Introduction – How to Clean Limestone

Cleaning limestone can be difficult if you don’t know what to use. Some things may clean it but might damage the stone in the process. Depending on how much cleaning is needed, different products should be used for this task. 

To clean Limestone, use either a good quality limestone cleaner, or clean it with vinegar and baking soda. If you choose to use a commercial cleaning agent, ensure that the label states that it is safe for natural stone surfaces. 

In this article, the Cleaning King Team will take you through the steps for cleaning Limestone. Additionally, we will go through the process of cleaning limestone paving, rocks, steps, and more. We’ll also look at a few of the best limestone cleaners on the market.

Cleaning limestone can be done with several methods. The best way to clean Limestone is to use a cleaner designed specifically for natural stone surfaces. These cleaners clean and protect the surface, leaving it clean and shiny without damaging or dulling the finish of your limestone floor.

To clean Limestone:

  • Use baking soda mixed with vinegar and warm water to remove stains from your limestone floors. 
  • If stains persist, use only cleaners that are specifically formulated to clean natural stone surfaces, such as Limestone Countertop Cleaner.

Be sure not to allow cleaners to sit on the surface too long, as this may cause damage over time. This can be especially true if there are areas of efflorescence present that will have an adverse reaction when exposed to citrus-based cleaners.

The best way around this issue is by using dry powder cleansers such as Bar Keepers Friend® instead of liquids so that no rinsing is required after application.

How to Clean Limestone Floors

There are several things you can do to maintain and prolong the life of your limestone floors.  For starters, clean up spills immediately. This will help you to spread it evenly and keep your Limestone clean and shiny for years.

Apply a sealer once every other year or as needed, especially if you notice spills on top of your limestone tiles. 

To clean limestone floors:

  • Remove all dirt, debris, and dust with a clean broom. 
  • Use a cleaner like Black Diamond Stoneworks Limestone Floor Cleaner on stained or filthy floors.
  • Fill up a bucket with warm water and cleaning solution and clean the floor using a clean mop or rag. Leave it for a few minutes so that you can loosen up the grime, then wipe out excess water to leave behind a clean surface again. 
  • Apply a coat or two of stone sealant to protect limestone floors from future staining and spills, as well as sunlight damage. Do this once every few years for the best results.

To maintain cleanliness on your limestone floor: 

  • Sweep your floors daily using a clean broom to remove dust particles that can scratch the surface over time if not removed. 
  • Use an unscented mild detergent solution with a clean mop or rag in warm water, then wipe it dry immediately.
  • Use an appropriate scrubbing brush (soft) and diluted commercial cleaning agent along with lukewarm water is poured onto the affected area, which will be wiped away by dry cloth/mop after some time.

It is also recommended to deep clean limestone floors regularly, especially if they are frequently used. This will help prevent the build-up of dirt and impurities, which can negatively impact how shiny your floor looks over time. 

There are several types of stone cleaning products available on the market for this purpose. Still, it’s best to opt for eco-friendly solutions as far as possible so that you’re not harming anybody or anything further down the line. 

How to Clean Limestone Hearths

Limestone hearths are a great addition to any fireplace, but if they are not clean, you might start noticing black streaks on the walls or ceiling above them as well as in front of it.

To clean limestone hearths, clean the hearth with a warm damp cloth first. This will help prevent the build-up of dirt and impurities, which can negatively impact how shiny your floor looks over time.

  • Generally, if Limestone is cleaned regularly, it should be pretty easy to clean using normal household items like vinegar mixed with baking soda paste. 
  • Apply this mixture onto the surface, slowly rubbing gently until all stains are completely removed from limestone flooring surfaces.
  • If any spots remain after applying home remedies, use an abrasive cleaner.

How to Remove Algae From Limestone

There are multiple ways to remove algae from Limestone, like vinegar, baking soda with water, or an abrasive cleaner.

Baking soda and water is a great way to clean Limestone because it’s natural, inexpensive, non-toxic, and leaves no residue. Combine baking soda with warm water in a spray bottle for a homemade mix that will clean your limestone tiles while keeping them looking new.

To remove algae from Limestone:

  • Using vinegar mixed one part water and two parts white distilled vinegar, and add baking soda to make a paste.
  • After the clean Limestone with this solution, clean off any residue that might remain on it using a clean cloth or mop. 

If there are stains left after cleaning limestone flooring surfaces, use an abrasive cleaner like CLR (Calcium Lime Rust).

Some of the reasons algae may build up on Limestone include:

  • Limestone is incredibly porous, allowing algae to penetrate it more easily. 
  • Low-traffic or clean limestone surfaces frequently exposed to moisture can become magnets for dust, dirt, and bugs like ants. This attracts the algae, which feeds on this source of sustenance.
  • Another reason you might need to clean algae from limestone floors could be because there was a spill containing sugar or oil residue – whether accidental or intentional – in an area with stones installed nearby. 

Algae feed off sugars and oils, so these kinds of spills serve as food sources for them after they have dried out at least partially. That’s why cleaning up immediately is crucial! You should try using hot water mixed with baking soda if any spills.

Cleaning Limestone with vinegar and baking soda paste is a simple, eco-friendly home remedy that works well on most surfaces. If this doesn’t work, you can use an abrasive cleaner as a last resort method for removing algae from limestone flooring.

How to Clean Limestone Rocks

In some areas outside your home, you may have limestone rocks that need to be regularly cleaned. These rocks may include limestone statues and rock walls. 

While clean limestone rocks look great, it can be difficult to clean them and keep them looking good. Below are some tips on how you may clean your limestone rocks:

  • Using a garden hose or pressure washer with the correct nozzle is the best equipment for removing dirt from limestone surfaces. 
  • Make sure that if you use a pressure washer to start at low pressures and gradually increase as needed, high water velocity will cause damage over time. 
  • Cleaning limestone by hand should only be done when using gentle cleaners such as nonionic surfactants in mild alkaline conditions (pH neutral), soaps, or acidic compounds such as vinegar/citric acid solutions to avoid etching of surface materials.

There are a variety of ways that you can clean these natural structures, including using the following: 

  • Hot water mixed with baking soda, vinegar, and baking soda paste
  • Scrubbing cleaner is the last resort method for removing algae from Limestone.

Cleaning your home’s Limestone is important because oil spills make it an ideal place for mosses, mildews, and molds to grow on, which could lead to health problems if not cleaned up immediately after they dry out at least partially. 

To clean Limestone on outdoor surfaces:

  • Use hot water and vinegar mixed with baking soda (just enough heat, so it becomes like a paste)
  • Leave the mixture for about an hour, then clean with a clean wet cloth or sponge. 
  • If that doesn’t work, scrubbing cleaner can be used as the last resort method.


To clean Limestone in an outdoor area, you may consider using a power washer to clean the surface of Limestone but do so very carefully as it can damage Limestone and remove any sealers.

Power washers should only be used when necessary as they can cause damage if not handled properly. Many sealants exist today, which will protect your clean limestone surfaces after regular cleanings have been completed.

How to Clean Limestone Paving

Limestone paving can be a clean and low-maintenance material for your driveway, patio, or sidewalks. Limestone is a sedimentary rock that generally forms near bodies of water throughout the world.

To clean limestone paving tiles in high traffic areas such as kitchen and bathroom floors:

  • Consider using mops instead of wet cleaning cloths or sponges, which may leave mineral deposits or residue on your stones after repeated use over time. 
  • Using traditional mopping products like ammonia-free cleaners leaves behind an unfavorable film on concrete surfaces; 
  • Additionally, limestone paving can be cleaned with the use of baking soda and water. This is an excellent option if you need to clean your stone without leaving any harsh chemical residues behind. 
    • Baking soda will help remove stains while also neutralizing odors on your limestone surface! 
    • Vinegar works well since its naturally occurring acidity helps break down grime from oils that have been left behind.

Limestone is a highly porous material that easily absorbs dirt and grime on its surface. Cleaning limestone can be difficult because it generally does not respond well to chemicals used in traditional cleaning products.

How to Clean Limestone Steps

Limestone steps can be cleaned with natural products like distilled vinegar and baking soda. This is a simple but effective combination, and it’s also safe for pets since they are not toxic to animals.

For best results, clean your limestone steps weekly until you no longer notice dark spots appearing after rainfall or high humidity conditions.

To clean limestone steps:

  • Clean with a mixture of distilled white vinegar and water. 
  • The addition of baking soda will help remove any stains, while the use of lemon essential oil will leave behind a fresh scent that is better for your family than harsh chemicals in traditional cleaners!

Limestone steps can be used to create truly unique areas in your home. These beautiful designs have been carefully crafted by skilled artisans using only natural materials such as Limestone or marble. 

However, this process also means these stones need special care to keep them looking great longer. To clean limestone steps, it is essential not just to clean but add additional protective coating when necessary. 

This includes sealing regular intervals from moisture damage caused by UV rays that break down stone over time, whether your limestone steps are indoor or outdoor, clean and seal regularly to maintain their beauty.

When it comes to caring for your limestone tiles, you have a few options. You can use an acid-based cleaner designed specifically for natural stone to clean the surface and remove stains. 

However, if you want a more long-term solution that will protect both the grout and tile from staining or etching, then think about using sealant instead of an acidic cleaner when cleaning your limestone floors. Sealants are made up of acrylics which make them stronger than acid cleaners at combating discoloration on marble surfaces over time due to their milder pH levels.
