How to Wash Towels with White Vinegar and Avoid a Damp Smell

White vinegar has become a popular at-home option for anyone wanting to wash towels without that lingering damp smell trapped in the fibres. The idea is to swap conventional fabric conditioner for a small amount of the liquid and, if you prefer a scented finish, add a few drops of essential oil. Results also rely on proper rinsing, the right amount of detergent, and drying everything thoroughly.

Why use white vinegar instead of fabric conditioner?

White vinegar contains acetic acid and can help tackle build-up and odours in fabrics. When towels hold on to detergent residue or stay damp for too long, cutting down on that residue can leave the fibres less coated and improve how they feel. It will not turn into a traditional fabric conditioner, but it may support the wash process and help control that “stored away” smell.

Fabric conditioner works differently: its ingredients sit on the fibres to reduce friction and create a softer feel. With towels, however, that coating can reduce how well they absorb water when the product is used often or in large amounts-exactly the quality that matters most for this type of textile.

How can you stop towels from smelling damp?

An unpleasant smell is not only about what you pour into the machine. Towels are thick, hold a lot of water, and can stay wet for hours between showers. To reduce odour retention, a few steps during washing and drying make a real difference:

• don’t overload the washing machine drum;
• use only the amount of detergent you actually need;
• follow the temperature shown on the care label;
• take items out of the machine as soon as the cycle finishes;
• only put them away once they are completely dry.

Packing the washer too full makes it harder for water to move through the fibres, which can harm both washing and rinsing. Using too much detergent does not mean better cleaning either: some of it can remain in the fabric, especially in thick, highly absorbent items.

What are the essential oil drops for?

Essential oil is used purely for fragrance. A few drops can add a pleasant scent, but they do not remove dirt, kill micro-organisms, or replace detergent. There is also no need to increase the dose to make the smell stronger, because concentrated oils can linger in the fabric.

For that reason, it is not a good idea to pour it directly onto a dry towel. If you want the aroma, use the smallest amount possible and check the guidance both on the towel care labels and from your washing machine manufacturer. Fragrance is an extra; avoiding bad odours depends far more on washing properly and drying without any leftover moisture.

What should you consider before putting vinegar in the washing machine?

This tip is not automatically suitable for every washing machine. Manufacturers often warn that repeated contact with acidic substances can, over time, affect hoses, seals, and rubber components. Before adding white vinegar to the fabric conditioner drawer or the drum, it’s important to check your specific appliance manual.

• check whether the manufacturer allows vinegar to be used in the machine;
• don’t pour large quantities directly onto the items;
• follow the towels’ wash-care labels;
• avoid combining different cleaning products in the same cycle;
• never mix vinegar with bleach or any other chlorine-based product.

That last point matters in particular. Vinegar is acidic, and combining acids with the hypochlorite found in household bleach can release chlorine gas, which may irritate the eyes and airways and cause injury with heavier exposure. The two products must not be used together.

Softness also depends on how you wash and dry

Switching away from fabric conditioner on its own will not fix a towel that has gone stiff. Too much detergent, an overfilled drum, and residue trapped between the fibres can make the fabric feel heavy, while repeated use of fabric conditioner can build a layer that reduces water absorption. A suitable cycle, with enough room for movement and a full rinse, does a better job of protecting the towel’s absorbent structure.

Thorough drying is the final step. Folding and storing a towel that is still even slightly damp creates the conditions for that musty smell to return, even after washing. So, when your machine manual allows it, using vinegar, limiting fabric conditioner, keeping detergent amounts under control, and letting each item dry completely are the most relevant measures for keeping fibres absorbent, soft, and free from that familiar damp odour.
