Don't Buy Washing Powder And Laundry Detergent
Don’t Buy laundry detergents leave visible stains on your clothes, fade colours quickly and turn your whites dull grey. Find out which disappointing detergents you should avoid.
Just want to know which detergents are the best? Head straight to our Best Buy washing powders and laundry detergents.
Our stringent lab tests separate the laundry detergents you should avoid from those we recommend as Best Buys. The Don't Buy laundry detergents revealed by our tests can quickly fade whites and colours, and leave visible stains on your clothes. By contrast, Best Buy detergents are strong on stains and will keep your clothes bright.
Price is no indicator of quality, as we've found great-value Best Buys that cost as little as 10p per wash.
Washing powders and laundry detergents to avoid
Which? has tested laundry detergent from big-name brands – such as Ariel, Bold, Daz, Fairy, Persil and Surf – as well as supermarket own-brand detergents to uncover the very best and worst. Our test results show you which products are tough on stains and which Don’t Buys fail to shift everyday dirt.
- Our lab experts put every laundry detergent through rigorous scientific tests, so you can quickly find the best washing powder, liquid, gel or washing capsule.
- We give every laundry detergent an overall Which? test score, so you can see at a glance which are the best and worst of each type of detergent.
- We test the most popular laundry detergents, from supermarket own-brands to the priciest big brands, so you can find the best for your budget.
