To prevent limescale
from forming in the first place, Polti has
created KALSTOP FP2003, the natural
anti-limescale agent for steamers and steam generator irons.
KALSTOP FP2003 derives from a natural
product thus is biodegradable and nontoxic.
KALSTOP FP2003 is made of tannate, reducing oxygen in the water, protecting
against scale and corrosion, and protecting
the metallic walls.
Instructions: break open the phial and
pour the content into the boiler of Vaporetto
and Vaporella, previously filled
with water. Stronger solutions can be used (e.g. 1 phial per litre of water) if the water is particularly hard. For the models
with self-filling feature, we suggest to dilute the phial in 5 litres of water before
pouring it in the tank.
