A backyard garden or a patio of your home is almost like a cover of a book. It’s the first thing most people notice when visiting you during the warm seasons of the year. However, it requires a lot of effort to maintain and there are many tasks that have to be taken care of.
You can probably agree that cleaning the pavement is the most tedious one. That’s why you should know how to clean garden slabs in the most effective way possible. If you’re interested in knowing different methods, this article will help you out!
Preparing Garden Slabs for Cleaning
Whether you will use a brush or a pressure washer for cleaning, you have to prepare the slabs beforehand. The preparation depends on how much effort you put into maintaining the slabs, but here are the general steps:
Step 1. Put Away Outdoor Furniture
When cleaning the garden slabs, furniture can make it difficult to reach certain spots, and you also risk damaging it if you don’t tidy it away before cleaning.
Step 2. Pull Out The Weeds
Make sure to remove the weeds between slabs. You can use any method of your choice, whether it’s pulling with hands or a weed puller. If you’re doing it by hand, grab the weeds by their roots so they won’t regrow as quickly.
You can also use a weed steamer or a weed killer spray. If you’re using a chemical mixture, make sure it doesn’t reach your garden plants, because it might kill them.
Step 3. Sweep Away Loose Debris
Finally, use a broom to get rid of any dirt, twigs, or pulled weeds. Getting rid of debris guarantees the best possible cleaning results.
Now that you’ve laid the groundwork, let’s get straight to the best methods of making your garden slabs look as good as new!
Cleaning Garden Slabs with a Brush
If you don’t own a pressure washer, you’ll have to clean the slabs manually using a brush.
Here’s a step-by-step guide to cleaning your garden slabs:
step 1. Get Your Equipment
You´ll need a brush, cleaning gloves, a bucket of water, and a cleaner of your choice (we will review different options down the line). We recommend getting a bigger brush with hard bristles.
The bigger the brush, the more area you will cover with each stroke, and the harder the bristles, the more effectively it will remove dirt. Also, make sure to wear cleaning gloves throughout the process to protect your skin.
step 2. Mix Your Cleaner with Warm Water in the Bucket
Warm water is more effective at soaking up the dirt, making it easier for you to scrub it away. If you’re using a detergent, carefully follow product instructions and mix it with enough water to avoid damaging your slabs or harming yourself.
step 3. Apply the Mixture Onto the Slabs and Start Brushing
Depending on the cleaner of your choice, you’ll either have to splash some of it onto a few slabs or you can pour it over the entire area all at once. Some cleaners require time to soak, while others don’t.
After applying your mixture, start scrubbing. To avoid damaging the jointing compound between the slabs, we recommend you brush diagonally.
step 4. Rinse the Slabs with Clean Water
When you’re done brushing the entire patio, rinse it off with clean water to get rid of any leftover cleaning mixture. If you’re happy with the way it looks after rinsing, that’s it, you’re done cleaning your garden slabs! But if it’s still dirty…
step 5. Repeat the Cleaning Process
If it’s your first time cleaning the slabs in a while, then it’s most likely that you’ll have to repeat the process a few times until they are completely clean.
What Cleaner to Use
There are many options of cleaners you can choose from, each with its own benefits. For example, bleach is best if your slabs are covered with moss and algae. You should mix 1 part of bleach with 5 parts of water to dilute it for safety.
Keep in mind that any runoff mixture will harm your plants, so be incredibly diligent when using a mixture with bleach. If you don’t want to risk it, you can use 1 part of white vinegar mixed with 1 part of water. Despite being non-toxic, it’s a powerful cleaning mixture.
Also, there are many cleaners specifically designed for patios and garden slabs. When using such a cleaner, you should always follow the instructions on the product label. Finally, if your garden slabs aren’t that dirty, you can simply use soapy water.
Cleaning Garden Slabs With a Pressure Washer
If you’re tired of kneeling over and brushing the slabs by hand, a pressure washer is a great option to consider. It’s arguably the most efficient method for cleaning garden slabs and can save you a lot of time and energy.
Here are the steps for using a pressure washer:
step 1. Fill up the Detergent Tank
Most pressure washers today feature detergent tanks that can hold liquid cleaners which get pressurized together with water. It results in more effective cleaning.
step 2. Connect Your Pressure Washer to a Water Supply
Make sure your garden hose is long enough for you to reach every garden slab you want to clean.
step 3. Start Cleaning
Most pressure washers in the U.S come with standardized nozzles that control the water pressure. You can control the water pressure with a nozzle at the end of the washer.
We recommend using either a yellow 15-degree or green 25-degree nozzle to avoid damaging the surface of your garden slabs. Additionally, keep your distance and don’t get too close to the slabs, because otherwise you also risk damaging your slabs.
step 4. Rinse the Slabs Clean Water
If your pressure washer utilizes a detergent tank, you want to rinse the slabs after cleaning to guarantee that no detergent is left on the surface.
