Cleaning, grinding and polishing marble and granite
- this is how your natural stone will shine again in Hamburg or Germany!

Marble and granite lose their shine over time if they are not cleaned properly or are subjected to heavy wear and tear. Marble in particular, as a calcareous stone, is sensitive to acidic and alkaline cleaning agents.
Granite, on the other hand, is harder and more resistant, but still needs to be cared for and polished regularly to maintain its beauty. Here you can find out everything about cleaning, grinding and polishing marble and granite and how you can care for your natural stone in the long term.
The correct cleaning of marble and granite
A common reason for marble losing its shine is the use of unsuitable cleaning products. Acidic products can damage the surface and cause dull spots. Marble is particularly sensitive to such products because it contains lime , which is attacked by acid.
To maintain the shine of granite and marble, we recommend special natural stone cleaners that protect the surfaces while cleaning them effectively. Regular care prevents stubborn stains and discoloration.
