Exterior spring cleaning
After a long winter, it’s no surprise that outdoor areas start to look tired.
Patios lose their colour, driveways become stained, and green algae quietly takes hold on walls and paths.
It happens gradually, so you often don’t notice it—until everything feels dull and neglected.
The good news is that a thorough exterior clean can completely transform your space in a matter of hours.
With the right approach, you’re not just improving appearance—you’re protecting surfaces, preventing damage, and making future maintenance far easier.
Begin with a deep clean
If there’s one step that delivers instant results, it’s pressure washing.
Over the colder months, dirt, moss, and grime build up layer by layer.
A reliable pressure washer cuts through this quickly, revealing the original finish underneath.
For most homes, electric machines such as the Karcher K4 Classic Pressure Washer or Karcher K5 Classic High Pressure Washer are more than capable of handling patios, decking, and general outdoor cleaning.
Where the job is bigger or more demanding, petrol-powered options like the Proplus 7HP Petrol Pressure Washer (180 Bar) or the 13HP Petrol Pressure Washer offer serious power and independence from mains electricity.
They’re particularly useful for large driveways, yards, or heavily soiled areas.
For those looking for a premium domestic solution, the Karcher K7 Premium Smart Control Flex High-Pressure Washer or Karcher K7 Comfort Premium Pressure Washer provide excellent pressure and control, making light work of larger exterior spaces.
The right tools matter
A common mistake is relying on the washer alone.
In reality, the right accessories can completely change the outcome.
Using a surface cleaner such as the Karcher T5 Surface Cleaner allows you to clean patios and driveways evenly, avoiding the striping effect that often comes from a standard lance.
It also speeds up the job significantly, which makes a real difference on larger areas.
For higher or awkward spots, the Karcher TLA4 Telescopic Spray Lance with Hinge gives you safe reach without ladders.
Walls, gutters, and facades become much easier to manage, and you can clean thoroughly without overreaching.
For gutters in particular, the Gutter Brush 4 metres x 100mm makes clearing leaves and debris simple, safe, and far less time-consuming.
Adding the Karcher FJ6 Foam Nozzle into the mix helps when using detergents, as it allows the cleaning solution to cling to surfaces rather than running off too quickly.
Paired with the Karcher Foam 3 in 1 Cleaner, this creates a deeper, more effective clean—especially on heavily soiled areas.

The key to long-lasting results
Water pressure alone will remove surface dirt, but it won’t always solve the underlying problem.
For everyday cleaning, the Karcher Universal Cleaner (1 litre) helps break down general grime and traffic film.
When it comes to patios and paving, the Karcher Stone Cleaner (3-in-1) works deeper into the surface, restoring colour and lifting ingrained dirt.
More stubborn issues need targeted treatment.
Oil stains can be effectively tackled using ProtectiT Oil Off, while white salt deposits on paving are best removed with ProtectiT Efflorescence Remover.
Algae, mould, and fungi are particularly persistent.
Simply washing them away won’t stop them returning.
A proper treatment such as Actiwash Pro Biocide or Actiwash Domestic Biocide tackles the root of the problem, helping to prevent regrowth and keeping surfaces cleaner for longer.
Details matter
Even with the best equipment, some areas need a more hands-on approach.
Edges, joints, and tight corners tend to trap dirt and moss.
Taking the time to go over these sections with a Patio Wire Brush & Scraper ensures a more complete finish and avoids that “half-cleaned” look.
A 14" Yard Brush with Clamp is ideal for clearing debris before and after washing, while a Heavy Duty Yarn Mop & Wooden Handle can be useful for applying treatments or rinsing surfaces where needed.
These smaller tools might seem simple, but they make a noticeable difference to the final result.
High & hard-to-reach spots
It’s easy to focus on the ground, but vertical surfaces often carry just as much dirt.
Walls, render, and exterior finishes can become stained over time, especially in damp or shaded areas.
With the help of the Karcher TLA4 Telescopic Spray Lance, these can be cleaned safely from the ground, restoring brightness and removing green build-up.
For tougher dirt or general refresh, applying ProtectiT Surface Reviver 5L – High-Performance Cleaner ensures a deep, effective clean that brings surfaces back to life.
For smaller or more awkward jobs, the Worx 20V WG620E.2 Hydroshot Cordless Power Washer offers flexibility where a traditional setup isn’t practical.
It’s ideal for quick clean-ups, garden furniture, or areas without easy access to power or water.
Protecting your work
Once everything is clean, it’s worth taking one extra step.
Applying a protective treatment such as ProtectiT SEAL-iT helps guard against future staining, slows down algae growth, and makes ongoing cleaning much easier.
It essentially locks in the results you’ve just achieved, meaning you won’t have to work as hard next time.
A smarter way to maintain your home
Exterior cleaning isn’t just about appearances—it’s about staying ahead of problems before they take hold.
Regular maintenance prevents surfaces from deteriorating and reduces the need for more intensive work later on.
By combining the right equipment with the correct treatments and accessories, you can achieve a professional finish without unnecessary effort.
More importantly, you create an outdoor space that feels fresh, safe, and ready to enjoy again.
