Marble countertops are a beautiful addition to any kitchen or bathroom, but they require proper care and maintenance to keep them looking flawless. One of the most common issues with marble surfaces is the appearance of rust stains.

In this article, we will discuss how to clean rust off marble with DIY methods you can try at home, and preventive measures to keep your marble surfaces looking pristine.

Understanding Marble and Rust Stains

Before we dive into how to get rust off a marble counter, it’s essential to understand the nature of marble and rust stains. Marble is a natural stone that is porous, meaning it can absorb liquids and develop stains over time.

Rust stains are caused by iron-containing objects or minerals in the water coming into contact with the marble surface. These stains can be particularly stubborn and challenging to remove, so it’s crucial to act quickly and use the appropriate cleaning methods.

How to Clean Rust Off Marble

If you’ve noticed a rust stain on your marble countertop, there are a few initial cleaning methods you can try before resorting to more aggressive techniques.

Using a Magic Eraser

A magic eraser is a foam sponge that works through light abrasion, making it suitable for removing surface stains on marble. Gently rub the magic eraser over the rust stain, applying minimal pressure to avoid damaging the marble surface.

If the rust stain is light and has not penetrated the marble, this method may be sufficient to remove it entirely. After using a magic eraser, it’s a good idea to clean the area with a marble cleaner and reseal the surface to prevent future stains.

Applying a Baking Soda Poultice

For rust stains that have not yet penetrated deeply into the marble surface, a baking soda poultice may be an effective solution. To create the poultice, mix equal parts baking soda and water until you achieve a paste-like consistency.

Apply the mixture directly to the rust stain and cover it with plastic wrap, ensuring the edges are sealed. Allow the poultice to sit for 24 hours before carefully removing the plastic wrap and rinsing the area with water. If the stain persists, repeat the process as necessary.

Advanced Rust Removal Techniques

If the initial cleaning methods are not effective in removing the rust stain from your marble counter, you may need to resort to more advanced techniques. These methods should be approached with caution, as they can potentially damage the marble surface if not used correctly.

Using Hydrogen Peroxide

Hydrogen peroxide can be an effective solution for removing rust stains from light-coloured marble surfaces. However, it’s crucial to test this method in an inconspicuous area first, as hydrogen peroxide can potentially lighten dark-coloured marble.

To use hydrogen peroxide, cut a piece of gauze to the size of the stain and saturate it with the solution. Place the gauze over the stain, seal it with plastic wrap, and tape the edges.

Place a weighted object on top of the gauze to apply pressure and leave it for at least 24 hours. If the stain remains, repeat the process as needed.

Liquid Soap and Flour

Another method for removing rust stains from marble involves creating a paste using unbleached flour, mild liquid soap, and water.

Mix the ingredients until you achieve a thick consistency and apply it to the stain, overlapping the edges. Cover the paste with plastic wrap and let it sit for 24 hours.

Once the time has elapsed, remove the plastic wrap, wash the area with soapy water, and rinse thoroughly. This method may need to be repeated for stubborn rust stains.

Corn Starch

Corn starch (also known as corn flour) can be an effective solution for removing rust stains that have set into the marble surface. To use corn starch, first, spray the stained area with distilled water.

Then, cover the damp rust mark with a layer of corn starch and let it sit for at least 24 hours. Repeat the process as necessary until the rust mark is removed.

For grease stains, apply corn starch immediately to the affected area, and after 15 minutes, clean the spot with mild soap and water.

Rubbing Alcohol

For light stains or when the marble surface has not been sealed recently, a rubbing alcohol spray can help restore the marble’s shine and remove light rust stains.

In a clean spray bottle, mix a few drops of dish soap, 1/8 cup of rubbing alcohol, and water. Shake the bottle well and spray it on the stained area. The mixture should help remove light rust stains and add lustre to your marble counter.

Professional Marble Restoration

In some cases, rust stains may be too stubborn for DIY cleaning methods, and professional marble restoration may be necessary. This process typically involves grinding down the affected area of the marble surface and repolishing it to restore its original appearance. While this can be an expensive option, it’s often the most effective solution for removing deep-set rust stains from marble countertops.

Preventing Rust Stains on Marble

Prevention is always the best approach to maintain the beauty of your marble surfaces. Here are some tips to help prevent rust stains on marble countertops:

Sealing Marble Surfaces

One of the most critical steps in preventing rust stains on marble is ensuring that the surface is properly sealed. Marble sealers create a protective barrier on the surface, preventing liquids and stains from penetrating the stone. At Clean Seal, we use Nano Shield HD, an advanced sealant for marble that lasts up to 10 years. It is designed to give your marble surfaces a superior shine and resist staining from wine, lemon juice and heat damage.

Proper Cleaning and Maintenance

Regular cleaning and maintenance are essential for preventing stains on marble surfaces. Always use a marble-specific cleaner when cleaning your countertops, and avoid using harsh chemicals or abrasive materials that can damage the marble. Immediately wipe up any spills, especially those containing iron or acidic substances, to minimise the risk of developing rust stains.
