How to Remove Rust Stains from Marble Bathroom Countertops (Without Damaging the Surface)

If you’ve just moved into a new home and noticed orange or brown discoloration on your marble bathroom countertop—don’t panic. Rust stains on marble can look alarming, especially when you’re dealing with a surface that is both beautiful and delicate. But with the right methods, you can restore the natural shine without resorting to harsh chemicals or replacements.

🧽 Why Rust Stains Appear on Marble
Rust stains typically develop on marble due to prolonged exposure to metal objects (like faucets or shaving cans) or water with a high iron content. The iron reacts with moisture and oxygen, leaving behind yellow or brown stains that can seep into the porous stone.

✅ Safe Methods to Remove Rust from Marble
1. Use a Poultice with Baking Soda and Hydrogen Peroxide
Ingredients: Baking soda, 3% hydrogen peroxide (food-grade), plastic wrap.

Instructions:

Mix the baking soda and hydrogen peroxide into a thick paste.

Apply the paste to the stain in a layer about ¼ inch thick.

Cover with plastic wrap and tape down the edges.

Let it sit for 24–48 hours.

Remove the wrap and scrape off the poultice gently with a plastic scraper.

Rinse with distilled water and dry completely.
