To prevent limescal build-up and to improve steam emission, Polti suggests using Kalstop FP2003.
Kalstop FP2003 is an organic, biodegradable, non-toxic product that prevents limescale build-up for longer boiler life.
It also helps steam flow better and keeps applicances running efficiently, because it keeps steam passages clear, helping reduce energy consumption by permitting efficient operation.
- for models with traditional boiler, add one half or one phial of Kalstop whenever you fill the boiler, depending on how hard your water is.
- for cointinuous refill models, we suggest using one phial in five liters of water.
