Best Detergents for Coloured Clothes (2021 UK)

Everyone wants their clothes to stay looking new, but machine washing can often cause colours to fade. This is particularly true for dark colours such as black, navy and brown. Black jeans can almost become grey even after just a few washes.

There are several laundry detergents on the market that claim to prevent colour fade from even the darkest garments. Here are 5 of the best you can buy in the UK.

Detergents for protecting coloured clothes are available as washing capsules, powders or liquids, and come in a variety of pleasant fragrances too. All these products get good results and can prevent colour fading, giving buyers plenty to choose from.

Best Detergents for Coloured Clothes in the UK

1. Ariel 3 in 1 Colour Washing Capsules

Ariel 3 in 1 colour washing capsules may be small, but they offer powerful cleaning capabilities. Each capsule consists of three cleaning compartments in one pod that clean, protect and remove stains from clothes.

Unlike some washing capsules, these are intended specifically to protect coloured clothes from fading.

They also give your washing a really fresh smell, and are compact and easy to store, easy to use and perfect for students, house shares and holiday homes where sharing a large box or bottle of detergent isn’t always practical.

Because the detergent is sealed in the pod, it’s not possible to treat stains directly as with some detergents. Also, even though the capsules are easy to store, it’s essential that they are stored away from children.


  • Great for protecting coloured clothes
  • Compact and easy to store
  • Easy to use


  • Can’t treat stains directly as detergent is sealed in the pod
  • Can be hazardous to children and aquatic life, so must be stored safely


2. Surf Perfect Black Washing Liquid

Surf Perfect Black Washing Liquid is designed especially for dark clothes, and is perfect for items such as black jeans, to help them retain their vibrant colour and keep them looking good for longer. As this is a liquid detergent, it’s also excellent for pre-treating stains before a wash.

This detergent comes with a dosing ball, which you fill with the required amount and place in the drum of the washing machine. 35ml is recommended for standard sized loads (4-5kg) and 52g for larger or more soiled laundry, and for hard water areas.

Those who have tried this detergent are often impressed with this product’s lovely fragrance, and most are satisfied that it protects dark clothes in the wash too.

The combined power of the wash boosters and colour protect technology means that clothes can be cleaned effectively yet gently at lower temperatures, protecting the fibres in clothes which in turn keeps colours looking vibrant for longer.

This washing detergent also receives favourable reviews online for its excellent cleaning properties and its ability to keep colours from fading.

  • Available in large packs, great for families


  • Because this is a powder detergent, it’s not as easy to pre-treat clothes compared to a liquid detergent


4. Ariel Colour & Style Washing Liquid

Ariel Colour & Style Washing Liquid is designed to keep coloured clothing looking bright and vibrant wash after wash, while still being tough on stains.

One of its selling points is the pre-treat cap, which allows precise treatment of specific stains, and also allows detergent to be measured out precisely.

The cap features a spreading surface and flexible fins which allow you to spread and scrub the stain before washing.

The cap can also be filled with the detergent and placed into the washing machine drum before a wash. In addition to being kind to clothes, this product is also gentle to those with sensitive skin.

This washing liquid can be bought in a bottle providing around 24 washes, and although it’s not cheap the general opinion amongst those who’ve used this product is that it’s worth the price for the excellent stain removal capabilities and for protecting coloured clothes well.

The only real disadvantage of this product is that some users find the cap difficult to open.


  • Great for protecting coloured clothes
  • Gentle to skin
  • Excellent for pre-treating stains

5. Woolite Detergent Extra Dark Protection

Woolite Detergent Extra Dark Protection is intended to protect clothes with dark patterned fabrics and keep the colours look intense and brand new.

Our clothes tend to fade in the laundry due to repeated exposure to chemicals and mechanical wear, and this detergent promises to protect against this damage.

It doesn’t contain any harsh chemicals such as bleach, or any phosphates, which can cause fibres to fray and damage clothes – but it still has sufficient cleaning power.

This product is one of the best laundry detergents in the UK for dark clothes, but it can be hard to find in the shops and may need to be purchased online.


  • Great for protecting coloured clothes
  • Specially formulated for dark patterned fabrics and chemical and phosphate free


  • Can be difficult to get hold of in shops

How to Wash Coloured Clothes

Use a specialised detergent

Specialised detergents formulated to protect coloured and dark clothes really do work. These products protect the fibres in clothes so they stay looking good, and they can also help hold the dye in place during the wash cycle. Detergents designed to protect coloured clothes also contain fewer damaging chemicals such as bleach.

Do your clothes really need washing?

Washing darker coloured clothes more frequently will make them fade quicker, so it’s worth asking yourself if your clothes can last a bit longer without a wash. Of course, it’s always a good idea to wash underwear and sportswear after a single wash. Otherwise, try treating stains and marks with stain remover or a sponge.

Wash dark colours together

When clothes are washed, dyes can run from darker clothes. If there are no lighter clothes to soak up any dark dyes, the dye is reabsorbed into the dark clothes.

Turn clothes inside out

Turn garments inside out when washing as the surface exposed to the wash cycle receives the most wear, causing the dye to fade quicker.

Use cold water

Dark colours tend to fade more quickly when washed in warm temperatures, as the heat encourages the dye to loosen from the fibres in the fabric.

A liquid detergent may produce better results at lower temperatures on dark clothes, as powder sometimes doesn’t fully dissolve and can leave a dull residue on clothes.

Use a short washing cycle

Ideally, it’s a good idea to select a short wash cycle when washing dark clothes, to prevent the dye from running and fading.

Drying coloured and dark clothes

Dark and black clothes are best dried naturally and not in tumble dryers if possible. Try to hang the clothes to dry or dry flat, and if drying outside always avoid direct sunlight.

If you have no choice but to use the tumble dryer, try to remove the clothes whilst still slightly damp.
