Natural sandstone can look fantastic when it is clean and well maintained, but it can also be one of the more difficult outdoor surfaces to clean correctly.

Over time, sandstone patios, paths, steps, pool surrounds and other outdoor areas can become covered in algae, moss, lichen, dirt and weathering. Black spotting can become particularly noticeable, while years of exposure to the British weather can leave the stone looking dull, dirty and completely different from how it originally looked.

With nearly 20 years of experience working with exterior surfaces, The Jet Wash Fella takes a different approach to sandstone.

Rather than simply turning up and blasting the surface with a pressure washer, I look at the condition of the stone first and choose a cleaning method that is appropriate for the surface.

The aim isn’t simply to make sandstone look clean.

The aim is to improve its appearance while taking care not to unnecessarily damage the natural stone.

SANDSTONE IS NOT JUST ANOTHER PATIO SURFACE

One of the biggest mistakes people can make when cleaning natural sandstone is treating it in exactly the same way as concrete or block paving.

Sandstone is a natural, porous material and different slabs can vary considerably in hardness, condition and weathering.

Some areas may be perfectly sound, while other sections may already be softer, weathered or affected by previous cleaning.

That is why I don’t believe there is one pressure setting or one cleaning method that is suitable for every sandstone patio.

The condition of the stone matters.

The type of contamination matters.

And the cleaning method matters.

COMMON PROBLEMS WITH NATURAL SANDSTONE

BLACK SPOTS AND LICHEN

Black spotting is one of the most common complaints I hear from customers with sandstone patios.

These dark marks can be extremely stubborn and can become embedded into the surface over time.

Specialist treatment can help break down the organic contamination before the stone is carefully cleaned.

However, I will always be honest about expectations. Some black spotting can be extremely established, and the final result depends on the condition and age of the sandstone.

GREEN ALGAE AND MOSS

Damp, shaded areas can quickly become green and slippery.

Moss and algae are particularly common around walls, fences, trees and areas that receive little direct sunlight.

Cleaning can remove the visible growth and dramatically improve the appearance of the surface.

BUILT-UP DIRT AND WEATHERING

Sandstone is porous, so dirt can become trapped within the surface rather than simply sitting on top.

Over many years this can make the stone look dull, dark and lifeless.

Careful treatment and cleaning can remove much of this accumulated contamination and reveal more of the natural colour beneath.

WEATHERED OR FADED SANDSTONE

Not every change in colour is dirt.

Natural sandstone can weather over many years, and exposure to sunlight, rain, frost and general use can change its appearance.

Professional cleaning can reveal the natural character and colour that is still present, but cleaning cannot reverse every form of natural ageing or weathering.

That is why I prefer to explain what is realistically achievable rather than promise to make every patio look brand new.

WHY EXCESSIVE PRESSURE CAN DAMAGE SANDSTONE

This is an important point that is often overlooked.

Natural sandstone can be softer than many other outdoor surfaces. If excessive pressure is used, the surface can potentially be damaged.

In some circumstances, aggressive cleaning can remove small pieces or layers from the stone and leave areas rough, sharp or uneven.

It can also expose weaknesses that were already present in older or weathered sandstone.

More pressure does not automatically mean a better clean.

The objective is to remove the contamination without unnecessarily removing the stone itself.

That is why I assess the surface and adjust the cleaning approach according to the condition of the sandstone.

MY APPROACH TO SANDSTONE RESTORATION

There isn’t a single process that suits every sandstone surface, but my approach generally begins with understanding what I am dealing with.

1. ASSESSING THE SANDSTONE

Before cleaning begins, I look at the condition of the slabs, the type of contamination, the joints and any areas that may already be damaged or weathered.

2. CLEARING THE SURFACE

Loose dirt, leaves, moss and other debris are removed so that the sandstone can be properly assessed and treated.

3. SPECIALIST SOFT-WASH TREATMENT

Where appropriate, I apply a suitable specialist treatment to help break down algae, organic growth, dirt and other contamination.

The treatment needs to be given enough time to work rather than simply being applied and immediately washed away.

4. CONTROLLED CLEANING

After the treatment has had time to work, the sandstone can be carefully cleaned using controlled pressure appropriate to the surface.

I don’t believe in simply turning the pressure up as high as possible.

5. RE-TREATING STUBBORN AREAS

Some areas may require additional treatment, particularly where black spotting, lichen or heavy organic growth has been established for a long time.

6. FINAL INSPECTION

Once the cleaning is complete, I inspect the surface to see how it has responded and whether any areas require further attention.

The final result depends on the condition of the sandstone, but the aim is always to leave the surface cleaner, safer and looking considerably better while preserving as much of the natural stone as possible.

WHAT CAN PROFESSIONAL SANDSTONE CLEANING IMPROVE?

Depending on the condition of the surface, professional cleaning can help improve:

• Algae and green growth
• Moss
• Lichen
• Surface dirt
• General grime
• Weather-related staining
• Some black spotting
• Slippery organic contamination
• Dull and dirty-looking sandstone
• The overall appearance of patios, paths and outdoor areas

It is important to understand that cleaning has limitations.

Deep staining, permanent discolouration, physical erosion and previous damage to the stone cannot necessarily be removed simply by cleaning.

CLEANING AND RESTORATION ARE NOT THE SAME THING

The word “restoration” can sometimes make people think a piece of sandstone can be returned to exactly how it looked when it was first installed.

Unfortunately, that isn’t always possible.

For me, sandstone restoration means looking at the overall condition of the surface and doing what can reasonably be done to improve it.

That could include:

• Specialist cleaning
• Organic growth removal
• Black spot treatment
• Careful pressure cleaning
• Re-sanding joints where appropriate
• Repointing
• Improving the overall appearance
• Discussing suitable protection or sealing

Sometimes the biggest improvement simply comes from revealing the natural colour of the stone that has been hidden beneath years of contamination.

NOT EVERY SANDSTONE PATIO CAN BE MADE TO LOOK “LIKE NEW”

I would rather be honest with a customer before starting a job than promise something that the stone cannot deliver.

If sandstone has been heavily weathered for decades, badly damaged by previous cleaning or naturally deteriorated, cleaning cannot undo that physical damage.

Likewise, some deep black staining may remain even after specialist treatment.

The final result depends on factors such as:

• The age of the sandstone
• The type of sandstone
• How porous the stone is
• Previous cleaning methods
• The severity of staining
• The amount of organic growth
• Weathering and exposure
• Existing damage

A good sandstone cleaning job is about achieving the best realistic result for the condition of the stone.

SANDSTONE PATIO RESTORATION

Sandstone patios are one of the most common surfaces I work on.

A patio that has become dark, green and heavily weathered can look completely different after professional cleaning.

The natural variations in the stone can become visible again, helping restore some of the character that made the sandstone attractive in the first place.

I particularly like seeing the natural colours come back through once the years of dirt and organic growth have been removed.

SANDSTONE PATHS, STEPS AND OUTDOOR AREAS

Sandstone isn’t limited to patios.

I also clean natural sandstone used for:

• Garden paths
• Steps
• Courtyards
• Garden seating areas
• Entrances
• Walkways
• Outdoor entertaining areas
• Pool surrounds

These areas can suffer from the same problems as patios, particularly algae and moss in damp or shaded locations.

NATURAL SANDSTONE SWIMMING POOL SURROUNDS

Pool surrounds require additional care because of their position around water and the importance of protecting the surrounding area during cleaning.

Natural sandstone can be used for pool coping, paving and surrounding areas, but it still needs to be cleaned according to the condition of the stone.

I take care around the pool itself and use appropriate cleaning and treatment methods to improve the appearance of the sandstone without unnecessarily attacking the surface.

SANDSTONE THAT HAS BEEN CLEANED INCORRECTLY

If someone has previously used excessive pressure on sandstone, the surface may show signs of damage.

You may notice:

• Rough patches
• Small areas of surface loss
• Uneven areas
• Sharp edges
• Changes in texture
• Areas that look different from surrounding slabs

Cleaning cannot always reverse this type of damage.

However, understanding what has happened is important before any further cleaning is attempted.

In some cases, continuing to use aggressive pressure could simply make the problem worse.

SHOULD SANDSTONE BE SEALED AFTER CLEANING?

Sealing isn’t automatically required for every sandstone surface.

Whether it is appropriate depends on the type and condition of the stone, how the area is used and what the customer wants to achieve.

A suitable sealer may provide additional protection in some situations, but it should be considered carefully rather than treated as an automatic final step.

I can discuss the options with you after assessing the sandstone.

HOW OFTEN SHOULD NATURAL SANDSTONE BE CLEANED?

There isn’t a fixed cleaning schedule that suits every property.

A sandstone patio surrounded by trees and shade may become dirty much faster than an open patio exposed to plenty of sunlight.

Factors include:

• Shade
• Trees and vegetation
• Moisture
• Drainage
• Foot traffic
• Weather
• General maintenance

Some customers simply want their sandstone cleaned when it starts looking tired, while others prefer regular maintenance to keep organic growth under control.

BEFORE AND AFTER: LET THE STONE SPEAK FOR ITSELF

One of the best ways to understand what professional sandstone cleaning can achieve is to look at genuine before-and-after photographs.

The biggest difference isn’t always about making the stone dramatically brighter.

Often it is about removing the layer of dirt, algae, moss and grime that has been hiding the natural colour and character of the sandstone.

The stone itself should remain the feature.

WHY CHOOSE THE JET WASH FELLA FOR SANDSTONE?

I’ve been working with exterior cleaning and pressure washing for nearly 20 years.

That experience has taught me that cleaning isn’t simply about having a powerful machine.

It’s about understanding the surface in front of you.

I don’t approach sandstone with the attitude that every patio should be cleaned in exactly the same way.

I look at the stone, the condition, the contamination and what the customer wants to achieve before deciding how best to approach the job.

My aim is simple:

Get the best possible result without unnecessarily damaging the surface.

FREQUENTLY ASKED QUESTIONS ABOUT SANDSTONE RESTORATION

1. Can black spots be removed from sandstone?

Black spotting can often be significantly improved with appropriate treatment and cleaning, but results vary. Some established staining may remain depending on the condition and age of the stone.

2. Can you pressure wash natural sandstone?

Yes, but the pressure and cleaning method need to be appropriate for the particular sandstone. Excessive pressure can damage softer or weathered stone.

3. Is sandstone easy to damage?

Sandstone can be more vulnerable to aggressive cleaning than harder paving materials. The condition of the stone is particularly important when deciding how it should be cleaned.

4. Can you remove moss and algae from sandstone?

Yes. Specialist treatment and careful cleaning can remove moss, algae and other organic growth from many sandstone surfaces.

5. Can you make old sandstone look new again?

Cleaning can make a significant difference, but it cannot reverse every form of natural weathering, erosion or previous damage. I prefer to give realistic expectations before starting the work.

6. Do you use a rotary cleaner on sandstone?

I generally avoid using rotary surface cleaners on delicate sandstone. The cleaning method needs to be selected according to the condition of the stone.

7. Can damaged sandstone be repaired?

Some issues can be improved through cleaning, repointing or other remedial work, but physical damage to the stone itself cannot always be reversed.

8. Should sandstone be sealed after cleaning?

Not necessarily. Sealing depends on the type and condition of the sandstone and how the area is used. I can discuss whether it is appropriate for your particular surface.

9. Can you clean sandstone around a swimming pool?

Yes. Pool surrounds require additional care because of the nearby water, but natural sandstone pool surrounds can be professionally cleaned using an appropriate approach.

10. How long does sandstone cleaning take?

The time required depends on the size and condition of the area, how heavily contaminated it is and whether additional treatment or restoration work is required.
