If towels smell musty even after washing, it’s usually not your detergent. It’s buildup + moisture. The fix is simple: clean the washer, reset the fabric with an odor booster, dry completely, and keep your storage space dry so the smell doesn’t come right back.
Quick picks (what works fastest)
- Reset the machine: washer cleaner tablets.
- Reset the fabric: laundry deodorizer/booster.
- Stop re-contamination: a dehumidifier for damp rooms + activated charcoal for closets and cabinets.

The exact reset routine
Step 1: Clean the washer first
Run a cleaning cycle using washer cleaner tablets. If the machine smells, the towels will too.
Use: Washer cleaner tablets
Step 2: Wash towels with a deodorizer/booster
This is for towels, gym clothes, and anything that smells “fine wet, bad dry.” Follow the product directions and don’t overload the washer.
Use: Laundry deodorizer/booster
Step 3: Dry completely (this is where most people lose)
Musty smell comes back when towels are even slightly damp and then folded or tossed in a basket.
- Don’t leave towels sitting in the washer after the cycle ends.
- Don’t overload the dryer.
- If they still feel heavy, run extra dry time before folding.
Step 4: Fix the storage environment
If your closet or laundry area stays humid, odors return. Use a dehumidifier where needed and charcoal in tight storage areas.
- For damp rooms: Dehumidifier
- For closets/cabinets: Activated charcoal odor absorber
Tip: If you have “mystery musty” towels, the fastest proof test is simple: after drying, let one towel sit folded overnight. If it smells the next day, it’s either washer buildup, storage humidity, or both.
