High-powered descaler powder for WCs is the descaling solution for difficult cases. Its concentrated effervescent powder is particularly effective for descaling toilet bowl walls and bottoms, releasing sulphuric acid on contact with water to eliminate limescale, even underwater.
Starwax High-Powered Descaler Powder for Toilets is compatible with septic tanks for an average of 2 uses per week. Beyond that, we recommend that you protect and maintain your tank with Starwax Long-Lasting Tank Maintenance.
If you have a macerating toilet: this product is not recommended as it can oxidise the metals in the mechanism. We recommend that you use the macerating toilet descaler.
