Are you tired of looking at a dull, dirty bluestone patio? Do you want to restore its original beauty and make it sparkle like new? Power washing is a popular cleaning method for many outdoor surfaces, but can it be used on bluestone patios? In this article, we’ll explore the benefits and risks of power washing a bluestone patio, and provide you with the knowledge to make an informed decision.
What is Bluestone?
Before we dive into the world of power washing, let’s start with the basics. Bluestone is a type of flagstone that is commonly used for outdoor paving, walkways, and patios. It’s a metamorphic rock that is known for its durability, versatility, and attractiveness. Bluestone is often used in landscaping projects because it’s resistant to weathering, erosion, and heavy foot traffic.
Bluestone patios can add a touch of elegance and sophistication to any outdoor space. However, like any other outdoor surface, they can become dirty and stained over time, which can detract from their beauty.
Benefits of Power Washing a Bluestone Patio
Power washing is an effective way to clean bluestone patios because it uses a high-pressure stream of water to blast away dirt, grime, and other contaminants. Here are some benefits of power washing a bluestone patio:
Deep Cleaning
Power washing can penetrate deep into the pores of the bluestone, removing dirt, grime, and other substances that can accumulate over time. This deep cleaning can restore the natural beauty of the bluestone and make it look like new.
Fast and Efficient
Power washing is a fast and efficient way to clean a bluestone patio. It can save you time and effort compared to traditional cleaning methods, such as scrubbing or sweeping.
Effective at Removing Stains
Power washing can be effective at removing stubborn stains from bluestone patios. It can lift dirt and grime out of the stone, leaving it clean and free of discoloration.
Risks of Power Washing a Bluestone Patio
While power washing can be beneficial for cleaning bluestone patios, there are also some risks to consider:
Damage to the Stone
If not done properly, power washing can damage the bluestone. The high-pressure stream of water can etch the stone, creating scratches and marks that can reduce its appearance.
Discoloration
Power washing can also cause discoloration on bluestone patios. If the wrong cleaning products are used, they can leave streaks or marks on the stone.
Sealant Damage
If your bluestone patio has a sealant applied, power washing can damage or remove it. This can leave the stone unprotected and vulnerable to further damage.
Tips for Power Washing a Bluestone Patio
If you’ve decided to power wash your bluestone patio, here are some tips to follow:
Use the Right Equipment
Use a power washer with a wide fan tip (at least 25 degrees) to prevent damage to the stone. A wide fan tip will also help to distribute the pressure more evenly, making it less likely to damage the stone.
Use the Right Cleaning Solution
Use a mild cleaning solution that is specifically designed for cleaning bluestone patios. Avoid using harsh chemicals or abrasive cleaners, as they can damage the stone or strip away its natural oils.
Keep the Pressure Low
Keep the pressure low (less than 1,000 PSI) to avoid damaging the stone. Higher pressures can etch the stone, creating scratches and marks.
Use Wide, Gentle Passes
Make wide, gentle passes over the patio, working in sections to clean the entire area. Avoid using a back-and-forth motion, as this can create scratches on the stone.
Test a Small Area First
Before power washing the entire patio, test a small area first to ensure that the cleaning solution and pressure won’t damage the stone.
Alternative Cleaning Methods for Bluestone Patios
If you’re concerned about the risks of power washing your bluestone patio, there are alternative cleaning methods you can use:
Sweeping and Scrubbing
Sweeping and scrubbing are effective ways to clean bluestone patios without using power washing. Use a soft-bristled broom to sweep away dirt and debris, and then scrub the patio with a mild cleaning solution and a soft-bristled brush.
Pressure Washing with a Lower Pressure
If you still want to use a pressure washer, consider using a lower pressure (less than 500 PSI) to clean your bluestone patio. This can be a safer option that still provides effective cleaning.
Conclusion
Power washing can be an effective way to clean bluestone patios, but it’s essential to do it correctly to avoid damaging the stone. By following the tips outlined above and taking the necessary precautions, you can restore the natural beauty of your bluestone patio and make it sparkle like new. Remember to always test a small area first and use the right equipment and cleaning solution to ensure a safe and effective cleaning process.

Is Power Washing Safe for Bluestone Patios?
Power washing can be safe for bluestone patios if done correctly. However, it’s essential to take the necessary precautions to avoid damaging the stone or surrounding landscape. Bluestone is a type of flagstone that is known for its durability, but it can still be susceptible to damage from high-pressure water jets.
To ensure safety, start by testing the power washer on a small, inconspicuous area to check for any damage. Use a wide-angle spray tip and keep the nozzle at least 12 inches away from the surface. Avoid using high-pressure settings, as they can etch or pit the stone. Additionally, use a low-pressure setting and a wide fan tip to distribute the pressure more evenly.
What Is the Best Way to Prepare My Bluestone Patio for Power Washing?
Before power washing your bluestone patio, it’s essential to prepare the area to avoid any damage or accidents. Start by clearing the patio of any furniture, plants, or other items that could get in the way or be damaged by the high-pressure water.
Sweep the patio to remove any loose debris, and then mix a solution of trisodium phosphate (TSP) with warm water to create a cleaning solution. Apply the solution to the patio using a soft-bristled broom, working in sections to clean the entire area. Allow the solution to sit for 10-15 minutes before rinsing with a garden hose. This will help loosen dirt and grime, making the power washing process more effective.
What Is the Recommended Pressure Setting for Power Washing a Bluestone Patio?
The recommended pressure setting for power washing a bluestone patio is typically between 1,000 and 1,500 pounds per square inch (PSI). This setting is gentle enough to remove dirt and grime without damaging the stone.
However, it’s essential to consider the condition of your bluestone patio before power washing. If the patio is old or shows signs of wear, it may be best to start with a lower pressure setting and gradually increase as needed. It’s also important to keep the nozzle at least 12 inches away from the surface to avoid concentrating the pressure in one area.
Can I Use a High-Pressure Nozzle to Remove Tough Stains on My Bluestone Patio?
While it may be tempting to use a high-pressure nozzle to remove tough stains on your bluestone patio, it’s generally not recommended. High-pressure nozzles can etch or pit the stone, causing permanent damage.
Instead, try using a gentle cleaning solution and a soft-bristled brush to scrub the stained area. If the stain is particularly stubborn, you can try using a poultice or a stain-removing product specifically designed for bluestone. Always follow the manufacturer’s instructions and test the product on a small, inconspicuous area before applying it to the entire patio.
How Often Should I Power Wash My Bluestone Patio?
The frequency of power washing your bluestone patio will depend on several factors, including the amount of foot traffic it receives, the local climate, and the amount of debris that falls on the patio. As a general rule, it’s recommended to power wash your bluestone patio every 6-12 months, or as needed.
Keep in mind that power washing too frequently can damage the stone or strip away its natural sealant. Instead, focus on regular cleaning and maintenance to keep your patio looking its best. Sweep the patio regularly, and clean up spills immediately to prevent stains from forming.
Can I Power Wash My Bluestone Patio in Direct Sunlight?
It’s generally not recommended to power wash your bluestone patio in direct sunlight, as this can cause the water to evaporate too quickly and create streaks or spots on the stone. Instead, try to power wash your patio in the early morning or late afternoon when the sun is not directly overhead.
Additionally, try to power wash your patio in sections, working in a consistent pattern to avoid creating streaks or patterns on the stone. This will help ensure a more even cleaning and prevent any damage to the patio.
Is It Necessary to Seal My Bluestone Patio After Power Washing?
Yes, it’s highly recommended to seal your bluestone patio after power washing to protect it from stains and damage. Power washing can strip away the natural sealant on the stone, making it more susceptible to stains and damage.
Apply a bluestone-specific sealant to the patio using a foam roller or soft-bristled brush, working in sections to cover the entire area. Follow the manufacturer’s instructions and apply the recommended number of coats to ensure maximum protection.
