Bathroom grime can be tough for a cleaner to remove.
We’re dedicated to getting NZ consumers a fairer deal. We provide as much information as we can for free but we rely primarily on membership and donations to fund our work. You can help by becoming a Consumer member or making a donation. We’ll use your contribution to investigate consumer issues and work for positive change.
Our cleaning score is a measure of how well the cleaner removes soft soap scum. We clean a tile that’s had soft soap scum baked on, and measure light reflectance before and after scrubbing to assess cleanliness.
