How to clean patio slabs with soapy water

It isn’t necessary to have a pressure washer or use bleach to clean your paved area. A hard-bristle brush can get the job done. It’ll be more time-consuming and tiring than cleaning patio slabs with a pressure washer, but in the end, you’ll have a clean patio area.

Here’s how to clean the patio area:

Needed materials:

  • A bucket
  • A hard-bristled brush
  • Warm water
  • Soap

Steps to follow:  

Step 1# Removing weeds

Weeds are so persistent that they manage to find their way out into your area no matter what you do. If you have found any weeds, you’ll have to remove them. How you will remove the weeds depends on how big the problem is. You can try either weeding by hand or even using a weed killer to uproot weeds among the jointing. In case you want to use a weed killer, be sure you read the manufacturer’s instructions, especially if you have kids or pets

Step 2# Making the cleaning solution

The usual way to clean your paved area requires a brush, a mild soap, like washing up liquid and warm water. Just be careful with the detergent you’re about to use. Not all products are suitable for all paving slab types. For instance, if you have concrete paving, avoid using products containing acid. Or cleaning products containing limestone or marble, you should avoid them despite the slab material. Mix a few drops of the detergent with warm water and stir the cleaning solution to dilute the soap.

Step 3# Start cleaning

After mixing soap and water, pour the soapy water onto your dirty slabs. It would be best to divide it into small areas for better cleaning. Just remember! Before cleaning, check your solution on a small inconspicuous spot to ensure that the cleaning mixture won’t damage your pavers.

Step 4# Rinsing

Once everything is clean, rinse your area with clean water. In case you notice any stubborn dirty spots, wait for a few hours, and then you can repeat the process. 

Step 5# Cleaning the grout joints

The grout joints are the part of the surface that needs to be cleaned as dirt and grime tend to build up. Sweep and remove the weeds of the joints regularly and fill any gaps wherever necessary.

  • Bleach
  • A watering can
  • Lukewarm and cold water

  2. Using a bristle brush, scrub the paved area to get rid of dust and stains.
  3. Then, sweep the slabs with the broom to remove any debris. 
  4. After sweeping, pour lukewarm water onto the surface to loosen algae and other weeds. 
  5. Next, pour the bleaching solution over the slabs with the watering pot and start brushing with the stiff brush
  6. Once you’ve finished brushing the whole area, let the bleach stay for 15 minutes.

How to clean patio slabs with a pressure washer

Pressure washing is probably the easiest way to clean your patio. However, you need to be rather careful. Power washing can damage even natural stones, concrete and stone paving. It would be better if you used a fan setting than a jet. 

Needed materials:

Steps to follow:

  1. After sweeping your area, connect your power washer hose to the water and turn the tap on. If your device allows it, add some detergent as well.
  2. If you use detergent, spray your surface and allow 5-10 minutes to get into all cracks and joints.
