Multi-purpose and kitchen cleaners
Which multi-purpose cleaners really work?
Performance
We test multi-purpose cleaners in a controlled lab environment. We cover tiles in a greasy soil. The cleaner is applied to a damp sponge and we use a scrub tester to clean the tile. Cleanliness is assessed by measuring the reflectance of the tile. We repeat this test four times and the results are averaged to obtain our overall score.
How we choose products to test
When deciding which cleaners to test we head straight to the supermarket, like any consumer would (we also search online if there are any popular brands we can’t find). We conduct a survey of the available products and then contact manufacturers to confirm their products aren’t about to change formula. We then head back to the stores, buy the products and then send them off to the lab.
Why is this free?
We’re dedicated to getting NZ consumers a fairer deal. We provide as much information as we can for free but we rely primarily on membership and donations to fund our work. You can help by becoming a Consumer member or making a donation. We’ll use your contribution to investigate consumer issues and work for positive change.
We've tested 31 multi-purpose cleaners.
