Each stone reacts differently. Marble and limestone do not tolerate acids (they stain and corrode); granite is more resistant. We choose the product and pressure for each type, clean, without ruining the stone.
Why it is not worth putting off
Porous stone grabs moss and pollution, and the wrong product leaves permanent stains. Treating it well preserves the look and the value of the stone.
How we do it
- We identify the type of stone → the right product
- Neutral pH on marble and limestone (never acid)
- Pressure tuned to the hardness of the stone
- Always a test on a discreet spot before proceeding
Mistakes we see (and avoid)
- Acid on marble/limestone, stains and corrodes (irreversible)
- High pressure on soft stone, pits the surface
- A generic product with no prior test
