Washing-up liquid Full washing-up liquid test results

We've tested washing-up liquid since 1959 and have developed a series of expert tests that match how you use washing up liquid in your home. We only award Best Buy washing-up liquid status to the liquids that are best at removing tough fatty foods.

The table below shows the score for each washing-up liquid we've tested, and how we rate each one for fat removing ability and foam duration. Best Buys are in red, with Don't Buys in grey.

Members can log-in to see the full test results, or if you're not a member you can try Which? for £1 and get instant access to this and all our other reviews.

Using the table

Price: What we paid for our samples. Prices correct at July 2013.

Fat removal: How well liquids removed grease and kept it suspended in water, rather than letting it escape back on to dishes.

Foam duration: How long the foam lasts for and how good the liquid is at cleaning less intensive everyday soils.

Score: The Which? test score is made up of: fat removing power 80% and foam duration 20%.
