Removes calcium deposits from pool covers and other surfaces (like PVC sheets, tiles, stainless fittings and bright surfaces). Calcium deposits in the pool can be removed during pool operation. Will not damage sheeting, tiles, m-joints, plastics or metal parts in the pool. Roldeck Ontkalker is not a conventional cleaner, but an advanced technology agent that converts calcium ions into solid particles that are trapped in the filter and removed by back washing. Helps reduce ongoing calcium deposits each time Roldeck Ontkalker is used.
Moisten the entire pool cover with Roldeck Ontkalker (1 litre per 10m2) using a spray bottle or a sponge. Leave Roldeck Ontkalker to work for 1 - 2 hours (ensuring the surface doesn't dry out) then hose down vigorously with a water hose or (carefully) with a high pressure jet. Dissolved calcium may also be removed using scrubbing sponge and water. Leave the filter running continuously.
After treatment with Roldeck Ontkalker the pH will need to be raised. We recommend cleaning the pool cover with Roldeck Ontkalker at least twice a year.
