shake out excess water and hang bags in a well-ventilated area or outdoors in the sun. Sunlight has natural antibacterial properties and helps bleach stains. Avoid using a dryer for most bags, as heat can shrink or warp materials.

Store your clean bags in a dry, breathable place. Avoid stuffing them into a tight drawer or car trunk while damp. Many people keep a few bags in the car for impromptu shopping—just make sure they are completely dry first. To save space, fold or roll them neatly. Consider using a dedicated bag caddy or hanging organizer.

• Air-dry bags inside out to speed up drying.
• Store bags in a cool, dry area away from direct sunlight to prevent fading.
• Rotate your bag stash to distribute wear evenly.

How to Freshen Bags Between Washes

If your bags aren’t visibly dirty but have a lingering smell from onions or spices, you can freshen them without a full wash. Sprinkle baking soda inside, let it sit for a few hours, then shake it out. Alternatively, wipe the interior with a cloth dampened with a diluted Tru Earth Multi-Surface Cleaner - Lemon Fresh / 8 Sheets solution.

For a quick deodorizing boost, place a few Tru Earth Reusable Wool Dryer Balls - 4 Pack in the bag overnight—they naturally absorb odors. You can also spritz the bag with a mix of water and a few drops of essential oil (like lavender or tea tree) for a pleasant scent. Just avoid oversaturating the fabric.

• Use baking soda as a natural deodorizer.
• Keep a dryer ball in each bag to absorb moisture and smells.
• Avoid using chemical air fresheners—they can transfer to food.

Caring for your reusable shopping bags doesn’t have to be a chore. With a simple routine and eco-friendly products like Tru Earth laundry strips and multi-surface cleaner, you can keep your bags clean, fresh, and safe for every trip to the store. Regular washing not only protects your health but also extends the life of your bags, making your sustainable choice even more impactful.
