The problem
What happens every day without the right product
Limescale everywhere
Taps, showers and tiles get coated in white deposits that kill shine and hygiene.
Long, tiring cleaning
Without an effective descaler you scrub for ages with poor results and damaged surfaces.
Less efficient systems
Scaled boilers and nozzles consume more energy and fail earlier.
The solution
Targeted acid action: dissolves scale, respects surfaces
The professional acid formula attacks limescale deposits and dissolves them chemically: apply, rinse, and the surface is like new — no abrasion.
- Dissolves layered limescale deposits
- Restores machine efficiency
- For acid-resistant surfaces
