Rust stains are among the biggest enemies of natural stones. Due to their rust composition, chemical composition and molecular structure, they can occur on any kind of natural stone. When you see rust-like colors on a light-colored marble, it is likely that there is a strong iron deposit in the stone, and this rust is waiting for the chemical process to begin to oxidize again. In kitchens or floors made of natural stone, the owners should be more careful about rust stains more than water spots. A natural stone with a high deposit of rust can be corroded in a short time. Here’s what you can do to prevent and remove rust stains on natural stone:
Preventing Rust Stains
The best way to prevent rust stains on natural stone is to protect your stone before rust stains occur, so you should not expose your stone surface to water. But this is impossible when it comes to bathrooms and kitchens, so the best preventative measure would be to use granite sealant frequently. Since the sealing material improves the seal of your stone, it will prevent corrosion from the inside. In this case, all you have to worry about is surface rust which is very easy to clean.
What You Should Never Use to Handle Rust Stains
All the suggestions for the use of acidic substances and general cleaning products for removing stains on natural stone are also valid for rust stains. It may make sense to use lemon juice or vinegar which are used on solid surfaces such as ceramics on your natural stone. However, such abrasive and acidic substances should not be used on your stone as they can damage the natural stone.
Removing Surface Rust
As long as your natural stone has a new sealing, the rust visible on the stone is probably only a superficial stain and can easily be removed with a soft brush or scouring pad. A strong seal created by a good sealing does not allow oxidized liquids to leak between the pores of the stone, so you only have to deal with superficial stains. To ensure the safety of your stone, it is a good idea to apply a coat of paste after removing rust and other surface stains.
Dealing with Stubborn Rust Stains
After the scrubbing process on your natural stone, all of the rust stains may not be removed. Even though the stains appear to be just below the surface and easily removed, if they still have not been removed after scrubbing, they will need to be cleaned by a professional. However, you can also try the method below before calling a professional. Spray the stained area with about 3 percent hydrogen peroxide, then rub the stone with a granite cleaning pad and then rinse it with water for 24 hours. If the stains still remain, it’s time to call natural stone experts to repair.
