Clean granite slabs and remove stains

The cleaning of granite depends, of course, on the type of pollution. The usual and regular maintenance cleaning can be carried out with a special granite cleaner. There are both ready-made products and home remedies for stains and soiling of various origins.

Types of pollution

The soiling of granite slabs can be divided into three groups of causes. Frequent causes, especially indoors, are fatty substances, oils and wax. They are difficult to clean and not always leaving any residue. The spots are mostly drawn into the porous surface and penetrated relatively deep. Special absorbent agents can, at least partially, absorb the substances. For fresh stains, the home remedy damp salt can help prevent further penetration by absorbing the moisture.

The cleaning of organic contamination such as blood or aggressive leaves is promising with hydrogen peroxide.
