How to Wash Clothes with Table Salt: Benefits, Steps and Care

Washing clothes with table salt has become an increasingly common household practice among people looking for simple ways to care for garments more effectively. By adding a small amount of sodium chloride to the wash, it may enhance the action of detergent and help protect fabrics, particularly dark and brightly coloured items, as a supplementary option alongside conventional laundry products.

Why can washing clothes with table salt be beneficial?

Salt interacts with textile fibres and dyes, helping to limit fading and reduce colour transfer into the water, especially with dark or strongly coloured garments. As a result, T-shirts, trousers and towels may retain their intensity for longer during their first few washes.

In certain cases, using salt in moderation can also leave garments feeling more pleasant, acting as an addition to fabric conditioner in straightforward washes. It may also help remove light sweat residues and surface dirt, contributing to a more even-looking fabric.

How to wash clothes with table salt at home, step by step

To try using salt in the laundry, follow a few straightforward steps and avoid using too much. Ordinary refined table salt should be used in a small quantity, always alongside your usual detergent, without substantially changing your machine-washing or hand-washing routine.

1. Sort the garments: Separate clothing by colour and fabric type, as recommended for any wash.
2. Measure the salt: For general washes, around 1 tablespoon of salt is commonly used for a medium load. Add it directly to the detergent drawer or into the drum.
3. Choose the wash cycle: Select the programme suited to the fabric, prioritising dark and coloured garments, which are the main candidates for this method.
4. Rinse as normal: Keep the machine’s usual rinse cycle so that both the salt and detergent are fully removed.
5. Dry the clothes: Dry items in the shade where possible, particularly fabrics that fade easily.

For hand washing, salt can first be dissolved in cold water with the detergent. This can provide gentler care for delicate pieces, including underwear, fine cotton T-shirts and lightweight fabrics in general.

How to use salt for stains and colour preservation

Beyond routine washing, many people use salt in a more targeted way to support colour retention and deal with minor stains. In these situations, it is essential to consider the balance between water, salt and the length of time the fabric is left in contact with the mixture, avoiding residue while achieving a good result.

When used in pre-treatments or specific preparations, salt can be included in different everyday ways:

• Setting the colour of newly purchased garments: Soaking new coloured items in cold water with a few spoonfuls of salt for several hours before their first wash may reduce pigment loss.
• Supporting dark clothing: Adding a little salt during the first washes of black or navy garments can help reduce the faded, whitish appearance that develops over time.
• Treating isolated stains: Making a paste with salt and a small amount of water, then applying it to fresh sweat marks or water-based food splashes before washing, may improve stain removal.

When is washing clothes with table salt not recommended?

Salt is not suitable for every situation, particularly with very delicate fabrics, dry-clean-only items or garments with sensitive embellishments, such as metallic embroidery and beading. In these cases, following the care-label instructions remains the safest way to preserve the item.

It is also important not to use too much salt in frequent washes, as larger quantities do not increase the benefits and may encourage residue to build up in the machine, requiring more regular cleaning. Using salt moderately and alternating it with conventional washes is generally a more balanced approach to keeping clothes protected, their colours stable and their feel pleasant for longer.
