Strong foaming, acidic shampoo to reactivate ceramic seals. Hydrophilic dirt such as dust, limescale and salts are removed by washing with the Reactivation Shampoo. Such dirt impairs the easy-to-clean effect and the hydrophobic effect of the ceramic-sealed surfaces. The acidic setting of the shampoo ensures that the dirt is loosened and removed. This revives the dirt and water-repellent properties of the ceramic coating.
