Why Does My Laundry Smell Musty? Natural Solutions for Fresh, Clean Clothes

Quick Answer

Musty laundry usually comes from moisture left in the machine or on clothes, not from the detergent. Start by cleaning your washing machine and drying clothes promptly. For a quick refresh, use a natural fabric freshener like Mrs. Meyer's Lavender Fabric Freshener.

You pull a load out of the washer and instead of that clean, fresh scent, you're hit with a musty smell. It's frustrating, but it's also a common problem with a few clear causes. The good news: you don't need harsh chemicals to fix it. With some simple habits and plant-based products, you can get your laundry smelling fresh again.

In this guide, we'll walk through why musty smells happen, how to correct them, and how to prevent them from coming back. You'll also learn which Mrs. Meyer's products can help keep your fabrics and home smelling garden-fresh.

Why Does Laundry Smell Musty After Washing?

A musty odor after washing is usually a sign that moisture or bacteria are lingering. If clothes sit in the washer for hours, bacteria can multiply and create that sour smell. Another common cause is a dirty washing machine—residue from detergent and fabric softener can build up in the drum and seals, trapping odors that transfer to your clothes.

Sometimes the issue is your laundry routine itself. Overloading the washer means clothes don't get properly cleaned or rinsed, leaving behind soil and detergent that can cause odors. And if you use too much detergent, it can leave a film on fabrics that traps bacteria. Finally, drying clothes at too low a temperature or leaving them damp can lead to mildew.

• Always remove clothes from the washer promptly after the cycle ends.
• Check the door seal and detergent drawer for mold or residue regularly.
• Use the correct amount of detergent—more isn't always better.

How to Get Musty Smell Out of Clothes Naturally

If your clothes already smell musty, start by rewashing them with a cup of white vinegar in the rinse cycle (skip the fabric softener). Vinegar is a natural odor neutralizer and helps break down residue. If the smell persists, try washing with baking soda—half a cup added to the drum can help remove odors.

For items that can't be washed often, like jackets or curtains, a fabric freshener spray is a quick fix. Mrs. Meyer's Lavender Fabric Freshener is made with essential oils and odor-fighting technology, and it's free from bleach, dyes, and parabens. It's perfect for refreshing fabrics between washes and leaves a calming lavender scent.

• Sun-dry clothes outdoors when possible—UV rays help kill odor-causing bacteria.
• Ensure clothes are completely dry before storing them.

Preventing Musty Smells: Washing Machine Care

A clean washing machine is key to fresh laundry. Once a month, run an empty hot water cycle with two cups of white vinegar or a washing machine cleaner. This helps remove buildup and kills mold and mildew. After each use, leave the door open for a while to let the drum dry out completely.

For front-loaders, pay extra attention to the rubber gasket—wipe it dry after each load. Also, clean the detergent drawer regularly to prevent clogs and mold. These simple steps go a long way in preventing musty odors from developing in the first place.

• Use high-efficiency detergent if you have a HE washer to avoid excess suds.
• Don't leave wet clothes in the washer overnight—set a reminder if needed.

Diagnosing Your Musty Laundry Problem

• Symptom: Clothes smell musty right after washing or when you open the washer. If the smell is only occasionally, it might be from leaving clothes in the washer too long.
• Likely Cause: Moisture or bacteria in the washing machine, or clothes left damp for too long. If the smell is consistent, check for mold in the door seal or detergent buildup.
• Corrective Action: Clean your washing machine with vinegar, rewash clothes with vinegar or baking soda, and dry thoroughly. If the smell persists after two rewash attempts, the fabric may need a different treatment.
• Stop or Choose Another Option: If the musty smell remains after cleaning and rewashing, consider that the item may be beyond saving or need professional cleaning. At this point, you might also consider a fabric freshener as a temporary fix, but if the odor is deep-set, replacement may be necessary.
