Hard soap scum score
Hard soap scum is calcium stearate combined with carbon black (which provides the dark colour so soil removal can be measured). Calcium stearate is the most common hard soap scum and is created by the reaction of soap ingredients with calcium ions in tap water. In hard water areas, deposits are more likely to be mostly hard soap scum. The solution is applied to tiles and baked on at 180°C for one hour to simulate a tough soap scum. It is then scrubbed with 20 strokes of the scrub tester before soil removal is measured.
