How we test cleaning

An overall rating showing how well the detergent removes a range of stains including tea, dried egg yolk, baked-on milk and pasta starch from cups, glasses, plates and baking sheets.

How we test preventing filming and cloudiness

How well the detergent prevents streaks and residue from building up on plates, glasses and crockery over multiple washes. The best detergents will keep items clear and streak-free wash after wash, but the worst will allow a white film or discolouration to form.

How we test preventing water marks

How well the detergent prevents watermarks and droplets on dishes.

How we test anti-dullness

How well the detergent prevents knives and pans from dullness, loss of colour or discoloration.

How we test environmental impact

Whether these detergents contain chemicals that have any negative environmental effects. This includes if they are biodegradable, harmful to aquatic life or persistent which means the chemicals could linger and accumulate in waterways. In addition we examine the packaging material to see whether it's recyclable or made from recycled materials, and we also consider if refills are available.
