Marble turning white
Why is my marble turning white
There are two possible answers to why your marble is turning white. One is a process called efflorescence and the other is called etching. Efflorescence is the leftover deposits of salt caused by evaporation and etching is caused by acidic substances. Both can turn your marble white.
How to take out staining
Efflorescence can be cleaned with a solution of muriatic acid, while etching requires professional polishing and restoration. To prevent etching, acidic substances such as lemon juice, wine, and vinegar should be cleaned immediately from the marble surface and use coasters or placemats under acidic drinks.
Efflorescence
- Mix a solution of 1 part muriatic acid to 10 parts water. Wear gloves and eye protection when using muriatic acid.
- Apply the solution to the stain and let it sit for 5-10 minutes.
- Scrub the white with a stiff-bristled brush or a white scrub pad. Gently scrub to avoid scratching the surface of your marble.
- Wipe the area clean with a damp cloth.
- Neutralise the acid by rinsing the area with water and dry the area thoroughly with a clean, dry cloth.
Important Note: muriatic acid should be used with care as it can damage the surface of the marble if left on for too long, or if the concentration is too strong. It’s best to test the solution on a small, inconspicuous area before using it on the whole surface.

How to take out staining
To remove the rust stains from your marble you can use a mild abrasive and water to create a paste. Rust stains are a bit more difficult because they are going to be deeper in the marble. Scrubbing the area gently to avoid damage to the marble is recommended.
