As a seasoned cleaning expert with years of hands-on experience tackling tough stains, I've tested these reliable methods to restore your garments without dry cleaning or discarding them.
Here are 7 effective, time-tested tips for banishing mildew from fabrics:
Baking soda is a go-to powerhouse for stain removal, backed by its natural deodorizing and lifting properties.
- Mix 1 tablespoon of baking soda with 10 cl (about 1/3 cup) of water.
- Dab the stains with a clean sponge or soft cloth soaked in the mixture.
- Launder the item normally.
This method shines on fresh stains for quick, effective results.
- Rub the stain directly with pure Marseille soap.
- Machine wash as usual.
For recent stains, it often removes them on the first try, drawing from traditional French cleaning wisdom.
For stubborn stains, combine white vinegar with baking soda and lemon juice—a trusted trio in professional home care:
- Mix 1 tablespoon of baking soda with 25 cl (about 1 cup) of white vinegar.
- Add the juice of 1 lemon.
- Spray the mixture using a clean sprayer or apply with a soft cloth.
- Let the fabric dry in direct sunlight if possible.
- Wash normally afterward.
Borax powder is a highly effective natural cleaner for mildew, widely recommended by cleaning authorities.

Best for sturdy white fabrics only—always test first.

A safer option for colors than bleach.
- Spray 3% hydrogen peroxide directly on the stain.
- Wash as usual.
Caution: Stick to the 3% dilution for fabric safety.
Among the most potent for mildew on non-delicate fabrics—handle with care as a professional would.
Wear gloves, as it's strong.
- Dilute a small amount of ammonia in water.

For larger areas, spray diluted ammonia, wipe excess with a sponge, then wash. Always follow your product's instructions precisely.
