That musty smell means bacteria and/or mildew have colonised your towels. Here's how to eliminate it.
Understanding the Problem
The smell comes from: - Bacteria producing waste compounds - Mildew (fungal) growth - Both thriving in damp conditions
Simply rewashing with detergent often doesn't work because the organisms are embedded in fibres.
Method 1: Hot Vinegar Wash (Mild Cases)
For towels that are slightly musty.
What You Need
- White vinegar
- Hot water capability
- Normal detergent
Steps
-
Wash with vinegar only - Hottest water safe for towels (60°C ideal) - Add 2 cups white vinegar directly to drum - NO detergent this cycle - Full wash cycle
-
Second wash with detergent - Normal detergent amount - Hot water again - Full cycle
-
Dry immediately and completely - Tumble dry if possible - High heat for cotton - Don't leave damp
Method 2: Baking Soda + Vinegar (Moderate Cases)
For persistent odour.
Steps
-
Baking soda wash - 1/2 cup baking soda in drum - Hot water, no detergent - Full cycle
-
Vinegar wash - 1 cup white vinegar - Hot water, no detergent - Full cycle
-
Detergent wash - Normal detergent - Hot water - Extra rinse
-
Dry completely
Note: Don't mix baking soda and vinegar in the same cycle - they neutralise each other.
Method 3: Laundry Stripping (Severe Cases)
For deeply embedded smell that won't shift.
What You Need
- Bathtub or large container
- 1/4 cup borax
- 1/4 cup washing soda
- 1/2 cup laundry detergent
- Very hot water
Steps
- Fill tub with hottest tap water
- Add borax, washing soda, and detergent
- Stir to dissolve
- Add towels, submerge fully
- Soak 4-6 hours (water will turn grey/brown)
- Drain, wring towels
- Wash normally (no extra detergent)
- Dry completely
See our complete stripping guide.
Method 4: Oxygen Bleach (Alternative)
Steps
- Dissolve oxygen bleach (OxiClean) in hot water
- Soak towels 1-2 hours
- Wash with detergent
- Dry completely
Safe for colours.
When to Give Up
Replace towels if: - Smell returns within 1-2 uses after treatment - Multiple stripping attempts fail - Visible mildew staining won't remove - Towels are old anyway
Prevention
- Dry towels completely between uses
- Wash before smell develops
- Don't leave wet towels bunched
- Ensure bathroom ventilation
