How to Protect and Clean Limestone

Limestone is a beautiful natural stone that is perfect for any interior or exterior space. Here at Materials Marketing, we offer limestone in a variety of colors and finishes to compliment your unique style. We often get questions on how to keep this stone clean and looking as good as the day it’s installed. Cleaning limestone may seem like a challenge at first, but it is actually very easy to keep this stone looking great for years to come. Here are our tips for cleaning your limestone surfaces.

Preparing Your Limestone to be Cleaned

First, you want to remove all dirt, spills, and dust from the surface of your limestone. You don’t want to spread dirt particles as you mop or wipe. Limestone is soft, and they could scratch the surface. Vacuums can also scratch the surface if they have a spinning brush, so it is better to use a broom or dust mop to remove dirt. Once your surface is free of dirt and dust particles, you are ready to move on to wet cleaning.

Cleaning Your Limestone

Next, prepare a bucket of warm water mixed with either a mild soap or a cleaner designed specifically for stone. Limestone is very sensitive to acids, so avoid acid cleaners or cleaners derived from citrus. These can etch and damage the surface of the stone. Use a soft microfiber cloth or mop to clean the surface and remove the grime. Make sure not to miss any spots! Once you are done, rinse your surface with plain water to remove any soapy residue. Then, make sure to dry your stone surface with a soft towel. You don’t want to leave any standing water on your surface.

Removing Limestone Stains

Leaving standing spills like wine or juice will result in a stain on your limestone. It is best to wipe spills up immediately to prevent stains, but if you find yourself with a stain on your surface there are ways to remove it. First, you can try using a toothbrush and scrubbing in a circular motion with a mild soap mixture. If the stain doesn’t lift, you will have to try a poultice to draw the stain out. You can buy poultice products or make one yourself. To make your own, combine ¾ cup of flower and add hydrogen peroxide until you have a paste. Apply the mixture to the stain and allow to sit for one to two days, or until dry. Once dried, carefully remove with a soft edged scrapper.

Limestone Wear and Stain Prevention

The best way to fix wear and stains is to prevent them. Make sure to wipe spills as fast as possible to prevent any stains and to reseal your stone regularly. The seal will prevent liquids and dirt from penetrating the surface. Also, you will want to protect the surface from scratching. To do this, add rugs to entries and heavy traffic areas and use pads underneath furniture.
