Dive in to find out how to clean your patio.

The Soapy Water Method

For those who prefer a non-chemical patio cleaner, the soapy water method is a simple solution that can be used on just about any paving material.


  1. Preparation: Begin by removing any patio furniture and brush off loose debris from the patio surface. This ensures that the cleaning solution can work directly on the stubborn dirt.

  2. Mixing the Solution: In a large bucket, combine warm tap water with a little washing up liquid squirt. The resulting soapy suds should be enough to cover the whole patio.

  3. Scrubbing Routine: Using a stiff broom, scrub diagonally across the paving slabs. This splashing and scrubbing routine helps in ensuring the dirt and debris lift effectively from the patio surface.

  4. Rinsing: Once scrubbed, rinse the area with clean water using a garden hose or watering can. Ensure there's no standing water left on the slabs.

The Vinegar and Water Solution Method

White vinegar is a versatile cleaning agent that's environmentally friendly and effective for cleaning patio slabs.


  1. Mixing the Solution: Combine equal parts of white vinegar and warm water in a bucket. For dirtier patios or more stubborn stains, you might want to use slightly more vinegar or just spot treat heavier stains with a stronger solution.

  2. Application: Pour the vinegar and water solution over the patio slabs, ensuring even coverage.

  3. Scrubbing: Just like the soapy water method, scrub diagonally using a stiff brush. The acidity of the vinegar helps in tackling stubborn discolouration stains.

  4. Rinsing: Rinse off the dirty water using cold water. Ensure no solution remains on the slabs to prevent any potential damage.

Pressure Washer Method

For those tough cleaning jobs, a pressure washer is the intense patio cleaning method of choice. It's especially effective for larger patios and high traffic outdoor areas.


  1. Safety First: Before you plug in your pressure washer plug, ensure you wear protective clothing. The jet stream from pressure washers can be very powerful.

  2. Preparation: Remove any patio furniture and brush off any loose jointing compound or debris. Ensure you have a drainage point to prevent any pooling of water.

  3. Pressure Washing: Fill the detergent chamber of your pressure washer with a suitable pressure washer detergent. Start washing from one end of the patio, moving systematically to ensure even cleaning.

  4. Rinsing and Sealing: Once done, rinse the patio with clean water. For added protection, consider applying a patio sealant.

The Environmentally Friendly Cleaning Solution

For those conscious about the environment, there are patio cleaners that are both effective and environmentally friendly. These solutions often avoid harsh chemicals, making them safe for your garden and the surrounding ecosystem.


  1. Preparation: As always, start by clearing your patio of furniture and sweeping away any loose debris.

  2. Mixing the Solution: In a bucket, combine warm water with a squirt of washing up liquid. For an added boost, you can add a splash of white vinegar or bicarbonate soda adding 1 to 5 tablespoons to 10 litres of water.

  3. Application: Spread the cleaning solution across the patio slabs, ensuring even coverage. Allow to dwell for 10 to 15 mins. In hot conditions keep surface wet to avoid the solution drying out.

  4. Scrubbing Routine: Engage in a thoroughly scrubbing to agitate, focusing on stubborn dirt and any discolouration stains.

  5. Rinsing: Use a garden hose to rinse away the soapy solution and any lifted dirt, ensuring the patio is free from any residue.

The Bleach Cleaning Method

Bleach is a potent and cost-effective cleaning agent that can effectively tackle dirt, black spot, moss, and algae on patio slabs, suitable for various types of paving like natural stones or concrete​​.


  1. Remove Obstacles: Clear the patio of furniture, plant pots, and decorative items to create a workspace free of obstructions​​.

  2. Sweep the Patio: Use a stiff brush to sweep away loose debris and dirt. This step exposes the slab surface for effective bleach application​​.

  3. Safety First: Wear protective gloves and safeguard nearby sensitive plants from bleach splashes​​.

  4. Prepare the Bleach Solution: Mix one part bleach with five parts warm water in a bucket. For tougher stains, increase the bleach concentration and possibly add some soapy water​​.

  5. Test the Solution: Before applying it to the entire area, test the bleach solution on a small, inconspicuous patio area to avoid discoloration​​.

  6. Wet the Surface: Lightly moisten the patio slabs with a garden hose or watering can before applying the bleach for even distribution and better penetration​​.

  7. Apply the Bleach: Evenly distribute the bleach solution across the patio, focusing on stained areas or spots with algae and moss​​.

  8. Allow Time to React: Let the solution sit for a few minutes without drying out completely to break down dirt and stains effectively​​.

  9. Scrubbing: Use a stiff brush to scrub the slabs, focusing on grout lines and edges. For tough stains, apply more effort or reapply the bleach solution before scrubbing again​​.

  10. Rinsing Off: Rinse the patio thoroughly with clean water, ensuring no bleach solution remains on the slabs​​.

Maintaining Your Patio

Regular maintenance can prevent the build-up of dirt and reduce the need for intense patio cleaning methods.


  • Regular Sweeping: Regularly brush away dirt, leaves, and other debris. This not only keeps the patio looking tidy but also prevents the growth of moss and weeds.

  • Prompt Stain Removal: If you spill something on your patio, clean it up immediately. This prevents the formation of stubborn stains.

  • Re-sealing: Consider re-sealing your patio slabs every few years. A good sealant protects the slabs from stains and extends their lifespan.

  • Avoiding Harsh Chemicals: Always opt for environmentally friendly or non-chemical patio cleaner solutions when possible. These are gentler on your paving stones and the environment.

When to Seek Professional Help

While DIY methods can be effective, there are times when it might be best to call in the professionals, especially if your patio has not been cleaned for several years or is showing signs of significant wear and tear.

Signs you might need professional help:

  • Deep-seated or very stubborn stains that don't respond to regular cleaning methods.

  • Significant moss, algae, or weed growth.

  • If the patio slabs are damaged or loose.
