What You'll Need Before You Start

Manual scrubbing with the correct tools and cleaning solutions can be remarkably effective against algae, lichen, organic growth, and stubborn staining. This guide from Refresh Revive Exterior Cleaning walks you through every stage of the process, from initial debris removal through to post-cleaning sealing, so your driveway comes out looking genuinely restored rather than just damp.

Tools Checklist

Gather everything below before you begin:

Stiff-bristled brush (long-handled outdoor broom with stiff nylon bristles for large areas)
Smaller stiff-bristled hand brush for edges, joints, and corners
Wire brush for stubborn lichen on concrete or stone (use with care on softer surfaces)
Two buckets (one for solution, one for clean rinse water)
Garden hose with an adjustable nozzle, or access to a standpipe
Pump sprayer for even chemical application
Stiff-bladed garden scraper or weeding tool
Dustpan and brush or a leaf blower for dry debris removal

Protective Equipment

Driveway cleaning products are classified as hazardous substances under the Control of Substances Hazardous to Health Regulations 2002. Personal protective equipment is not optional.

Chemical-resistant gloves (nitrile or rubber, not fabric)
Safety goggles or a face shield
Old clothing or a waterproof apron
Closed-toe, non-slip footwear
A face mask rated for vapours if working in enclosed or poorly ventilated spaces

COSHH Driveway Cleaning Safety: What You Must Know First

COSHH driveway cleaning safety protects you, your family, your neighbours, and the environment from real harm. The Control of Substances Hazardous to Health Regulations 2002 require anyone using hazardous cleaning chemicals to understand the risks before they begin.

Every cleaning product must be applied strictly in accordance with its product label and safety data sheet. Do not exceed recommended dilution rates. Do not apply products on a windy day that could carry spray onto neighbouring gardens, vehicles, or planted areas. Do not allow surface runoff to enter drains or watercourses without checking whether the product is approved for that use, as some biocidal treatments are subject to restrictions under the Health and Safety Executive biocidal products regulation guidance.

Watch Out Never mix two cleaning products together. Combining a bleach solution with any other chemical, including common household cleaners, can produce toxic gases. Always follow the product label and safety data sheet. This is not a precaution to skip.

Apply cleaning agents only in dry weather. Wet surfaces dilute the product and reduce contact time, making treatment less effective and increasing runoff risk. Protect adjacent planted areas and lawns by covering them with plastic sheeting before applying any chemical treatment. Store all products in their original containers, away from children.

Step 1: Clear the Area and Remove Loose Debris

Applying a cleaning solution over leaves, grit, and loose moss is wasteful: the product binds to the debris rather than the surface. Start by removing all vehicles, bins, plant pots, and any other items from the driveway. Sweep the entire surface with a stiff-bristled brush, working from the highest point down toward the kerb or drainage channel. Use a leaf blower if you have one, particularly for getting debris out of the joints in block paving.

Once the dry sweep is done, use a stiff-bladed scraper to lift any thick deposits of moss or compacted organic growth. Bag the debris and dispose of it correctly rather than sweeping it into the road drain.

Pro Tip Dry debris removal is most effective on a dry day. Damp moss clings to surfaces and clogs brush bristles. If the surface is wet, allow it to dry before sweeping, or use the scraper first to break up the mat before brushing.

How to Remove Weeds from Block Paving and Other Surfaces

Weeds growing through the joints of block paving or cracking through concrete should be treated before any cleaning solution is applied. Use a stiff-bladed weeding tool or a pointed trowel to work along each joint and remove the root system. Simply pulling the visible growth leaves the root intact, and regrowth is rapid.

Once the physical weeds are removed, a targeted weed killer applied to the joints according to the product label will treat any remaining root material. Choose a product approved for use on hard surfaces and check that it is safe for use near drains. Allow the product to work for the time specified on the label before proceeding with cleaning.

For concrete driveways, weeds typically emerge through cracks. Remove them manually, then treat the crack with an appropriate sealant after cleaning to prevent regrowth. On tarmac surfaces, avoid any weed killer that contains solvents, as these can soften the binder in the tarmac.

Surface	Weed removal method	Notes
Block paving	Manual removal + jointing weed killer	Treat joints; re-sand after cleaning
Concrete	Manual removal + crack sealant	Seal cracks post-cleaning
Tarmac	Manual removal only	Avoid solvent-based weed killers
Resin-bound	Manual removal, no chemicals	Chemical weed killers can discolour resin

Best Driveway Cleaning Solutions for Every Surface Type

Choosing the wrong cleaning solution is where many DIY jobs go wrong. Surface-specific chemical compatibility matters: a product that works well on concrete can discolour block paving, and a bleach solution strong enough to clear algae from stone can soften the binder on tarmac.

Concrete Driveway

For general algae removal and organic growth, a diluted bleach solution (sodium hypochlorite at the concentration specified on the product label) applied with a pump sprayer and left to dwell for the recommended contact time is effective. Follow with manual scrubbing using a stiff-bristled brush, then rinse thoroughly.

For oil and grease stains, a dedicated degreaser formulated for porous surfaces is the correct choice. Apply, allow to dwell, scrub with a stiff-bristled brush, and rinse with hot water where possible.

Key Takeaway On concrete, the combination of a biocidal patio cleaner for organic growth and a separate degreaser for oil staining outperforms any single multi-purpose product.

Block Paving

Block paving requires a gentler approach than concrete. Many block paving units are coloured, and aggressive bleach solutions can cause fading or uneven discolouration. Choose a patio cleaner specifically labelled as safe for coloured block paving, and test it on a small, inconspicuous area first.

Apply the solution using a pump sprayer or watering can for controlled distribution. A nylon brush is preferable to a wire brush on block paving, as wire bristles can scratch the surface and dislodge jointing sand. After rinsing, check whether the jointing sand needs topping up: manual scrubbing removes some sand from the joints, and this should be replaced with kiln-dried jointing sand to prevent weed regrowth.

Tarmac and Resin-Bound Surfaces

Tarmac and resin-bound surfaces require the most careful product selection. Solvent-based cleaners and many strong chemical degreasers can dissolve the binder in tarmac or discolour resin aggregate. For tarmac, use a dedicated tarmac cleaner or a mild detergent solution and scrub gently with a stiff nylon brush. Avoid hot water, which can soften the surface.

Resin-bound surfaces are particularly sensitive. For organic growth, a diluted mildewcide or a product specifically approved for resin-bound surfaces is the safest option. Check with the surface manufacturer's guidance before applying any chemical treatment.

Step 2: Apply, Scrub, and Rinse Your Driveway

With the surface cleared and the correct cleaning solution selected, the cleaning process follows a consistent sequence: apply, dwell, scrub, rinse. Rushing any stage reduces the result.

Apply your chosen solution evenly using a pump sprayer or watering can. Work in sections rather than treating the entire driveway at once, so the product does not dry out before you can scrub it. The dwell time specified on the product label is the minimum time the active ingredient needs to break down organic growth or lift staining.

Scrubbing Technique for Algae, Lichen and Organic Growth

Manual scrubbing is more effective than most people expect, provided the technique is correct. For algae and general organic growth, use a long-handled stiff-bristled brush and work in overlapping circular motions rather than straight back-and-forth strokes. This lifts growth from the pores of the surface rather than simply pushing it across.

Lichen is harder to shift than algae because it physically bonds to the surface. A wire brush used carefully on concrete or natural stone can break the bond, but avoid wire brushes on block paving or resin. For persistent lichen, a second application of biocidal treatment after the first scrub, left to dwell again before a final scrub, is often necessary.

Rinse each section thoroughly with clean water from a garden hose before moving to the next.

Treating Oil, Grease and Rust Stains

Oil and grease stains require a different approach from organic growth. Apply a neat degreaser directly to the stain, cover it with an absorbent material such as cat litter or sand to help draw the oil to the surface, and leave it for the time specified on the product label. Remove the absorbent material, then scrub the area with a stiff-bristled brush and hot water.

Rust stains on concrete are caused by metal objects left on the surface. A purpose-made rust remover for concrete is the correct treatment. Apply according to the product label, scrub, and rinse. Do not use rust removers on block paving without confirming compatibility, as some formulations can etch or discolour the surface.

Step 3: Post-Cleaning Sealing and Maintenance to Prevent Regrowth

Cleaning the driveway is the first half of the job. Protecting it afterwards is where most DIY efforts fall short, and it is the reason moss and algae return within weeks rather than months.

Sealing a clean driveway creates a barrier that reduces the penetration of moisture, organic matter, and staining agents into the porous surface. For concrete and block paving, a penetrating sealant applied after the surface has dried completely is the most effective option. Apply sealant only to a fully dry surface. Applying over residual moisture traps it beneath the sealant, which can cause clouding or adhesion failure.

For ongoing maintenance, the most effective approach is a biocidal treatment applied annually in autumn, before the damp conditions of winter encourage moss and algae growth. Refresh Revive Exterior Cleaning offers maintenance visits specifically designed to prevent regrowth between full cleans, using surface-specific, low-pressure methods that protect planted areas and lawns alongside the driveway itself.

Common Mistakes to Avoid When Cleaning a Driveway Without Pressure Washing

Most failed DIY driveway cleaning jobs share the same handful of errors.

Applying cleaning solution to a dirty surface. Debris removal must come first. Applying a patio cleaner over leaves and loose moss wastes product and reduces contact with the actual surface.

Using the wrong product for the surface. A bleach solution suitable for concrete will discolour block paving. A solvent-based degreaser appropriate for concrete will damage tarmac.

Ignoring dwell time. The active ingredients in biocidal cleaners and degreasers need time to work. Scrubbing immediately after application significantly reduces effectiveness.

Scrubbing in one direction only. Straight back-and-forth scrubbing pushes organic growth along the surface rather than lifting it out of the pores. Circular or overlapping strokes are more effective.

Rinsing inadequately. Residual cleaning solution left on the surface can continue to react, potentially causing discolouration or attracting further organic growth. Rinse each section thoroughly with clean water.

Skipping post-cleaning sealing. Cleaning without sealing leaves the surface as porous as before. Moss, algae, and organic growth will return quickly without a protective barrier or a scheduled biocidal maintenance treatment.

Working in wet or windy conditions. Wet surfaces dilute the cleaning solution and reduce its effectiveness. Wind carries spray onto vehicles, glazing, and planted areas.

For anyone uncertain about the correct product for their specific surface, or dealing with persistent growth that manual scrubbing has not resolved, professional advice is worth seeking before committing to a product that could cause damage.

Frequently Asked Questions

What can I use instead of a pressure washer to clean a driveway?

A stiff-bristled brush or nylon brush combined with a purpose-made patio cleaner or degreaser is the most effective pressure washer alternative. Apply the cleaning solution on a dry day, work it in with firm circular scrubbing, then rinse thoroughly with a garden hose. For organic growth such as algae and lichen, a mildewcide-based treatment applied and left to dwell before scrubbing will give better results than water alone. Always follow the product label and wear gloves and safety goggles.

Is it safe to use washing-up liquid like Fairy to clean a patio or driveway?

Washing-up liquid can loosen light surface grime on a concrete driveway or patio when diluted in hot water, but it is not formulated to tackle algae, lichen, moss or deep staining. It also creates significant surface runoff that can harm plants and enter drains. For persistent organic growth or oil stains, a dedicated driveway cleaning solution or degreaser will be far more effective. Always check compatibility with your surface type before applying any cleaning agent.

How do I stop moss and algae coming back after cleaning my driveway?

Moss and algae regrowth is best prevented by applying a biocidal or mildewcide treatment after cleaning and allowing it to fully cure before rainfall. Sealing a concrete driveway or block paving after treatment closes the porous surface, making it harder for organic growth to take hold. Keeping joint sand topped up in block paving also reduces the gaps where weeds and moss establish. Setting a maintenance schedule, typically once or twice a year, keeps regrowth manageable before it becomes a deep-rooted problem.

How often should a driveway be cleaned to keep it in good condition?

Most driveways benefit from a thorough clean at least once a year, ideally in spring after winter grime has built up. Driveways in shaded or damp spots where algae and lichen thrive may need attention twice yearly. Debris removal, sweeping and clearing leaves, should happen more frequently throughout autumn and winter to prevent organic matter breaking down on the surface. A regular maintenance schedule prevents staining and organic growth from becoming deeply embedded, which makes each clean faster and less labour-intensive.
