Bluestone is a type of flagstone that is prized for its unique blend of blues and grays, making it a popular choice for outdoor spaces, walkways, and patios. However, like any natural stone, bluestone requires regular cleaning to maintain its appearance and extend its lifespan. But what can you use to clean bluestone? In this article, we’ll explore the different methods and products available to help you keep your bluestone surfaces looking their best.
Understanding Bluestone and its Cleaning Needs
Before we dive into the cleaning methods, it’s essential to understand the properties of bluestone and its unique cleaning needs. Bluestone is a metamorphic rock that is composed of quartz, feldspar, and mica minerals. These minerals give bluestone its distinct color and texture, but they also make it prone to staining and damage from harsh chemicals.
Bluestone is a porous stone, which means it can absorb liquids and substances easily. This porosity makes it susceptible to staining from dirt, oil, and other substances. Additionally, bluestone is relatively soft compared to other natural stones, which means it can be scratched or etched by acidic substances or abrasive cleaners.

Now that we understand the properties of bluestone, let’s explore the different cleaning methods available:
Mild Soap and Water
One of the most effective and gentle ways to clean bluestone is with a mild soap and warm water. This method is suitable for removing dirt, dust, and minor stains from the surface of the stone. Here’s how to do it:
- Mix 1 tablespoon of mild soap, such as diluted dish soap, with 1 gallon of warm water.
- Dip a soft-bristled brush or a mop into the solution and wring it out thoroughly.
- Gently scrub the bluestone surface, working in small sections.
- Rinse the area thoroughly with clean water to remove any soap residue.
- Allow the surface to air dry or use a clean towel to blot it dry.
White Vinegar and Water
White vinegar is a natural and effective cleaning agent that can be used to remove dirt and stains from bluestone. Here’s how to use it:
- Mix 1 cup of white vinegar with 1 gallon of warm water.
- Dip a soft-bristled brush or a mop into the solution and wring it out thoroughly.

Abrasive materials, such as wire brushes or scrubbers, can scratch or damage bluestone. Instead, use soft-bristled brushes or sponges to clean the surface.
Avoid Using High-Pressure Washes
High-pressure washes can damage bluestone by dislodging the stone’s surface or forcing water into the stone’s pores. If you must use a pressure washer, make sure to keep the nozzle at least 12 inches away from the surface and use a wide fan tip to distribute the pressure.
Avoid Using Harsh Chemicals
Harsh chemicals, such as bleach or ammonia, can damage bluestone or discolor its surface. Instead, opt for mild soap and water or specialized cleaning products designed for natural stone surfaces.
Sealing Bluestone: An Additional Layer of Protection
While cleaning bluestone regularly is essential, sealing the stone can provide an additional layer of protection against stains and damage. Sealing bluestone can help to:
- Repel stains and spills
- Protect the stone from UV damage
- Reduce the risk of etching
- Make cleaning easier
There are different types of sealants available, including topical sealants, penetrating sealants, and enhancers. It’s essential to choose a sealant that is compatible with bluestone and follow the manufacturer’s instructions for application and maintenance.
Conclusion
Cleaning bluestone requires a gentle and nuanced approach to preserve its natural beauty and extend its lifespan. By understanding the properties of bluestone and using the right cleaning methods and products, you can keep your bluestone surfaces looking their best. Remember to avoid using acidic substances, abrasive materials, high-pressure washes, and harsh chemicals, and consider sealing your bluestone to provide an additional layer of protection. With proper care and maintenance, your bluestone surfaces can remain a stunning focal point for years to come.
What is Bluestone and Why is it so Popular?
Bluestone is a type of flagstone that is prized for its unique blend of blue-gray colors and durability. It is a popular choice for outdoor landscaping and hardscaping projects because of its elegant appearance, low maintenance requirements, and ability to withstand harsh weather conditions. Bluestone is also highly versatile and can be used for patios, walkways, pool decks, and even indoor flooring.
The popularity of bluestone can be attributed to its unique aesthetic appeal, which adds a touch of sophistication and elegance to any outdoor or indoor space. Additionally, bluestone is also extremely durable and can withstand heavy foot traffic, making it an ideal choice for high-traffic areas. With proper maintenance and cleaning, bluestone can last for decades, retaining its beauty and charm over time.
How Often Should I Clean My Bluestone?
The frequency of cleaning bluestone depends on the level of foot traffic and exposure to the elements. For high-traffic areas, it’s recommended to clean bluestone every 2-3 months to remove dirt and debris that can scratch the surface. For low-traffic areas, cleaning every 6-12 months is sufficient. It’s also important to clean bluestone immediately after spills or stains to prevent them from setting into the stone.
Regular cleaning can help prevent the buildup of dirt and stains, which can be difficult to remove if left unchecked. Additionally, cleaning bluestone regularly can help maintain its natural beauty and prevent the growth of mold and mildew. By establishing a regular cleaning schedule, you can keep your bluestone looking its best and extend its lifespan.
What is the Best Way to Clean Bluestone?
The best way to clean bluestone is to use a gentle, neutral-pH cleaner specifically designed for natural stone.

Instead, mix the cleaner with warm water, and apply it to the bluestone using a soft-bristled brush or mop. Avoid using excessive water, as it can seep into the stone and cause damage.
For more stubborn stains, you can use a solution of baking soda and water to create a paste, which can be applied to the stain and left to sit for 30 minutes before rinsing. It’s also important to dry the bluestone thoroughly after cleaning to prevent water spots from forming. By using the right cleaning products and techniques, you can effectively clean your bluestone without damaging it.
Can I Use Bleach to Clean Bluestone?
No, it’s not recommended to use bleach to clean bluestone. Bleach is a harsh chemical that can damage the stone or strip away its natural oils, causing it to become dull and discolored. In addition, bleach can also react with the minerals in bluestone, causing it to etch or become rough to the touch. Instead, stick to gentle, neutral-pH cleaners specifically designed for natural stone.
If you’re dealing with mold or mildew, it’s better to use a solution of oxygen bleach, which is gentler on the stone than chlorine bleach. However, it’s still important to follow the manufacturer’s instructions and take necessary safety precautions to avoid damaging the stone or harming yourself.
How Do I Remove Stains from Bluestone?
Removing stains from bluestone requires patience and the right techniques. For oil-based stains, use a solution of baking soda and oil to absorb the stain, followed by a gentle cleaning product to remove the residue. For acidic stains, use a solution of baking soda and water to neutralize the acid, followed by a gentle cleaning product to remove the residue.
For organic stains, such as those caused by plant or animal matter, use a solution of hydrogen peroxide and water to break down the stain, followed by a gentle cleaning product to remove the residue. Regardless of the type of stain, it’s important to act quickly and avoid using harsh chemicals or abrasive cleaners, which can damage the stone or push the stain deeper into the surface.
How Do I Seal Bluestone?
Sealing bluestone is an optional but highly recommended step to protect it from stains and spills. There are two types of sealers: topical sealers and penetrating sealers. Topical sealers create a barrier on the surface of the stone, while penetrating sealers absorb into the stone to protect it from within.
When choosing a sealer, make sure to select one that is specifically designed for bluestone and follow the manufacturer’s instructions for application. Apply the sealer to clean, dry bluestone, and allow it to dry according to the instructions. Keep in mind that sealers may need to be reapplied periodically to maintain their effectiveness.
Can I Use Pressure Washing to Clean Bluestone?
While pressure washing can be effective for cleaning bluestone, it’s not recommended as a regular cleaning method. Pressure washing can damage the stone or strip away its natural oils, causing it to become dull and discolored. Additionally, pressure washing can also push dirt and debris deeper into the stone, making it harder to clean in the long run.
If you must use pressure washing, make sure to use a wide fan tip and keep the nozzle at least 12 inches away from the stone to avoid damaging it. Use a low-pressure setting and avoid using hot water, as it can cause the stone to crack or become discolored. It’s also important to test the pressure washer on a small, inconspicuous area first to ensure it won’t damage the stone.
