Will acid damage Giallo Siena marble?
Yes, and permanently.
Answer
How do you clean Giallo Siena marble?
Keeping the surface
With a soft cloth or a non-abrasive mop and a cleaner made for marble, neutral in pH. Blot spills rather than wiping them, because a wiped spill spreads the acid across more surface. Nothing acidic and nothing with a scouring particle in it goes on Giallo Siena marble.
The figures
| Do | Why | Source |
|---|---|---|
| Soft cloth, non-abrasive mop | No scouring particle can scratch a polished surface | Published maintenance practice |
| Neutral-pH cleaner made for marble | Anything acidic etches the polish | Published material note |
| Blot a spill, do not wipe it | A wiped spill spreads the acid over more area | Published maintenance practice |
| Felt pads under furniture feet | The mark that a wet ring leaves is permanent on a polished face | Published maintenance practice |
| Keep cutting boards and coasters on the counter | Stone does not scratch easily, but a mark cannot be polished out alone | Published maintenance practice |
Why this stone behaves this way
Giallo Siena marble is 95 to 98 per cent calcite, so the rule that decides everything else is that acid is what damages it. Everything that is not neutral is a risk, and the abrasive particles in an ordinary household cleaner are a second and separate risk.
What these figures are, and what they are not This is the routine, not a treatment for damage already done. An etch is not a stain and no cleaner will shift it.
