Is limescale corrosive?

The mere presence of limescale will not corrode the tubes or the boiler. However, proper maintenance is required to prevent problems occurring due to limescale. Limescale build-up can reduce the release of the steam, thereby reducing its flow to the point of complete obstruction. To prevent this problem occurring, all you have to do is maintain the efficiency of the boiler by regularly rinsing it (in the models with safety cap or with the No Calc System device) and using tap water mixed with 50% demineralised water or combined with the natural anti-limescale product Polti Kalstop.

Attempting to remove limescale build-up with DIY remedies (vinegar, lemon) or, worse, with the anti-limescale detergents that are found on the market may lead to extremely fast corrosion (perforations in the boiler, dirt spillage, etc.).

Absolutely do not use distilled water, dryer condensate water, perfumed water, rain water, battery water, water from air conditioning systems and the like. Do not use chemical substances or detergents.
