Most people think of the washing machine as a place for clothes, towels, and bed sheets — but it’s capable of much more. Hidden in plain sight are dozens of everyday items quietly harboring dirt, oils, and bacteria. By washing them regularly, you not only save time but also make your home cleaner, fresher, and healthier. Here are seven surprising things you can safely toss into your washing machine — and a few tips for doing it the right way.

1. Oven Gloves and Dishcloths

Few items get as dirty as the fabrics used in the kitchen. Oven gloves, dishcloths, and pot holders pick up food residue, grease, and bacteria from constant handling. Experts recommend washing them once a week in hot water — ideally at 60°C (140°F) — with your regular detergent. Adding a tablespoon of baking soda helps eliminate odors and cut through tough grime. Avoid fabric softeners, as they can reduce absorbency.

2. Microfiber Mops and Cleaning Cloths

Your cleaning tools clean everything else — but when was the last time you cleaned them? Microfiber cloths and mop heads trap dust, dirt, and germs deep within their fibers. If not washed regularly, they can end up spreading bacteria instead of removing it. Wash them separately from lint-producing fabrics at 60°C (140°F), and skip the softener so the microfibers keep their electrostatic cleaning power. Air-drying is best to preserve their texture.

3. Canvas and Reusable Tote Bags

Reusable shopping bags might help the environment, but they also collect crumbs, food stains, and sometimes even bacteria from raw foods. Turn them inside out, place them inside a pillowcase, and wash on a gentle 30–40°C (86–104°F) cycle. Use mild detergent and avoid the dryer, as heat can cause shrinkage. Airdrying helps them last longer — and keeps them smelling fresh.

4. Shower Curtains and Bath Mats

Bathrooms are warm, moist environments — ideal for mold and mildew. Fabric or plastic shower curtains can develop a subtle layer of grime, while bath mats trap water and bacteria from wet feet. Wash both together in warm water (40°C / 104°F) with your usual detergent and add half a cup of white vinegar to kill mildew and neutralize odors. Dry bath mats thoroughly before use to prevent mold from returning.

5. Stuffed Animals and Comforters

Teddy bears and comforters can accumulate dust, allergens, and even mites over time — especially if they’re loved daily. Wash these delicate items on a gentle cycle at 30–40°C (86–104°F) using mild detergent. Place stuffed animals inside a mesh laundry bag or pillowcase to protect them. Always air-dry toys and comforters to preserve their shape and softness.

6. Sneakers and Sports Gear

After workouts or outdoor adventures, sneakers, caps, and shin guards can smell less than fresh. Remove the insoles and laces, place everything in a pillowcase or laundry bag, and wash at 30°C (86°F) with mild detergent. Avoid high spin cycles or the dryer, as heat and tumbling can warp the shape of the shoes. Stuffing sneakers with paper towels afterward helps them dry evenly.

7. Pet Accessories

If you have pets, don’t forget their world of washable gear — from leashes and collars to soft toys and small blankets. These items can carry hair, dirt, and odors. Wash them separately from human laundry at 40°C (104°F) using fragrance-free detergent to protect your pet’s skin.

The Bottom Line

Your washing machine can do far more than keep clothes clean — it’s a secret hygiene powerhouse. Regularly washing these overlooked items reduces allergens, prevents mold, and keeps your household smelling fresh.

By using the right temperatures, gentle cycles, and simple tricks like pillowcases or vinegar, you extend the life of your belongings and create a healthier home. Sometimes, the secret to a fresher house isn’t about cleaning more — it’s about washing smarter.
