You do not need a pressure washer to get a clean patio. With the right approach, a stiff brush and some elbow grease can achieve excellent results.
What you need
- Stiff bristle brush or deck brush
- Bucket
- Watering can or hose
- Cleaning solution (see below)
- Rubber gloves
Basic cleaning method
- Sweep the patio to remove loose debris, leaves and dirt.
- Wet the surface with water.
- Apply your cleaning solution and leave for 10-15 minutes.
- Scrub with a stiff brush, working in sections.
- Rinse thoroughly with clean water.
- Repeat on stubborn areas if needed.
DIY cleaning solutions
For general dirt and algae:
Mix washing-up liquid with warm water (a good squirt per bucket). This is gentle and effective for regular cleaning.
For algae and moss:
Mix one part white vinegar to four parts water. Vinegar is mildly acidic and kills algae. Avoid using on limestone or other acid-sensitive stone.
For stubborn stains:
Make a paste of bicarbonate of soda and water. Apply to stains, leave for 15 minutes, then scrub and rinse.
For heavy algae and black spots:
Use a proprietary patio cleaner containing bleach or sodium hypochlorite. Follow the product instructions carefully and protect nearby plants.
Removing specific stains
- Oil and grease: Cover with cat litter or sand to absorb, then scrub with washing-up liquid.
- Rust: Use a rust remover product or try lemon juice and salt.
- Bird droppings: Soak with water, then scrub with soapy water.
- Moss in joints: Scrape out with an old knife or patio knife, then treat with moss killer.
Tips for better results
- Clean on a dry day so the patio dries quickly afterwards.
- Work in sections so the cleaning solution does not dry out before you scrub.
- Use a long-handled brush to save your back.
- Rinse thoroughly – leftover cleaning solution can leave marks.
Preventing future build-up
- Sweep regularly to prevent debris accumulating.
- Trim back overhanging plants that shade the patio and encourage algae.
- Apply a patio sealer after cleaning to protect the surface.
- Treat with algae preventer in autumn before the wet season.
Caution: Never mix bleach with vinegar or other acids – it creates toxic fumes. Use one or the other, not both.
