Black mold stains in the bathroom, especially black stains in the shower, are among the most frustrating cleaning problems at home. These dark marks appear on walls, grout lines and shower silicone. Even after careful cleaning, they often return in the same spots. Many people assume it is just surface dirt or a weak cleaner. However, in most cases the real cause is deeper. It is usually linked to organic buildup and persistent moisture in the bathroom.

In a villa located in the Tuscan countryside, a restoration was carried out on an outdoor terracotta floor, which had deteriorated due to mould, lichens, moss, and black stains caused by moisture. The main goal was to effectively remove mould and lichens and protect the material over time.

During the cleaning phase, the team used ALGANET®—a professional stain remover specifically formulated to eliminate biological colonies from terracotta and stone surfaces. The treatment successfully removed even the most stubborn encrustations without damaging the material.

Afterwards, they applied TIM®—a transparent and breathable protective product designed to prevent the future formation of mould, stains, and new lichens. This product has the advantage of preserving the aesthetic appearance of terracotta while maintaining its breathability.
The final result is a fully restored terracotta surface: clean, protected, easy to maintain, and resistant to atmospheric agents. This intervention stands as a concrete example of how to remove mould and lichens in a long-lasting and professional way, thanks to Marbec products.

Dark stains on kitchen countertops, especially mold on kitchen countertops and dark stains on stone countertops, are more common than many people think. Even when surfaces look clean, blackened areas can still develop.
These stains usually appear near the sink, along sealed edges, inside joints and grout lines. In these areas, moisture and organic residue tend to accumulate. At first, they may seem minor. However, over time, they become more visible and increasingly persistent.
