Limestone is a well-known type of stone composed primarily of calcium carbonate. It forms naturally when springs or other bodies of water precipitate, leaving behind calcium-like minerals that eventually solidify into limestone.
Limestone has been used mostly for construction. It is commonly used as aggregate in concrete or pulverized and combined with resins to produce engineered stone. Limestone's distinctive appearance and heat-resistant properties also make it an attractive choice for tiles, walls, and kitchen countertops.
How to Clean Limestone?
Limestone is a beautiful and durable natural stone that adds character to homes. However, like all-natural surfaces, it needs regular maintenance to preserve its appearance. Check out these steps below to keep your limestone looking its best!
Prepare the Limestone Surface
Start by clearing the limestone surface from dust, dirt, or any debris. You can use a soft brush or vacuum with a brush attachment to gently remove all the loose particles. By clearing the limestone surface before cleaning with solution, you will be able to prevent scratching from the surface. If you use limestone for outdoor areas, you can use a garden hose to rinse away surface grime.
Preparing the Cleaning Solution
The best cleaning solution for limestone is a mild, pH-neutral cleaner mixed with warm water. If you don’t have them in your home, you can use a mixture of a few drops of dish soap. But if you aim for deeper cleaning, specially formulated limestone cleaners are the best choice. They are available on the market, so you can easily find them whenever you need them.
Do keep in mind, that you need to avoid acidic, alkaline cleaners, or bleach-based solutions as they can damage the limestone by etching the surface.
Cleaning the Limestone Surface
Dip a soft cloth or mop into the prepared cleaning solution and gently wipe the limestone. Avoid using hard-bristled brushes or abrasive pads, as they can scratch the stone. After cleaning, rinse the surface thoroughly with clean water to remove any remaining residue and allow the limestone to air dry or wipe it down with a soft towel.
Removing Limestone Surface Stains
Do you find a stubborn stain that is still present even after general cleaning? Use a combination of baking soda and water to address them immediately. You can create a cleaning pasta using these two products, and apply it to the stained area. Let it sit for 24 hours, before gently wiping it away with a damp cloth. If the stain persists, repeat the process or use a commercial limestone poultice.
Reapply Sealant to Limestone Regularly
To make limestone look new again you should regularly apply a high-quality limestone sealant. Sealing prevents water and stains from penetrating the stone, keeping it protected and vibrant. Reapply sealant every 1-2 years or as recommended by the manufacturer to maintain the limestone's appearance and longevity.
Common Cleaning Problems in Limestone
Limestone is relatively easy to maintain with regular care. But just like any other natural stone, it can also be prone to certain issues. Below are some of the common cleaning problems in limestone, and how to address them!
- Stains: Limestone is porous and can easily absorb liquids, leading to stains. Prevent stains by sealing the surface regularly and wiping up spills immediately. For existing stains, you can treat them with a poultice or baking soda paste.
- Mold and Mildew: Moist environments can cause mold and mildew growth. Prevent this by ensuring proper ventilation and keeping the limestone dry.
- Etching: Acidic substances like vinegar, or wine can etch the limestone surface. You can prevent this by using coasters and avoiding acidic cleaners. If you notice there are light etches on your limestone, try to polish them with a soft cloth and a stone polisher.
- Hard Water Stains: Hard water can leave mineral deposits on limestone. Prevent this by regularly wiping the surface dry and using a water softener. Additionally, you can clean hard water stains with a mixture of water and mild soap.
- Chips: Limestone can chip if impacted by heavy objects. Thus to prevent chips, you should avoid dropping any heavy items on the surface.
