Use this step-by-step guide below to properly and safely clean your concrete patio with a pressure washer.

How To Clean A Concrete Patio

Whether you plan to host parties on your patio or are simply looking for a quiet space, a good cleaning can dramatically improve its appearance. Follow the cleaning steps outlined below.

Step 1. Prepare The Area

• Prepare your patio before breaking out your pressure washer.
• Start by removing any furniture, planters, or decor.
• Use either a stiff broom or leaf blower to sweep away any debris from the patio.
• Doublecheck for any stains, cracks, or damage.
• Locate any high-stain areas, if applicable.

Step 2. Pre-Treat Stains

• If you spot a grease spill, you’ll want to treat that before moving forward with this task.
• A degreaser or dish soap with baking soda paste could be used for removal.
• A water and vinegar solution, bleach mixture, or mold-killing detergent works best for mold, mildew, or algae.
• Commercial rust removers can deal with rust stains.
• Pet and food stains call for the use of an enzymatic cleaner.

Step 3. Protect Surrounding Area

• Protecting the surrounding area is paramount, at this time.
• Tarps or even heavy-duty plastic sheeting can cover patio doors, siding, windows, and nearby plants.

Step 4. Configure The Pressure Washer

• Start by attaching the proper nozzle onto your pressure washer.
• 25-degree nozzles are ideal for general cleaning purposes.
• 15-degree nozzles, meanwhile, work more aggressively on grime.
• Zero-degree nozzles have been known to etch the concrete.
• Start the pressure at a lower setting before working to a higher pressure.
• Use a concrete-safe cleaner if you wish to add the use of a detergent.

Step 5. Pressure Wash The Patio

• Start at the highest point of the concrete patio.
• Work your way away from the walls, making sure to direct the dirty water down and away from the home.
• Try to use an overlapping pattern and keep the nozzle moving consistently.
• Maintain the nozzle at a safe and consistent distance to avoid any potential streaks.

Step 6. Seal The Patio

• This step is optional, but sealing will certainly help protect your patio for the future.
• Seal the patio once it is completely clean and dry.
• Sealing will protect from any future stains, damage, or water absorption.

Conclusion

Some routine maintenance can save you a whole lot of cleaning as soon as the weather gets nice. To keep your patio looking great year-round, do the following between cleanings:

• Rinse off any spills or messes.
• Sweep consistently.
• Lift sunken slabs.
• Caulk any joints or cracks.
