Step 4: Addressing Stubborn Stains and Dirt


Tackling Stains


Even with a pressure washer, some stains on a dirty patio may persist. In such cases, using a patio cleaner or a mixture of warm water and a mild detergent can help. Apply the solution to the stains, and use a scrubbing brush to gently work it into the surface. After scrubbing, use the pressure washer again to rinse off the cleaning solution. For extremely stubborn stains, consider a power wash with hot water. This technique, uses heated hot water to break down tough stains more effectively.


While this guide focuses on pressure washing a.k.a jet washing, it's worth noting the benefits of using a power washer for certain tough cleaning tasks. Power washing with hot water can be more effective for removing oil, grease, and other stubborn substances. The heated water from a power washer helps to break down these tough stains, making them easier to rinse away. Remember, power washing is a more specialized technique, so it might require professional handling or equipment designed specifically for hot water use.



Removing Algae, Moss, Black Spot and Grime


Black spot, Algae and moss can be particularly challenging to remove. If your patio has these issues, consider using a specialised patio cleaner designed to target algae and moss. Be sure to follow the manufacturer's instructions for the best results.



Step 5: Rinsing and Drying the Patio


After pressure washing, it’s important to rinse the patio with clean water to remove any remaining dirt or cleaning agents. Once rinsed, allow the patio to dry completely. This step is essential, especially if you plan to apply a sealant later.


Step 6: Post-Cleaning Care


Inspecting and Protecting the Patio


After cleaning, inspect your patio for any damage and make necessary repairs. To protect your patio from future stains and weather damage, consider applying a sealant. This can also enhance the appearance of natural stone or concrete slabs.


Returning Furniture and Decorations


Once the patio is dry and any sealant has cured, you can return your garden furniture and decorations to their places. Ensure that the furniture is clean before placing it back on the patio to avoid transferring dirt back onto the clean slabs.


Safety Tips for Using a Pressure Washer


When using a pressure washer, safety should be a top priority. Always wear safety goggles to protect your eyes from flying debris. Ensure that the water supply is steady and that all connections are secure to avoid leaks.


When operating the pressure washer, use both hands and engage the trigger gun carefully to control the powerful jet of water. Be mindful of your surroundings, especially if there are plants or delicate surfaces nearby that could be damaged by high pressure.


The Benefits of a Well-Maintained Patio


A well-maintained patio not only enhances the look of your outdoor space but also creates a welcoming environment for relaxation and entertainment. With the right pressure washer, safety measures, and aftercare, you can keep your patio in pristine condition year-round.


Remember, whether you’re dealing with stains on natural stone or simply looking to refresh your patio surface, pressure washing is a reliable and efficient solution.
