- Shower Sparkle rated below average for its effectiveness on mould and soap scum but trialists liked its smell and few reported skin irritations.
- McKenzie's Bi-Carb soda was the only genuinely natural product used but it wasn’t very effective at removing either mould or soap scum. It was however, pleasant smelling and non-irritating.

How we tested
120 Home Testers were each sent three mould and soap scum cleaners to use and evaluate. They were also given the appropriate face mask, goggles and gloves for the job, which is outlined on the product’s packaging. They were asked to use their usual cleaner to clean their bathroom before the trial and then use a test product once a week for three weeks.
Trialists were asked to rate each product for its effectiveness at removing mould and soap scum, its ease of use, smell and to give it an overall rating. Each product was tested an average of 45 times. The average score for each product was then converted to a percentage.
