Whether you're a regular cleaner or an infrequent one, the job is made much easier with an effective toilet cleaner.

Our expert testers

We buy toilet cleaners available from major supermarkets and use our laboratory for testing them. We also work out value for money of each product by unit value per 100mL.

We also include a home remedy in our testing. Our home test is made up of ¾ cup borax, 1 cup white vinegar, 10 drops of tea tree oil, juice of one lemon and 10 drops of dishwashing liquid.

How we choose what we test

With a range of products on the market, what makes us choose one toilet cleaner to test over another? As with most of our product testing, our aim is to test the most brands on the market and what you're most likely to see in stores.

We check in-store to see what's available and survey manufacturers to find out about their range of products. From this information we put together a final list that goes to our buyers. They then head out to the retailers and purchase each product, just as a normal consumer would. We do this so we can be sure they're the same as any consumer would find them and not 'tweaked' in any way.

How we test

Overall score

Lab experts put each toilet cleaner to the test by soiling white ceramic tiles with a NASA specification faecal test soil. Using a scrubbing apparatus attached, the tiles are scrubbed. The reflectance readings are measured before and after cleaning to determine the overall score which is a measure of dirt removal.

Test criteria explained

Dirt removal accounts for 100% of the overall score.
