How Bicarbonate of Soda Can Restore Stiff Towels

Bicarbonate of soda can help restore towels that have become stiff because of built-up detergent, minerals in the water and fabric conditioner. It works as a laundry aid, helping to remove odours and residue, but it should not completely replace the detergent that removes sweat, body oils and dirt from the fabric.

Why do towels become rough after repeated washing?

Towels usually become stiff when residue builds up between the cotton fibres. Too much detergent, frequent use of fabric conditioner, mineral-rich water, an overloaded washing machine and drying at high temperatures can all lessen their softness and absorbency.

• Using more detergent than the recommended amount;
• Adding fabric conditioner to every wash;
• Putting too many towels in one cycle;
• Leaving residue behind because rinsing is insufficient;
• Drying the items for too long;
• Storing towels before they are fully dry.

How does bicarbonate of soda help restore softness?

Bicarbonate of soda is a mildly alkaline compound that can balance the wash water, neutralise odours and reduce mineral build-up on the fibres. This can leave towels feeling lighter, particularly when their stiffness results from excessive amounts of laundry products.

The effect does not come from an ability to “rebuild” the fabric. Instead, it gradually removes the substances that are making the fibres compacted. Fabric conditioner can create a coating that reduces water absorption, whereas using less product and keeping excess detergent under control helps towels retain their performance.

How should bicarbonate of soda be used on towels?

For a medium load, add two to three tablespoons of bicarbonate of soda directly to the empty drum, then spread the towels inside without overloading the machine. Put a reduced amount of detergent in its compartment, following the label instructions, and select the cycle stated on the care labels.

• Add the bicarbonate of soda straight into the drum;
• Do not pour the powder into the fabric-conditioner compartment;
• Use detergent suitable for your type of washing machine;
• Do not combine bicarbonate of soda and vinegar in the same cycle;
• Avoid using it on wool, silk or very delicate fabrics;
• Check the manual before adding household products.

Can bicarbonate of soda fully replace detergent?

Replacing detergent with three tablespoons of bicarbonate of soda for an ordinary wash is not advised. Bicarbonate of soda can help with odours, minerals and some residue, but it does not contain the same range of agents that remove body oils and dirt attached to the fibres.

A more balanced approach is to lower the detergent dose when there are signs of build-up and use bicarbonate of soda as an occasional aid. Washing-machine manufacturers advise placing it in the drum rather than in dispensers, as the powder may collect and cause blockages in certain models.

How can towels stay soft for longer?

Do not overfill the washing machine, use only the necessary amount of detergent and leave enough room for the items to move during rinsing. Shaking each towel before placing it on the washing line or in the tumble dryer helps separate the fibres, while correct drying prevents stiffness, damp smells and damage caused by excessive heat.

Bicarbonate of soda does not need to be included in every wash. Use it when towels start to feel rough or develop a persistent odour. As with other household combinations used for garment care, avoid random mixtures and follow both the fabric care label and the washing-machine manual.
