How To Clean Your Reusable Bags, Because They Probably Need It

ByBeaver Maids

Reusable bags are a fantastic way to reduce plastic waste and contribute to a greener planet. But let’s be honest—how often do you actually clean them? If you’re like most people, the answer is probably never or rarely.

Think about it: These bags carry everything from fresh produce to raw meat, leaky containers, and even gym clothes. Over time, they can become a breeding ground for bacteria, food residue, and unpleasant odors.

If you’ve been neglecting your reusable bags, don’t worry—we’ve got you covered. Here’s a complete guide on how to clean them properly, ensuring they stay fresh, safe, and ready for your next shopping trip.

Why You Should Clean Your Reusable Bags

Before diving into the cleaning methods, let’s talk about why it’s important:

  • Bacteria buildup: Studies have found that reusable bags can harbor harmful bacteria like E. coli and salmonella if not cleaned regularly.
  • Cross-contamination: Carrying raw meat, dairy, or unwashed veggies in the same bag without cleaning can spread germs to other items.
  • Odors and stains: Lingering food smells and spills can make your bags unpleasant to use.
  • Longevity: Proper cleaning helps extend the lifespan of your bags, so you get more use out of them.

Now that you’re convinced, let’s get into the cleaning process!

How to Clean Different Types of Reusable Bags

Not all reusable bags are made the same, so cleaning methods vary depending on the material. Here’s how to tackle each type:

1. Fabric Bags (Cotton, Canvas, Polyester)

These are the most common and usually machine-washable.

Steps:

  • Check the care label – Some bags have specific washing instructions.
  • Empty and shake out crumbs – Remove any debris before washing.
  • Pre-treat stains – Use a stain remover or dab with a mixture of baking soda and water.
  • Machine wash – Use cold or warm water with mild detergent. Avoid bleach, as it can weaken fibers.
  • Air dry – Tumble drying can shrink or damage fabric, so hang dry instead.

Pro Tip: Wash fabric bags after every few uses, especially if you carry meat or perishables.

2. Nylon or Polypropylene Bags (Foldable Shopping Bags)

These lightweight bags are often water-resistant but need regular cleaning.

Steps:

  • Wipe down with disinfectant wipes – Quick and easy for light cleaning.
  • Hand wash – Use warm soapy water and a sponge or soft brush to scrub away grime.
  • Rinse thoroughly – Ensure no soap residue remains.
  • Hang to dry – Avoid direct heat, which can warp the material.

Pro Tip: For stubborn odors, spray with a vinegar-water solution (1:1 ratio) and let it air out.

3. Insulated Bags (For Groceries or Meal Delivery)

These often have a lining that needs extra attention.

Steps:

  • Wipe interior with a disinfecting cloth – Target spills and sticky spots.
  • Use mild soap and water – Scrub gently, then rinse.
  • Deodorize with baking soda – Sprinkle inside, let sit for 15 minutes, then wipe clean.
  • Air dry completely – Moisture trapped inside can lead to mold.

Pro Tip: Avoid submerging insulated bags in water, as it can damage the thermal lining.

4. Leather or Faux Leather Bags

These require gentler care to maintain their appearance.

Steps:

  • Dust off debris – Use a soft brush or dry cloth.
  • Spot clean with a damp cloth – Use a mild soap solution for stains.
  • Condition leather (if real) – Apply a leather conditioner to prevent cracking.
  • Air dry away from sunlight – Prevents fading and drying out.

Pro Tip: Never machine wash leather or faux leather bags—it can ruin the material.

How Often Should You Clean Them?

  • After carrying raw meat, fish, or dairy: Clean immediately to prevent bacteria growth.
  • Every 1-2 weeks for regular use: If you use them frequently for groceries.
  • Monthly for light use: If you only use them occasionally.

Bonus Tips for Keeping Bags Fresh

  • Designate bags for specific uses (e.g., one for produce, one for meats).
  • Store bags in a dry, ventilated area to prevent mold and odors.
  • Keep a few spare bags so you can rotate while others are being cleaned.

Final Thoughts

Cleaning your reusable bags might seem like a small task, but it makes a big difference in hygiene and longevity. A few minutes of care can keep your bags fresh, safe, and ready for many more eco-friendly shopping trips.

So, next time you unpack your groceries, take a moment to toss those bags in the wash or give them a quick wipe-down. Your future self (and your groceries) will thank you!
