However, like any other natural stone, limestone requires regular cleaning and maintenance to keep it looking its best.
In this guide, we will discuss the proper techniques for how to clean and seal limestone to ensure that it maintains its beauty and longevity for years to come. So, whether you’re a homeowner with limestone floors or a business owner with limestone countertops, this guide is for you.
Understanding Limestone Composition and Characteristics
Limestone is a sedimentary rock composed mainly of calcium carbonate, which is the same substance found in seashells and pearls. Its formation process involves layers of calcite (a mineral form of calcium carbonate) being deposited over time by water and marine organisms.
One of limestone’s unique characteristics is its porous nature, which makes it susceptible to staining and damage from acidic substances. Proper cleaning and sealing are crucial to maintaining its appearance and integrity. Now, let’s dive into the steps for cleaning and sealing limestone.
11 Best Ways on How to Clean and Seal Limestone
1. Sweep or Vacuum Regularly:
The first step in cleaning limestone is to remove any loose dirt and debris from the surface. Use a soft-bristled broom or a vacuum with a brush attachment to avoid scratching the stone.
This will prevent dirt and grime from being ground into the stone during cleaning. If using a vacuum, make sure to empty the bag or canister beforehand to prevent dust and debris from being released into the air.
2. Use Mild Cleaners:
When it comes to cleaning limestone, less is more. Avoid harsh cleaners and chemicals that can damage or etch the stone’s surface. Instead, opt for a mild cleaner specifically formulated for natural stones, a gentle solution of warm water, and a few drops of pH-neutral dish soap.
Using a soft cloth or mop, gently clean the surface in a circular motion. If using a commercial cleaner, make sure to follow the manufacturer’s instructions.
3. Tackle Tough Stains:
If you encounter tough stains or buildup on your limestone, it may require a bit more elbow grease. Apply a paste using baking soda and water to the stained area. Let it sit for a few minutes before scrubbing with a soft-bristled brush.
Rinse the area thoroughly with warm water and dry with a soft cloth. Make sure to test this method on a small, inconspicuous area first to ensure it does not damage the stone.
4. Avoid Acidic Cleaners:
As mentioned earlier, limestone is susceptible to damage from acidic substances such as vinegar or lemon juice. These acidic cleaners can etch the surface of the stone, causing permanent damage. It’s best to avoid using these types of cleaners on limestone.
While they may work well on other surfaces, they are not suitable for natural stone. If you accidentally spill acidic substances on your limestone, clean it up immediately and thoroughly with water.
5. Remove Stains Immediately:
In addition to avoiding acidic cleaners, it’s essential to immediately clean up any spills or stains on limestone. The longer a substance sits on the surface, the more likely it is to penetrate and cause damage or discoloration.
Use a paper towel or clean cloth to blot the spill, then follow up with a gentle cleaning solution. This will help prevent staining and keep your limestone looking its best.
6. Seal the Stone:
Sealing your limestone is a crucial step in maintaining its appearance and longevity. A high-quality sealer will protect the stone from stains and damage, making it easier to clean and maintain.
Before sealing, make sure the surface is clean and dry. Use a soft cloth or brush to apply the sealer according to the manufacturer’s instructions. Let it sit for the recommended time before buffing off any excess residue with a clean cloth.
7. Regularly Re-Apply Sealer:
Sealing your limestone is a process that takes time; depending on the type and quality of the sealer used, it will need to be reapplied every few years.
To determine when it’s time to reapply, perform a simple water test by dropping a few drops of water on the surface. If the water beads up and does not absorb into the stone, then the sealer is still effective. If it absorbs, then it’s time to reseal.
8. Use Coasters and Trivets:
Prevention is key when it comes to preserving the appearance of your limestone. Using coasters and trivets under glasses, plates, and hot dishes will prevent scratches and stains on the stone surface.
Using placemats on dining tables and countertops is also a good idea to protect against spills. Avoid placing acidic foods and drinks directly on the limestone surface if possible.
9. Be Gentle When Cleaning:
When cleaning your limestone, it’s essential to be gentle. Avoid using abrasive cleaners or scrubbing too hard, as this can cause damage or etching on the stone surface.
Instead, use a soft cloth or mop and avoid applying excessive pressure. It may take a bit more time and effort, but gentleness is key to preserving the beauty of your limestone.
10. Avoid High-Traffic Areas:
Limestone is not as durable as other natural stones like granite or quartz and can be easily scratched or damaged by heavy traffic. Avoid using it in areas with high foot traffic, such as entryways or hallways. If you have limestone in these areas, take extra precautions to protect it, such as using rugs or mats.
11. Hire a Professional:
If your limestone is heavily stained, damaged, or in need of restoration, it’s best to leave it to the professionals. Attempting DIY solutions on severe issues can often cause more harm than good and may end up costing you more in the long run.
Professional stone restoration companies have the experience, tools, and knowledge to properly clean and restore limestone to its original beauty without causing damage.
Following these 11 best ways to clean and seal, limestone will help you maintain its natural beauty for years to come.
Remember to be gentle, avoid harsh chemicals, seal regularly, and seek professional help when needed. By following these steps, you can ensure your limestone looks its best and continues adding elegance and charm to your home or space. So, be mindful and take proper care of your limestone to enjoy its beauty for years to come. Happy cleaning!
