Can You Power Wash Stone? The Ultimate Guide

If you're looking for an easy and affordable way to clean your stone surfaces, power washing is a great option. Power washing can be used on a variety of surfaces, including concrete, brick, stone, and more. In this guide, we will teach you everything you need to know about power washing stones!

What is power washing and how does it work?

Power washing is a method of cleaning that uses high-pressure water to remove dirt, grime, and other build-ups from surfaces. It is an effective way to clean a wide range of materials, including concrete, brick, asphalt, stone, wood, and vinyl. Power washing is often used to clean driveways, sidewalks, patios, decks, fences and other outdoor areas. It can also be used to remove paint, stains, and mildew from a variety of surfaces.

Power washing machines are typically powered by gas or electricity. The pressure of the water is generated by a pump, which forces the water through a high-pressure hose. A nozzle is attached to the end of the hose, and this is used to direct the stream of water to the surface that is being cleaned.

What are the benefits of power washing?

Power washing is a handy way to clean all surfaces. Apart from removing dirt, grime, mildew, and other build-ups from the surface, power washing can also restore the color and beauty of the surfaces. In addition, power washing can help to prep surfaces for painting or staining. And because it uses high-pressure water instead of chemicals, power washing is an environmentally friendly way to clean. So if you're looking for a thorough way to clean your home or business, power washing may be the solution for you.

Can you power wash stone?

Pressure washing is an efficient way to clean many different types of surfaces, but you may be wondering if it is safe to use on stone. The answer is that it depends on the type of stone. For example, natural stone such as granite or marble can be damaged by power washing, as the high pressure can strip away the protective sealant. In contrast, man-made stones such as concrete or brick are much more resistant to damage from power washing. So before you break out the pressure washer, be sure to check what type of stone you are working with. With a little bit of care, you can keep your stone surfaces looking clean and beautiful for years to come.

How to power wash stone surfaces?

Before power washing a stone surface, it is important to clear away any loose dirt or debris. Once the surface is clear, you can begin power washing.

  • Start by setting the pressure washer to a low setting and gradually increase the pressure until you find the right setting for your particular stone surface.

  • Remember to hold the wand at a consistent distance from the surface and move it in a smooth, circular motion.

  • It is also essential to use suitable detergent for the job. Stone surfaces are porous and can be damaged by harsh chemicals, so it is important to use a mild detergent that is specifically designed for use with a power washer.

  • When power washing a stone surface, always start at the top and work your way down. This will help prevent streaking and ensure that you don't miss any spots.

With a little bit of care and attention, power washing can be an effective way to clean your stone surfaces.

Tips and Tricks for power washing stone surfaces

Power washing is a great way to clean everything from sidewalks to decks. But it's also important to know how to use a power washer safely and effectively. Here are a few tips and tricks:

1. Choose the right power washer

Power washing stone surfaces can be an excellent way to keep them looking clean and new. However, it's important to choose the right power washer for the job. The general rule of thumb is to choose a power washer with a psi (pounds per square inch) rating that is twice as high as the psi of the surface you're cleaning.

For example, if you're power washing a stone surface with a psi rating of 3000, you'll want to choose a power washer with a psi rating of 6000 or higher. This will ensure that you're able to safely and effectively remove all dirt and grime without damaging the surface.

2. Start with a low setting

When it comes to power washing stone surfaces, always start with a low setting and gradually increase the pressure until you find the right setting for your particular surface. This will help prevent any damage to the surface as well as any potential injuries.

If you start on a high setting, you run the risk of chipping or cracking the surface, which can be both unsightly and difficult to repair. So take your time, start low, and work your way up until you find the perfect pressure setting for the job at hand. And, if you're not sure what settings to use, test on an inconspicuous area first.

3. Use a wide spray pattern

When power washing stone surfaces, it is essential to use a wide spray pattern. This will help avoid striping or damaging the surface. By using a wide spray pattern, you will be able to evenly distribute the pressure and prevent any concentrated areas of pressure that could damage the stone.

Additionally, using a wide spray pattern will help to evenly remove dirt and debris from the surface of the stone. When power washing, always start with the widest spray pattern and then adjust as needed. This will help ensure that you are safely and effectively cleaning your stone surfaces.

4. Move wand in a sweeping motion

If you're power washing a stone surface, it's important to move the wand in a sweeping motion. Keeping it in one spot for too long can etch or even burn the surface. By moving it around, you'll avoid any damage and end up with a clean surface. Just be sure to hold the wand at a consistent distance from the surface so that you don't miss any spots. With a little care, you'll have a clean surface in no time.

5. Release trigger when finished

As any avid gardener knows, stone surfaces can be challenging to clean. Dirt and debris can quickly build up, making it difficult to remove without the use of a power washer. However, if you are not careful, you can easily damage your stone surfaces with a power washer.

To help prevent this, always remember to release the trigger before turning off the power washer. This will help to prevent damage to the pump and will ensure that your stone surfaces are properly protected. With a bit of care, you can keep your stone surfaces looking new for years to come.

By following these tips, you can safely and effectively clean your stone surfaces without any damage.


Power washing stone surfaces can be a great way to keep them looking new and last for years, but it's important to use the right power washer and technique. The tips in this blog post should help you safely clean your stones without damaging any of those precious details. So grab your power washer and get started!
