Marble is prized and delicate in equal measure. A single acidic cleaner can etch it permanently. This guide explains how to clean marble safely, and why laser cleaning suits this soft, reactive stone.
Key takeaways
- Marble is soft and reacts with acids, so acidic cleaners etch and dull it.
- Abrasive cleaning scratches the polished surface.
- Laser cleaning removes soiling without acids or abrasion.
- It suits statues, monuments and architectural marble.
Why marble is so easily damaged
Marble is easily damaged because it is soft and made of calcium carbonate, which reacts with acids, so acidic cleaners dissolve and etch the surface, leaving dull, rough marks. Its chemistry is its weakness.
The polished surface is also easily scratched, so abrasive methods leave visible marks. Marble needs a method that is gentle chemically and physically.
The trouble with common cleaners
Common cleaners cause trouble on marble: acidic products etch it, and abrasive pads or powders scratch the polish, both leaving permanent damage. Even some general cleaners are too acidic.
This is the same reactivity issue we cover for limestone cleaning, since both are calcium-based stones.
How laser cleaning protects marble
Laser cleaning protects marble because it removes soiling with light, with no acids and no abrasion, so the soft, reactive surface is not etched or scratched. It avoids both marble weaknesses at once.
It is controllable enough for statues, monuments and fine architectural marble, and it is recognised within BS 8221-1:2012. See our heritage cleaning service.
