Washing Clothes with Table Salt: How to Use It at Home

Washing clothes with table salt is a household habit that has been gaining popularity among people looking for straightforward ways to care for garments. By adding a small amount of sodium chloride to the wash, many aim to boost the detergent’s performance and help protect fabrics-particularly dark and brightly coloured items-as a complement to standard laundry products.

Why can washing clothes with salt be advantageous?

Salt can interact with textile fibres and dyes, helping to limit fading and reduce colour bleeding into the wash water, especially with dark or highly coloured clothing. As a result, T-shirts, trousers, or towels may keep their intensity for longer during the first few washes.

In some cases, using salt in moderation can also leave clothes feeling nicer to the touch, working as a simple addition alongside fabric conditioners in everyday washes. It may also help lift light traces of sweat and surface grime, supporting a more even-looking finish to the fabric.

How to wash clothes with salt step by step at home?

To try using salt in your laundry routine, you only need a few straightforward steps-while avoiding overdoing it. The best approach is to use a small amount of ordinary fine table salt, always alongside your usual detergent or soap, without making major changes to your machine settings or hand-washing routine.

1. Separate the items: sort clothes by colour and fabric type, as recommended for any wash.
2. Measure the salt: for general loads, it is common to use about 1 tablespoon of salt for a medium load, added directly to the detergent drawer or straight into the drum.
3. Choose the wash cycle: select a programme suitable for the fabric, prioritising dark and coloured garments, which are the main candidates for this method.
4. Rinse: keep the machine’s normal rinse so the salt and detergent are fully washed out.
5. Dry: dry in the shade where possible, especially for fabrics that fade easily.

For hand-washing, the salt can be dissolved beforehand in cold water along with the soap. This can support gentler care for sensitive items such as underwear, fine cotton T-shirts, and lightweight fabrics in general.

How to use salt for stains and to preserve colours?

Beyond routine washing, many people use salt in a more targeted way to support colour retention and deal with small stains. In these situations, it is important to pay attention to the balance between water, salt, and contact time with the fabric, to avoid residue and achieve a good outcome.

When used in pre-treatments or specific preparations, salt can be introduced into day-to-day laundry in different ways:

• Set colours in newly bought items: soaking new coloured garments in cold water with a few tablespoons of salt for a few hours before the first wash may reduce pigment loss.
• Strengthen dark clothing: adding a little salt during the first washes of black or navy items can help reduce the dull, whitish look that develops over time.
• Treat small, localised stains: making a paste with salt and a little water and applying it to fresh sweat marks or water-based food splashes before washing may improve removal.

When is it not recommended to wash clothes with salt?

Salt is not suitable for every situation, particularly for very delicate fabrics, items labelled for dry cleaning, or clothes with sensitive embellishments such as metallic embroidery and beading. In these cases, following the care label remains the safest way to preserve the garment.

It is also important not to use too much salt in frequent washes, because larger amounts do not increase the benefits and may encourage residue build-up in the washing machine, meaning it will need cleaning more often. Using salt sparingly, alternating with conventional washes, is usually a more balanced approach for keeping clothes in good condition-helping colours stay stable and fabrics feel pleasant for longer.
