Patios are one of the most used outdoor spaces in a home, especially during the warmer months. Over time, though, they naturally collect dirt, algae, moss, black spots, and general weather staining. When this happens, many homeowners start looking for a cleaning solution that brings their patio back to life.
Two of the most common methods are jet washing and soft washing. While both aim to clean hard outdoor surfaces, they work in very different ways and deliver very different results. At Diverse Cleaning, we help homeowners choose the right method for their patio based on the surface type, condition, and level of staining.
Understanding the difference between these two approaches can help you avoid damage, improve results, and extend the life of your outdoor surfaces.
What Is Jet Washing?
Jet washing, often called pressure washing, uses high-pressure water to remove dirt and debris from hard surfaces.
It works by forcing water at high speed onto the patio surface to break up and remove:
- Dirt build-up
- Mud and grime
- Loose algae
- Surface staining
This method can be very effective for certain hard-wearing surfaces, especially when the contamination is light to moderate.
However, because of the high pressure involved, it is not always suitable for every patio type.
What Is Soft Washing?
Soft washing is a low-pressure cleaning method that relies on specialist cleaning solutions rather than force.
Instead of blasting the surface, soft washing works by:
- Applying biodegradable cleaning agents
- Allowing time for the solution to break down organic growth
- Gently rinsing away residue at low pressure
This makes it particularly effective for removing:
- Algae
- Lichen
- Black spots
- Organic staining
Soft washing focuses on treating the root cause of the staining rather than just removing surface dirt.
Key Differences Between Jet Washing and Soft Washing
While both methods clean patios, they achieve results in very different ways.
| Feature | Jet Washing | Soft Washing |
|---|---|---|
| Water pressure | High | Low |
| Cleaning method | Force removal | Chemical breakdown |
| Best for | Hard dirt and loose debris | Organic growth and staining |
| Risk of damage | Higher on delicate surfaces | Very low |
| Long-term results | Shorter-lasting | Longer-lasting |
When Jet Washing Is the Right Choice
Jet washing can be suitable in certain situations, especially where surfaces are strong and heavily soiled.
It may be used for:
- Concrete patios
- Heavily compacted dirt
- Loose surface debris
- General maintenance cleaning
However, it should always be used carefully to avoid surface erosion or joint damage.
When Soft Washing Is the Better Option
Soft washing is often the preferred method for patios affected by organic growth.
It is especially effective when dealing with:
- Green algae
- Black spot lichen
- Slippery surfaces
- Long-term staining
Because it treats the growth at its source, soft washing can provide longer-lasting results compared to high-pressure cleaning alone.
Risks of Using Too Much Pressure
One of the most common mistakes homeowners make is assuming more pressure equals a better clean.
In reality, excessive pressure can cause:
- Joint sand removal
- Surface etching
- Tile or slab damage
- Uneven colouring
- Weakened pointing
Over time, this can actually make patios deteriorate faster, leading to more maintenance work later.
Combining Both Methods for Best Results
In some cases, the best approach is a combination of both jet washing and soft washing.
For example:
- Soft washing to treat algae and organic growth
- Jet washing to remove loosened dirt and residue
This blended approach can deliver a deep, long-lasting clean without unnecessary damage.
Why Professional Patio Cleaning Matters
Choosing the right method is not always straightforward. Different patio materials respond differently to pressure and cleaning solutions.
Professional cleaners assess:
- Surface type
- Level of staining
- Joint condition
- Previous cleaning history
- Environmental factors
This ensures the correct method is used for safe and effective results.
At Diverse Cleaning, we tailor each job to the surface in front of us, rather than relying on a one-size-fits-all approach.
Long-Term Maintenance Benefits
Regular patio cleaning helps to:
- Reduce slippery surfaces
- Prevent moss regrowth
- Maintain appearance
- Protect surface integrity
- Extend lifespan of materials
Many homeowners combine occasional deep cleans with lighter maintenance to keep their patios in good condition year-round.
Choosing the Right Method for Your Patio
If you are unsure whether jet washing or soft washing is best, it usually comes down to the condition of the surface.
Jet washing may suit newer, robust patios with loose dirt.
Soft washing is often better for older patios or those affected by algae and staining.
A professional assessment is the safest way to determine the correct method.
Conclusion
Jet washing and soft washing both have their place in patio maintenance, but they are not interchangeable. Jet washing relies on high-pressure water to remove dirt, while soft washing uses specialist treatments to target organic growth at its source.
At Diverse Cleaning, we use the most appropriate method for each patio to ensure a safe, effective, and long-lasting clean. By choosing the right approach, homeowners can protect their outdoor spaces, improve safety, and enjoy a patio that looks its best throughout the year.
