The Starline Roldeck Ontkalker removes all calcium deposits from your pool quickly and efficiently.
Roldeck Ontkalker not only easily removes all the limescale on the slats of your pool cover, but can also be used to clean the pool walls and bottom. This can be done while you are swimming. This way, you can combine the pleasant with the useful.
The limescale is crystallised by the product and trapped in the filter. The limescale crystals will eventually be removed from the pool by backwashing.
The Roldeck Ontkalker is no conventional cleaner but an advanced technological agent that converts limescale deposits and calcium ions into crystals.
The slatted cover should be cleaned at least twice a year.
