How to Clean Driveway Bricks
By Driveways Weymouth
A brick driveway is one of the most attractive and durable choices for homeowners across the UK. Its timeless look, variety of colour tones, and strong surface make it a favourite for both traditional and modern homes. However, like all outdoor surfaces, driveway bricks are constantly exposed to weather, mud, vehicle fluids, and algae growth. Over time, these can dull the colour, make the bricks slippery, and even lead to structural wear if left untreated.
Keeping your brick driveways cleaning doesn’t just improve your home’s kerb appeal, it also protects your investment. In this guide, Driveways Weymouth explains how to properly clean driveway bricks, remove stains, and keep the surface looking its best all year round.
1. Why Regular Brick Driveway Cleaning Matters
Driveway bricks are porous, which means they can easily absorb dirt, oil, and water. In the UK’s damp climate, this also encourages the growth of moss, lichen, and algae, particularly in shaded or north-facing areas.
If not cleaned regularly, grime builds up in the joints and between bricks, leading to:
- Discolouration – bricks lose their natural tone or appear patchy.
- Weed growth – soil and organic debris allow weeds to take root in the gaps.
- Surface erosion – trapped dirt and salt can wear down the top layer of the bricks.
- Slippery surfaces – moss and algae make the driveway unsafe to walk on, especially in winter.
A well-maintained driveway not only enhances the appearance of your property but also increases its longevity and value.
2. Step-by-Step Guide to Cleaning Brick Driveways
Whether you’re cleaning the surface yourself or preparing for professional driveway cleaning, following a methodical approach ensures the best results.
Step 1: Clear the Surface
Begin by removing all loose debris. Sweep the driveway thoroughly with a stiff broom to clear away leaves, dust, and small stones. This allows you to see the areas that need extra attention.
Tip: Use a leaf blower or garden vacuum for faster results, especially before applying any water-based cleaner.
Step 2: Apply a Suitable Cleaning Solution
You can choose between a commercial brick cleaner or a homemade solution depending on the level of dirt.
- For light dirt and algae, mix warm water with washing-up liquid or a small amount of white vinegar.
- For oil or fuel stains, use a degreasing detergent specifically made for brick or block paving.
- For moss and lichen, use a specialist biocidal cleaner that kills spores without damaging the surface.
Apply your chosen cleaner using a watering can or pump sprayer, ensuring even coverage. Leave it to sit for 10–15 minutes to allow the solution to break down grime.
Step 3: Scrub or Pressure Wash
After the cleaner has soaked in, scrub the surface using a stiff-bristled brush to lift dirt and stains. For larger areas, a pressure washer can save time, but use it carefully.
Important tips for pressure washing brick driveways:
- Use a medium pressure setting (around 1500–2000 PSI) to avoid damaging the bricks or removing joint sand.
- Keep the nozzle at a 45° angle and about 30 cm from the surface.
- Work in small sections to ensure even cleaning.
- Rinse thoroughly with clean water to remove all residue.
Step 4: Remove Weeds and Re-Sand the Joints
After cleaning, inspect the joints between bricks. If weeds or moss were removed, there may be empty gaps where jointing sand has washed away. Once the surface is fully dry, refill these gaps with kiln-dried sand.
Brush the sand into the joints using a soft broom, this not only stabilises the bricks but also prevents future weed growth.
Step 5: Apply a Sealant (Optional but Recommended)
Applying a brick sealant provides long-lasting protection against stains, water damage, and moss regrowth.
Choose a breathable, UV-resistant sealer suitable for clay or concrete pavers. Apply it evenly with a roller or sprayer, ensuring the surface is clean and completely dry. Sealing should be done on a warm, dry day to allow proper curing.
A sealed driveway is easier to clean, more resistant to discolouration, and retains its original colour for much longer.
3. Removing Stubborn Stains from Brick Driveways
Different stains require different treatments. Here’s how to tackle the most common ones found on UK driveways:
- Oil and grease stains: Use a degreasing cleaner or sprinkle cat litter or baking soda over fresh spills to absorb oil before scrubbing.
- Rust stains: Use a mild brick-safe rust remover, avoid acidic cleaners that may etch the surface.
- Moss and algae: Apply a biocide or moss killer and leave it for several days before rinsing.
- Tyre marks: Use a mild detergent and stiff brush; avoid harsh solvents that can discolour bricks.
For deeply embedded or large-scale stains, Driveways Weymouth can use professional-grade steam or rotary surface cleaners to lift dirt effectively without causing damage.
4. Preventing Future Build-Up
After cleaning your brick driveway, regular upkeep will make future maintenance much easier. Here’s how to keep it looking spotless:
- Sweep weekly to prevent dust and organic matter build-up.
- Rinse monthly with a hose or light pressure washer.
- Treat seasonally with a moss and algae inhibitor.
- Top up jointing sand after heavy rain or cleaning.
- Re-seal every 2–3 years for maximum protection.
Simple, consistent care keeps your driveway vibrant and safe for years to come.
