Next, remove any obstacle in the area to give you enough space to clean every part of the patio. You may need to remove furniture and decorations. After that, use the broom to sweep the entire area to remove dirt and other debris.

Step-by-Step Guide to Cleaning a Flagstone Patio

Cleaning a flagstone patio is a simple process every homeowner can complete quickly. However, it requires a detailed procedure to ensure every part of the patio is cleaned properly. That said, here are the steps you need to follow when cleaning a patio:

Step 1: Gather the Tools and Materials

You will need the following:

  • A bucket: To mix and hold the cleaning solution

  • A mild detergent or a stone cleaner: Do not worry if you don’t have these specialized cleaning solutions since you can use dish soap.

  •  Stiff-bristle brush: This one will help you scrub the area after applying the cleaning solution.

  • Garden hose or a pressure washer: To help you rinse off the cleaning solution and thoroughly remove debris and stains on the patio surface.

  • Sealant (optional): You will need this to seal the area to protect the flagstone from tough stains and UV lights.

  • Inspecting for tough stains: This is a critical process as it helps you know the type of cleaning solution you need for the job. Remember that tough stains require specialized solutions.

  • Identifying cracks or loose stones: Checking for cracks or loose stones is essential as it helps prepare for replacement repairs. 

Step 3: Cleaning the Patio

Follow these steps to clean the entire patio:

  • Fill the bucket with warm water and add a cleaning solution. The cleaning solution you need will depend on the type of stains on the patio surface. For normal debris and dirt, you can use a soap dish. For tough stains like oil or rust, you will need to use white vinegar or ammonia.

  • Dunk the stiff bristle brush in the cleaning solution and apply to the entire area. Start from one corner to the other to ensure you don’t leave out any area.

  • Allow the solution to sit for at least 30 minutes. This will help loosen the tough stains on the flagstone.

  • Scrub the patio. After 30 minutes, take the bristle brush and start scrubbing the area. Again, start from one corner to the other to avoid confusion. Also, scrub gently to avoid damaging the surface of the flagstone.

  • Rinse with clean water. Use a garden hose or a pressure washer to rinse the soap solution. When using a pressure washer, adjust the pressure to around 1000 to 1500 Psi to avoid damaging the pavers.

  • Allow to dry and seal. After cleaning and ensuring the entire area is clean, allow it to dry, and apply an ideal sealant. Still, you can avoid applying the sealant if the patio area does not receive much UV light. That is it! You have cleaned your patio and it's now ready for use.
