How to use bicarbonate of soda to soften towels

Bicarbonate of soda can help restore towels that have become stiff because of built-up detergent, water minerals and fabric conditioner. It works as a laundry aid, helping to remove odours and residue, but it should not entirely replace the detergent needed to lift 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, regular use of fabric conditioner, mineral-rich water, an overloaded washing machine and high-temperature drying can all reduce softness and absorbency.

• Using more detergent than the recommended amount;
• Adding fabric conditioner to every wash;
• Putting too many towels in the same cycle;
• Allowing residue to remain because of insufficient rinsing;
• Tumble-drying items for too long;
• Storing towels before they are completely dry.

How does bicarbonate of soda help restore softness?

Bicarbonate of soda is a mildly alkaline compound that may balance the washing water, neutralise odours and reduce mineral deposits on the fibres. This can leave towels feeling lighter, particularly when stiffness has resulted from excessive amounts of laundry products.

The effect does not come from an ability to “rebuild” the fabric, but from gradually removing the substances compressing the fibres. Fabric conditioner can create a coating that lowers water absorbency, while using less product and managing excess detergent helps maintain towel performance.

How should bicarbonate of soda be used on towels?

For a medium-sized load, add two to three tablespoons of bicarbonate of soda directly to the empty drum, then place 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 appliance manual before adding household products.

Can bicarbonate of soda completely replace detergent?

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

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

How can towels stay soft for longer?

Avoid filling the washing machine too much, 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. It can be used when towels start to feel rough or develop a lingering odour. As with other household combinations used for clothing care, it is important to avoid random mixtures and follow the fabric care label and washing machine manual.
