Bluestone is a popular natural stone used in construction and landscaping due to its durability, unique texture, and attractive blue-gray coloration. While it can certainly stand the test of time, proper care and maintenance are essential to ensure that your bluestone surfaces continue to look their best. In this article, we will explore three effective methods for cleaning bluestone.

1. Routine Cleaning with Water and a Soft Bristle Brush

For everyday dirt and debris, routine cleaning is key. Follow these simple steps for a gentle yet effective clean:

a. Sweep or vacuum the bluestone surface to remove loose dirt, leaves, and other debris.

b. Fill a bucket with warm water.

c. With a soft bristle brush or broom, scrub the surface of the bluestone using the warm water in a circular motion.

d. Rinse the area thoroughly with clean water.

e. Allow the bluestone to air dry completely before using it again.

This method should be performed regularly to prevent the build-up of grime on your bluestone surfaces.

2. Deep Cleaning with Mild Detergents

Bluestone may occasionally require deeper cleaning than routine maintenance can provide when dealing with stubborn stains like algae, mold or mildew growth:

a. Choose a mild detergent that is safe for natural stone surfaces and mix it into a bucket of warm water according to the manufacturer’s instructions.

b. Sweep or vacuum the surface before beginning to remove any loose elements.

c. Apply the cleaning solution to the bluestone using a soft brush or broom – make sure not to use wire brushes or harsh scrubbers as these can damage the stone.

d. Let the solution sit for at least 15 minutes to break down stains but be mindful not to let it dry on the surface.

e. Scrub the area gently during this time if needed.

f. Thoroughly rinse the bluestone with clean water, making sure to remove all detergent residue.

g. Allow the surface to air dry completely before it is exposed to foot traffic.

3. Periodic Cleaning with a Pressure Washer

Pressure washing is an effective method to clean deeper groves and crevices which may not be reached with other cleaning methods. However, it is important to be mindful of the pressure settings used on your pressure washer so as not to damage the bluestone surface.

a. Set your pressure washer to a low-pressure setting (no higher than 1,300 PSI) or use a wide-angle spray nozzle attachment.

b. Sweep or vacuum the bluestone surface before you begin.

c. Work in small sections and hold the pressure washer nozzle at least 12 inches away from the stone, maintaining a consistent distance as you move across.

d. Be cautious of areas with loose mortar or joint sand – adjust your pressure as necessary to prevent further damage.

e. Allow the bluestone to air dry completely after pressure washing.

In conclusion, regular attention and care are essential for maintaining the beauty and integrity of your bluestone surfaces. It is crucial that you choose appropriate cleaning methods and products designed specifically for use on natural stone. With these three methods in mind, you can be confident that you are keeping your bluestone looking pristine for years to come.
