🍋 Acid Stains on Marble: Emergency Guide
Has a spill of lemon, orange juice or vinegar touched your marble floor? Acting within the first few minutes is crucial to avoid permanent damage to the natural stone.
Why Acids Damage Marble
Marble is a calcareous stone composed mainly of calcium carbonate. When it comes into contact with acidic substances (pH less than 7), a chemical corrosion reaction that:
- Eliminates shine leaving a matte or whitish mark.
- Create small pits or "engraved" on the surface.
- can penetrate if you don't act quickly.
Main domestic culprits: lemon juice, orange, grapefruit, vinegar, tomato, coffee and soft drinks.
First Aid: Act in the First 3 Minutes
Step 1: Absorb, DO NOT Rub
- Use an absorbent cloth or kitchen paper.
- Press gently to absorb the liquid.
- never rub: You would spread the acid and amplify the damage.
Step 2: Neutralize Immediately
- Prepare a solution with warm water and neutral soap (pH 7).
- Dampen a clean cloth and gently wipe over the area.
- Neutral soap helps neutralize residual acidity.
Step 3: Rinse and Dry
- Wipe another cloth with only clean water.
- Dry immediately with a soft, dry cloth.
- Don't let it air dry: water marks may remain.
What YOU SHOULD NOT DO
