Best washing powders revealed by Which?

Cheap and big brand washing powders tested


Our latest test of washing powders has revealed two new Best Buy detergents that do an excellent job of busting stubborn everyday stains.

We’ve also found an economically priced supermarket own-brand washing powder that leaves clothes clean for a fraction of the cost of the big brands.

Our latest washing powder test put the cleaning power of washing powders from leading brands Daz, Persil, Ariel, Bold, Ecover and Surf under the microscope, as well as popular supermarket brands from Sainsbury’s, Aldi and Asda to see how they size up.

‘The bleach in washing powders may be harsher on coloured clothes but if you want your clothes the cleanest they can be, you’ll need to choose a powder.’

Washing powders also do a better job at getting those whites to shine, but there are cases where it pays to have a good liquid detergent to hand. Find out more about
