What You'll Need To Clean Patio Slabs

Before we get into the cleaning methods let’s talk about the tools and materials you’ll need. Here are the essentials:

A bucket to mix your cleaning solution.
A hard-bristled brush to scrub the slabs.
Warm water to mix your cleaning solution.

You may also need:

Soap (liquid or powdered) for a gentle clean.
Bleach for a deeper clean especially for tough stains and plant life.
A pressure washer, a powerful tool for removing dirt and grime without scrubbing and suitable detergent if required.

Method 1: Cleaning with Soap and Water

If you don’t want to use harsh chemicals or don’t have a pressure washer, soap and water can be a gentle but effective way to clean your patio slabs. Here’s how to do it in six easy steps:

Step 1: Weed Removal

First clear any weeds. These unwanted visitors can grow between paving slabs so get them out as soon as you can. You can pull them out by hand or use a weed killer, just follow the product instructions, especially if you have pets or children.

Step 2: Prepare Your Cleaning Solution

Mix a mild soap with warm water in a bucket. A few squirts of dishwashing liquid or a sprinkle of powdered soap will do. Stir until you see foam on top.

Step 3: Apply the Mixture

Pour the soapy water over your patio slabs, start with the dirtiest areas. It’s always a good idea to test the solution on a small, inconspicuous area first to make sure it won’t damage your slabs.

Step 4: Scrub Away

Use your hard-bristled brush to scrub the slabs hard. The brush will get rid of dirt, moss and any remaining weeds. It’s a great workout and it’s effective!

Step 5: Rinse

After scrubbing rinse the area with clean water. This will wash away the soap and dirt that’s been lifted and reveal the clean slabs underneath.

Step 6: Don’t Forget the Joints

Make sure to clean the gaps between your slabs. Cleaning these joints will prevent weed growth and keep your patio structure intact.

Method 2: Using Bleach for a Deep Clean

Bleach can be a powerful cleaner for your patio slabs especially for tough stains, moss and algae. But use it with caution to avoid damaging your slabs or surrounding plant life. Here’s how:

Step 1: Mix Bleach with Water

Mix bleach with water 1:5 in a watering can for controlled application.

Step 2: Apply Evenly

Pour the bleach solution over your slabs, make sure to cover evenly. Be careful not to splash on plants or grass.

Step 3: Let It Sit, Then Scrub

Let the bleach work its magic for about 15 minutes then scrub the area with your brush. You’ll see a white foam forming, that’s the bleach reacting with the dirt and grime.

Step 4: Rinse Thoroughly

Finally rinse the area with plenty of clean water to remove all the bleach and loosened dirt.

Method 3: Pressure Washing

A pressure washer is a quick and easy way to clean your patio slabs without the need to scrub. Follow these steps for a hassle free clean:

Step 1: Clear Debris

Sweep away any loose debris like leaves or twigs from your patio.

Step 2: Set Up Your Washer

Attach your pressure washer to a water source and if applicable add detergent to the washer’s reservoir.

Step 3: Adjust and Clean

Set your washer to medium pressure and sweep across the patio, make sure to cover all areas evenly. The pressure washer will dislodge the dirt and it will be easy to rinse away.

Step 4: Finish Up

Once you’ve cleaned the whole area, detach your pressure washer and drain any remaining water to keep it in good condition.
