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.
