Marble is one of the most beautiful materials you can use for countertops, backsplashes and other home surfaces. However, marble can encounter stains that will diminish the natural stone’s appearance. While this may seem concerning, there is no need to panic. Many marble stains, including those from rust, can be removed. This guide will help you figure out how to remove rust stains from your marble. 


How to Remove Rust Stains from Marble 

To remove any marble stains, you will first need to determine what type of stain you are dealing with (organic stains, water stains, hard water stains, etc.). Depending on the specific stain, there are different ways to go about dealing with it. 

To remove stains caused by rust, one method you can try is applying a poultice. If you do not succeed with this, you can also try using a rust remover product or consulting a marble restoration professional. 

Steps for Removing Rust from Marble 

A poultice is a homemade stain remover that is often used to treat most types of stains. It is a paste that is typically the consistency of peanut butter that is applied to the stained area. It is then covered in plastic wrap and left to sit for 24 to 48 hours before removing. In most cases, the poultice will draw the stain out of your marble countertops or other surfaces. 

To start, you will need to make the poultice by mixing a combination of ingredients. Some common poultice ingredients include baking soda, water, and in some cases, small amounts of hydrogen peroxide. Depending on the specific stain you have and the severity of the stain, the ingredients you need to use can change. Note that you should never use any harsh ingredients such as bleach or lemon juice, as these will further damage your marble. 

Once you have achieved the proper consistency, apply the poultice to the stained area. Then, cover it with plastic wrap. Lastly, let it sit for 24 to 48 hours before removing the plastic wrap and scraping off the dried poultice using a plastic spatula. 

After this time, your stain should be all gone. However, as mentioned above, if it is not, you may want to use a rust remover or call a professional. Make sure to clean your marble using a marble cleaner at the end of the process.
