Concrete, like natural stone, has fine capillaries which can be penetrated by moisture and dirt. The CleanTop system is part of the production process and as a result is permanently bonded in the stone. It gives the stone complete protection. Due to the Clean Factor, moisture and dirt cannot infiltrate the stone, or do so only partially. Marks can be quickly and easily removed with water and gentle external cleaning agents. And the surfaces have to be cleaned less often.


Ciara paving slabs are easy to clean and keep clean thanks to CleanTop protection, despite their diagonal structure. Leaf residue and marks disappear in time by themselves. They can also be removed quickly with little effort (only water and a gentle external cleaning agent are necessary).
The CleanTop system is part of the production process; the protection penetrates the whole of the stone and becomes part of it. Unlike other impregnated substances and coatings, the advantage of CleanTop is that it is not susceptible to mechanical damage and the effects of weathering. Colours and surfaces have a durable protective finish; they weather considerably less than uncoated and conventionally coated concrete slabs.
CleanTop's higher resistance to dirt and the reduced time taken in cleaning have been scientifically proven - by a report from the Ruhr University of Bochum. The decision by McDonalds to use our CleanTop products in Germany and Austria, the USA, Sweden and Canada for particularly heavy-cleaning areas also underlines our technology's advantages.
The CleanTop system was developed by Metten Stein+Design more than 10 years ago and has yielded excellent tried and tested results ever since! CleanTop is used not only in Germany and other European countries, but also in the USA and Canada!
