Stoneless is an effective scale remover. It removes scale, mineral and limestone deposits. Thus, the sulfates, iron, calcium, magnesium and other insoluble materials are detached from the surface. It transformes some of these into a water-soluble form, while disperses the insoluble parts and prevents their redeposition. Due to its corrosion inhibitor content after rinsing it is harmless to the painted and polished surfaces. Do not let to dry on the surface! After the impact time the remains of the product should be removed by thoroughly rinsing. In case of food-contact surfaces the efficiency of the rinse should be verified. The exposure time of surface cleaning is 5-20 minutes.
