Benefits of Regularly Cleaning Limestone Patio Slabs
Limestone has a stunning natural texture and soft, earthy tones that bring a clean, classic look to outdoor spaces. But like any natural stone, limestone needs consistent care to keep it looking its best.
Regular cleaning goes beyond keeping up appearances, too. It’s about preserving the surface, protecting your investment, and maintaining a safe, enjoyable space for day-to-day use.
Limestone is far more porous than porcelain or composite options, which means it absorbs water, traps dirt more easily, and is prone to algae or lichen growth if left unchecked. Even fallen leaves, rain runoff, or a BBQ left too long in one spot can leave marks that quickly take hold.
A consistent routine for cleaning limestone patio slabs keeps this buildup at bay. Getting in the habit of tidying up your patio reduces the risk of permanent staining and discolouration, helping to preserve the original tone of the stone and prevents dullness that can set in over time.
You won’t have to stress as much about slippery surfaces when you keep moss and algae from taking hold on your patio either, particularly in shaded or damp areas. So, let’s get into how to clean limestone patio slabs below.
How to Clean Limestone Patio Slabs: Step-by-Step Guide
Cleaning limestone patio slabs is fairly simple and straightforward, and it can make a world of difference in how you enjoy your outdoor space. But, the last thing you want is to cause more harm than good, or work harder than necessary.
That’s why we’ve put together this detailed, step-by-step guide on how to clean limestone patio slabs. Let’s start with what you’ll need to clean your patio safely and effectively.
What You’ll Need Before You Start
It’s easy to think you can just utilize a homemade patio cleaner, be it bleach or maybe even apple cider vinegar. However, these DIY solutions will either fall short, cause more harm than good, or potentially both!
Don’t take any chances. Stick with the best patio cleaner in the UK, right here at Jennychem. We have a full lineup of patio and driveway cleaners you can count on, but you’ll probably find our alkaline patio and driveway cleaner to be the best choice.
Acid-based cleaners can be too aggressive for limestone. In contrast, this alkaline cleaner works its way deep into the stone’s pores to bring impurities to the surface where they can easily be removed. It works fast, and it’s really easy to use. Here’s what else you’ll need:
- A stiff but non-abrasive brush (natural or plastic bristles)
- A watering can or low-pressure sprayer
- A hose with a spray nozzle (avoid high-pressure washers for now)
- A bucket of clean water
- Microfibre cloths or old towels for drying
Make sure you have all this on hand, ready to go. In the meantime, here’s how to clean limestone patio slabs the smart way.
Step 1: Clear Loose Debris and Dry Brush the Surface
The first thing you need to do is remove any furniture, plant pots, or any loose items from the area. Use a broom or brush to sweep away leaves, soil, and general debris.
Then, dry brush the surface with your stiff-bristle brush to loosen any dried-on dirt or surface grime. This will go a long way in protecting the limestone’s integrity, preventing you from grinding grit into the stone later on.
Step 2: Prepare and Apply the Right Cleaner
Mix your pH-neutral cleaner according to the manufacturer’s instructions. Pour or spray it evenly across a small, manageable section of the patio. Work in the shade if possible to prevent the cleaner from drying too quickly - you might need to be strategic about when you clean the patio.
The best part of knowing how to use patio cleaner is you can let it do all the heavy lifting. Sit back and relax for 10-15 minutes while the active ingredients work their magic to lift that deep-seated grime for easier removal in the next step.
Step 3: Agitate With a Soft Brush, Never Abrasive Tools
Gently scrub the treated area using your soft-bristled brush. Move in circular motion to lift dirt from the textured surface without scuffing the limestone. Pay particular attention to grout lines or textured areas where debris tends to accumulate.
Just make sure you avoid wire brushes, steel wool, or anything abrasive. These tools can scratch and permanently damage the surface. Let the cleaner do the aggressive stain lifting, you’re just giving it a little extra help at the end.
Step 4: Rinse Away All Residue Thoroughly
Rinse the area thoroughly with clean water when you’re satisfied with how much scrubbing you’ve done. A hose with a spray nozzle works well for this. The goal is to flush away all soap residue, loosened dirt, and contaminants.
Residues left behind can create streaks or attract fresh grime. So, make sure you are diligent in rinsing in sections as you go, rather than waiting until the very end. This prevents any cleaner from drying on the stone.
Step 5: Let It Dry and Inspect for Missed Spots
Allow the cleaned area to dry naturally. Avoid walking on the patio while it dries to prevent tracking dirt across your freshly cleaned surface.
Then, you can inspect your work and take note of any missed patches or stubborn stains. There are separate tips on how to clean limestone patio slabs when you’re dealing with these issues.
What About Algae, Rust, or Oil Stains?
Whether you’re wondering how to clean green off patio or how to remove black spots from patio slabs, these tough stains call for a more targeted treatment:
- Algae or Lichen: Use a specialised algae remover that’s safe for natural stone. Apply as directed and allow adequate dwell time.
- Rust Stains: Choose a rust remover specifically labelled for use on limestone. Many general rust products are too harsh.
- Oil Stains: Blot the stain with a paper towel. Apply a degreaser or poultice product made for porous stone. Repeat if necessary.
Even if you feel pretty confident your chosen patio cleaner is safe for stain removal, it’s worth spot testing the product in an inconspicuous area first.
Can You Pressure Wash Limestone Patio Slabs?
We get customers asking us all the time for tips on how to pressure wash a patio. After all, we carry the full lineup from Kranzle power washer. But, we generally recommend you don’t pressure wash limestone.
It’s tempting since you can avoid the manual scrubbing side of how to clean limestone patio slabs, but this can force water into the stone’s pores, weakening it over time and causing surface damage.
If you must use a pressure washer - maybe because you don’t have a garden hose that reaches long enough - you should use the wide-angle fan tip on the lowest pressure setting. Keep the nozzle at least 30-40 cm from the surface and test on a small area first.
Should You Seal Your Limestone Patio Afterwards?
Cleaning limestone patio slabs is fairly easy, and something you should do regularly. But why work harder when you could work smarter? Sealing your patio can protect both the appearance and structure of the stone.
Remember, limestone’s porous nature invites water, dirt, and stains in - which leads to discolouration, algae growth, or even frost damage in colder climates. Here’s when you SHOULD seal your patio:
- You live in a damp or shaded area. Constant moisture encourages algae and mould.
- The patio is near trees or plants. Organic matter can stain and settle into the pores.
- You want easier cleaning. A sealed surface doesn’t grip dirt and can often be cleaned with just water.
- You want to preserve colour. Some sealants help retain that pale, chalky appearance and resist UV fading.
So, what should you look for in a sealant and how do you apply it properly?
Choosing the Right Sealant for Limestone
Not all sealants are suitable for limestone, just like not all cleaners are effective. You’ll want to choose a breathable, penetrating sealant designed for natural stone - something that soaks into the surface without forming a glossy or slippery film.
Avoid solvent-heavy products unless they’re specifically made for limestone, as these can sometimes cause patchiness or even discolouration.
Also consider whether you want a natural finish (which keeps the stone looking untreated) or a colour-enhancing sealant, which will deepen the tone slightly and bring out more contrast in the stone.
How Often Should You Reseal a Limestone Patio?
Most high-quality sealants will last between 2-5 years, depending on the weather conditions and usage. You’ll know it’s time to reseal when:
- Water no longer beads on the surface but soaks in
- Stains become harder to remove
- Algae starts forming more quickly after cleaning
Always make sure the patio is fully clean and completely dry before resealing - ideally after a stretch of dry weather. Otherwise it may not bond properly.
