As the weather starts to get warmer, many of us begin to spend more time outdoors, enjoying the sunshine and fresh air in our gardens and patios. However, after a long winter, our patio slabs can start to look dull, dirty, and even covered in algae and moss. This is where sodium hypochlorite, a common household bleach, comes in as a trusted and effective solution to clean and restore your patio slabs to their former glory.
Why Use Sodium Hypochlorite to Clean Patio Slabs?
Sodium hypochlorite, commonly known as bleach, is a powerful disinfectant and sanitizer that has been used for decades to clean and disinfect surfaces. When it comes to patio slabs, sodium hypochlorite is particularly effective due to its ability to break down and remove tough dirt, grime, and organic matter, including algae and moss. Additionally, sodium hypochlorite has a number of benefits that make it an ideal choice for cleaning patio slabs:
- Cost-effective: Sodium hypochlorite is a relatively inexpensive cleaning agent, making it a cost-effective solution for cleaning patio slabs.
- Easy to use: Sodium hypochlorite is widely available in most supermarkets and is easy to apply, making it a convenient cleaning solution for patio slabs.
Preparation is Key: Before You Start Cleaning
Before you start cleaning your patio slabs with sodium hypochlorite, it’s essential to prepare the area to ensure a safe and effective cleaning process.
Safety Precautions
When working with sodium hypochlorite, it’s crucial to take certain safety precautions to avoid accidents and injuries:
- Wear protective gear: Wear rubber gloves, safety glasses, and a face mask to protect yourself from skin and eye irritation, as well as inhalation of fumes.
- Keep away from children and pets: Sodium hypochlorite can be harmful to children and pets, so ensure they are kept away from the cleaning area.
Clear the Area
Clear the patio area of any loose debris, such as leaves, twigs, and furniture, to ensure a thorough cleaning process.
| Area | Action |
|---|---|
| Patio furniture | Move or cover with a tarp |
| Plant pots and plants | Move or cover with a tarp |
| Debris and loose material | Sweep or blow away |
The Cleaning Process: How to Clean Patio Slabs with Sodium Hypochlorite
Now that you’ve prepared the area, it’s time to start cleaning your patio slabs with sodium hypochlorite.
Step 1: Mix the Solution
In a bucket, mix 1 part sodium hypochlorite with 4 parts water. This solution is gentle enough for most patio slabs, but if you’re dealing with particularly tough stains or algae growth, you can increase the concentration of sodium hypochlorite.
Step 2: Apply the Solution
Using a long-handled brush or a mop, apply the sodium hypochlorite solution to the patio slabs, working in sections to avoid overlapping. Make sure to cover the entire surface, but avoid applying the solution to the joints between the slabs.
Step 3: Allow the Solution to Work
Allow the solution to sit on the patio slabs for 15-20 minutes to allow the sodium hypochlorite to break down and remove the dirt and grime.
Step 4: Rinse the Patio Slabs
Using a hose or a pressure washer, rinse the patio slabs thoroughly to remove the sodium hypochlorite solution and any remaining dirt and grime.
Step 5: Neutralize the Area
Once the patio slabs are clean, rinse the area with clean water to remove any remaining sodium hypochlorite residue.

What is Sodium Hypochlorite and How Does it Work?
Sodium hypochlorite is a strong disinfectant and sanitizer commonly used in cleaning and disinfecting surfaces, including patio slabs. It works by releasing oxygen free radicals, which destroy the cell membranes of microorganisms, effectively killing them. This makes it an effective solution for removing dirt, grime, and organic matter from patio slabs.
When using sodium hypochlorite to clean patio slabs, it’s essential to follow the instructions carefully and take necessary safety precautions to avoid accidents or damage to the slabs. It’s also important to note that sodium hypochlorite can cause discoloration or damage to certain types of patio slabs, so it’s crucial to test a small area first to ensure it’s safe to use.
Is Sodium Hypochlorite Safe to Use on My Patio Slabs?
The safety of using sodium hypochlorite on your patio slabs depends on the type of slabs you have. Sodium hypochlorite is generally safe to use on concrete, limestone, and granite slabs, but it can damage or discolor certain types of natural stone, such as marble, travertine, or bluestone. It’s also important to avoid using sodium hypochlorite on sealed or painted surfaces, as it can damage the sealant or paint.
Before using sodium hypochlorite, always test a small, inconspicuous area of the patio slab to ensure it won’t cause any damage. If you’re unsure about the type of slab you have or its safety with sodium hypochlorite, it’s best to consult a professional or choose a different cleaning solution.
How Do I Mix the Sodium Hypochlorite Solution?
To mix the sodium hypochlorite solution, follow the instructions on the label or product instructions. Typically, you’ll need to mix one part sodium hypochlorite with three to five parts water. Make sure to wear protective gloves, safety goggles, and a face mask when mixing the solution to avoid skin and eye irritation and inhalation of fumes.
It’s essential to mix the solution in a well-ventilated area, away from children and pets. Avoid mixing the solution in a small, enclosed space, as the fumes can become trapped and cause respiratory problems.
How Do I Apply the Sodium Hypochlorite Solution to My Patio Slabs?
To apply the sodium hypochlorite solution to your patio slabs, use a soft-bristled broom or a mop to spread the solution evenly across the surface. Make sure to work in small sections, about 10 square feet at a time, to avoid spreading the solution too thin. Use a generous amount of solution, but avoid over-saturating the slabs, as this can lead to excess water pooling on the surface.
Let the solution sit on the surface for 15 to 30 minutes to allow it to effectively kill microorganisms and break down dirt and grime. Avoid applying the solution in direct sunlight, as it can evaporate too quickly and reduce its effectiveness.
How Do I Rinse My Patio Slabs After Using Sodium Hypochlorite?
After applying the sodium hypochlorite solution and letting it sit for the recommended time, rinse the patio slabs thoroughly with clean water to remove any remaining solution and debris. Use a hose with a wide fan tip to disperse the water evenly and avoid using a high-pressure washer, as it can damage the slabs.
Make sure to rinse the slabs in the direction of the drainage to avoid water pooling on the surface. It’s also important to remove any remaining debris and dirt from the surface using a soft-bristled broom or a squeegee.
How Often Should I Clean My Patio Slabs with Sodium Hypochlorite?
The frequency of cleaning your patio slabs with sodium hypochlorite depends on the amount of foot traffic, exposure to the elements, and overall maintenance of the patio area. As a general rule, cleaning your patio slabs every 2 to 3 months can help maintain their appearance and prevent the buildup of dirt and grime.
However, if your patio is exposed to heavy foot traffic, pet accidents, or frequent debris, you may need to clean it more frequently. Regular cleaning can help prevent stubborn stains and maintain the overall cleanliness and appearance of your patio slabs.
Are There Any Alternative Cleaning Solutions I Can Use?
Yes, there are alternative cleaning solutions you can use to clean your patio slabs, depending on the type of slab and the level of cleaning required. For example, a mixture of baking soda and water can be effective for removing minor stains and dirt from patio slabs. Vinegar and water can also be used as a natural and environmentally friendly cleaning solution.
However, for more stubborn stains or heavy buildup, sodium hypochlorite may be the most effective solution. Always test a small area first to ensure the alternative cleaning solution you choose won’t damage the patio slabs.
