Keeping your paving slabs clean is one of the simplest ways to restore the beauty of your outdoor spaces and protect them from long-term wear.
Over time, natural growths like moss and algae can dull the appearance of patios, driveways and garden paths, making them slippery underfoot and unsightly to look at.
Knowing how to clean paving slabs properly ensures your surfaces not only look their best, but also remain safe, hygienic and well maintained throughout the year.
At Jeyes Fluid, we’ve been helping homeowners care for their outdoor spaces since 1877. With over 145 years of expertise in outdoor hygiene, we understand what it takes to remove stubborn grime and restore paving to a like-new finish.
In this step-by-step guide, our cleaning experts share the safest and most effective methods for tackling everyday dirt, seasonal build-up and deep-rooted stains - using trusted Jeyes Fluid outdoor cleaning solutions that deliver powerful results with every application.
Why Cleaning Your Paving Slabs Matters
Paving slabs are constantly exposed to the elements - from rainfall and frost to fallen leaves, mud and garden debris.
Over time, this exposure allows dirt, moss and algae to build up across the surface. Not only does this make your patio or driveway look tired and discoloured, but it can also create a slippery layer that poses a safety risk, particularly during wet or cold weather.
Regular cleaning is about much more than just keeping things looking tidy. It helps protect the integrity of your paving, preventing organic matter and grime from settling into the stone or concrete where it can cause staining and deterioration.
Left untreated, this build-up can also encourage weeds to take root between slabs, making maintenance harder in the long run.
By taking the time to clean your paving slabs properly, you’ll not only improve the appearance of your outdoor space, but also extend the life of your surfaces.
Our heritage and expertise make us the brand homeowners continue to trust for powerful, reliable results that stand the test of time. For more on our history and heritage, visit our About Us page.

How to Clean Paving Slabs – Step by Step
Cleaning paving slabs properly doesn’t need to be difficult - it just requires the right approach and a trusted cleaner. Follow these steps for safe, effective results that restore your outdoor surfaces to their best condition.
Step 1 – Clear and Prepare the Area
Begin by removing any furniture, plant pots, or garden accessories from your patio or path. Sweep away loose dirt, leaves and debris using a stiff outdoor brush. Clearing the surface first will make cleaning more effective and prevent dirt from spreading as you wash.
If you notice weeds or moss growing between the slabs, use a scraper or edging tool to lift them out before applying your cleaner. This ensures the solution can penetrate deeply into the paving surface for a more thorough clean.
Step 2 – Apply Your Chosen Cleaner
Next, prepare your cleaning solution according to the product instructions. For general disinfection and algae removal, Jeyes Fluid Original Outdoor Disinfectant 5L can be diluted and applied evenly over the surface using a watering can or garden sprayer.
For heavier build-up or stubborn grime, Jeyes 4-in-1 Patio & Decking Cleaner 4L offers powerful four-in-one action - cleaning, disinfecting, removing algae and reviving the natural colour of your slabs.
Apply the cleaner generously across the entire area and leave it to work for the time stated on the label. This contact time allows the active ingredients to break down dirt and organic growth for easier removal.
Step 3 – Scrub and Rinse Thoroughly
Once the solution has had time to act, scrub the paving with a stiff brush or broom to lift away loosened grime and stains. Work in small sections to ensure even cleaning, focusing extra attention on any areas with visible discolouration.
Rinse thoroughly using a garden hose to wash away all residue. This is important for preventing streaks and ensuring the surface is safe for use once dry. Avoid rinsing large amounts of cleaning solution into drains or lawns - instead, direct rinse water into gravel or paved areas where possible.
Step 4 – Treat Stubborn Stains and Algae
For patches of black spot, lichen, or heavy algae growth, a repeat treatment may be needed. Apply a second coat of cleaner to the affected areas, scrub again and rinse well.
The Jeyes Driveway & Masonry Cleaner 5L is particularly effective here, cutting through tough deposits and restoring the natural finish of stone and concrete.
For ongoing prevention, consider applying your chosen cleaner periodically through the year to stop algae returning and to maintain a fresh, clean appearance.
Step 5 – Allow to Dry and Inspect
Finally, allow the surface to dry completely before replacing furniture or plant pots. Once dry, check the paving for any missed spots and touch up if necessary.
Regular maintenance - a quick sweep or rinse every few weeks - will help keep your paving in excellent condition between deep cleans.
With these steps complete, your paving slabs should look clean, refreshed and ready to enjoy once more.

How to Keep Paving Slabs Cleaner for Longer
Once your paving slabs are clean and restored, a few simple maintenance habits will help you keep them that way for longer.
Regular attention prevents dirt, moss and algae from returning - saving you time and effort in the future while preserving the beauty and safety of your outdoor spaces.
1. Sweep Regularly
A quick weekly sweep can make a big difference. Removing fallen leaves, soil and debris stops organic matter from breaking down and feeding algae growth.
It also prevents stains from forming, especially in shaded or damp areas.
2. Rinse After Wet Weather
After heavy rain or during the wetter months, give your paving a light rinse with a garden hose.
This washes away surface dirt before it settles and helps reduce the likelihood of moss or algae forming.
3. Apply a Protective Sealer
For lasting protection, consider sealing your paving after cleaning. A quality sealer acts as a barrier against water, grime and frost damage, helping to keep your paving looking newer for longer.
We recommend Jeyes Masonry & Driveway Sealer 5L - ideal for protecting stone, concrete and brick surfaces from the elements.
4. Schedule Seasonal Deep Cleans
Even with regular upkeep, a deeper clean once or twice a year (typically in spring and autumn) will keep your outdoor areas fresh and hygienic.
Using trusted outdoor cleaning solutions from Jeyes Fluid ensures long-lasting results and helps prevent stubborn build-up from taking hold.

Common Mistakes to Avoid!
Cleaning your paving slabs might seem straightforward, but small missteps can lead to damage or less effective results.
Avoiding these common mistakes will help you protect your surfaces and get the most from your outdoor cleaning routine.
1. Using Bleach or Harsh Chemicals
Household bleach and acidic cleaners can discolour or weaken paving materials, especially natural stone.
They can also harm plants and surrounding soil. Instead, always use purpose-made outdoor cleaning products like Jeyes Fluid Original Outdoor Disinfectant 5L - formulated to clean powerfully yet safely across patios, paths and driveways.
2. Failing to Rinse Thoroughly
Leaving cleaner or debris on the surface after scrubbing can lead to streaking or residue once dry.
Always rinse thoroughly with clean water to ensure a smooth, even finish and a safe, slip-free surface.
3. Using the Wrong Tools
Metal brushes or wire scrapers can scratch and damage paving surfaces, making them more prone to moss and dirt build-up later.
Opt for a stiff-bristled outdoor brush instead - strong enough to clean effectively without harming the stone.
4. Skipping Protective Gear
Outdoor cleaners are designed for powerful performance, so always wear gloves and avoid contact with eyes and skin.
Taking these small precautions keeps the cleaning process safe and straightforward.
5. Ignoring Manufacturer Instructions
Each cleaner is formulated differently, so following the dilution ratios and contact times on the label ensures both safety and effectiveness.
Jeyes Fluid products are developed to work efficiently when used exactly as directed - giving you professional results with peace of mind.
By avoiding these pitfalls, you’ll keep your paving looking its best while protecting your investment for years to come.

Frequently Asked Questions
Can I use bleach to clean paving slabs?
It’s best to avoid bleach. While it might remove surface dirt, bleach can discolour stone and concrete over time, damage nearby plants and harm surrounding soil.
Instead, use a dedicated outdoor cleaning solution such as Jeyes Fluid Original Outdoor Disinfectant 5L - formulated to clean effectively, disinfect safely and protect your outdoor surfaces without harsh side effects.
Is Jeyes Fluid safe for all types of paving?
Yes - when diluted and applied as directed, Jeyes Fluid products are suitable for most paving materials, including concrete, brick and stone.
However, for natural or delicate stone, it’s always best to test on a small, inconspicuous area first. Each formula is designed to deliver powerful cleaning performance while maintaining the integrity of the surface.
How often should I clean my paving slabs?
For best results, aim to give your paving a thorough clean at least twice a year.
This keeps algae, moss and dirt under control and prevents long-term discolouration. In between deep cleans, a light sweep or rinse will help maintain a fresh, tidy appearance.
Can I pressure wash after using Jeyes Fluid?
Absolutely. Once the cleaning solution has been left to work and thoroughly rinsed off, a pressure washer can be used to enhance results and remove any remaining residue. Combining both methods gives your paving slabs a professional-quality finish that lasts.
