Keeps limescale at bay - thanks to strong foaming action

Foaming action is released from the cistern with each flush, spreading cleaning agents and foam across the bowl surface to reduce visible scale and staining. The formulation is described as producing a hygienic cleaning foam on every flush.

Less frequent heavy scrubbing is required, so routine maintenance becomes quicker and simpler for busy households.

Fresh lemon scent between cleans - with citrus fragrance

Lemon-scented formulation is dispensed into the cistern water and carried into the bowl on each flush, providing a noticeable fragrance with regular use.

A fresher-smelling loo helps mask odours and gives greater confidence that the bathroom remains pleasant between cleans.

Long-lasting maintenance - with up to 800 flushes per block

Manufacturer information cites up to 800 flushes, roughly four weeks of action per block, indicating sustained release of cleaning and foaming action across multiple uses.

Fewer replacements are needed during normal household use, making routine upkeep less time-consuming.
