How to clean flagstone

Flagstone is a beautiful and durable natural stone that can add a touch of elegance to any outdoor space. However, over time, it can become dirty and stained, detracting from its natural beauty. Fortunately, cleaning flagstone is a relatively simple task that can be accomplished with a few basic tools and some elbow grease. Here are some expert tips to help you keep your flagstone looking pristine for years to come.

Start with a gentle cleaning solution.

When it comes to cleaning flagstone, it’s important to start with a gentle cleaning solution. Harsh chemicals can damage the stone and cause discoloration. Instead, opt for a mild detergent or a solution of water and vinegar. Mix the solution in a bucket and apply it to the flagstone with a soft-bristled brush. Scrub gently, being careful not to scratch the surface of the stone. Rinse thoroughly with clean water and allow the stone to dry completely before moving on to the next step.

Use a soft-bristled brush or pressure washer.

When it comes to cleaning flagstone, using a soft-bristled brush or pressure washer can be effective in removing dirt and grime. However, it’s important to use these tools with caution. A pressure washer set too high can damage the stone, while a brush with bristles that are too stiff can scratch the surface. Always test a small, inconspicuous area first and adjust your technique as needed. And remember, never use a wire brush or any abrasive materials on flagstone.

Avoid harsh chemicals and acidic cleaners.

When it comes to cleaning flagstone, it’s important to avoid harsh chemicals and acidic cleaners. These can damage the stone and cause discoloration or etching. Instead, opt for a mild, pH-neutral cleaner specifically designed for natural stone. You can also make your own cleaner by mixing warm water with a small amount of dish soap or vinegar. Just be sure to rinse the stone thoroughly after cleaning to remove any residue.

Seal your flagstone to protect it from stains and damage.

One of the best ways to protect your flagstone from stains and damage is to seal it. A high-quality sealer will help to repel water, oil, and other liquids, preventing them from penetrating the stone and causing discoloration or damage. Be sure to choose a sealer that is specifically designed for natural stone and follow the manufacturer’s instructions carefully. It’s also important to reapply the sealer periodically to ensure continued protection.

Regularly sweep and clean your flagstone to prevent buildup.

One of the most important things you can do to keep your flagstone looking its best is to regularly sweep and clean it. Dirt, debris, and other materials can build up on the surface of the stone over time, causing discoloration and potentially even damage. Use a soft-bristled broom or a vacuum with a soft brush attachment to remove loose dirt and debris, and then clean the stone with a mild detergent and water. Avoid using harsh chemicals or abrasive cleaners, as these can damage the stone.
