We recommend toilet cleaners that achieve at least a 70% overall rating.

We test manual liquid toilet cleaners by using a scrub tester against synthetic faeces (based on a NASA formulation). We test three times and measure the soil removal by scanning the tile on a picture scanner, and then use colour assessment software to measure the area of tile cleaned. Results are scaled using a benchmark of 45% performance for tap water, and are rounded to the nearest 5% to account for statistical significance.

This refers to the consistency of the cleaner. A liquid will be easier to pour, but a gel will do a better job of clinging to the bowl where it's needed. Dry crystals are easiest to clean up in a spill, but need the toilet to be wet in order for them to stick, dissolve and work.
