How to Clean Paving Stones


If you have interlocking pavers or other stones then you should know how to clean these paving stones to keep your patio area looking fresh and well maintained.

No matter what type of paving stones you have, be it slabs, concrete, or singles, your cleaning procedure is the same.

In most cases, a little hard work, a brush, and soapy water are all you need to scrub up your pathways and have them looking as good as new once more.

If you have more stubborn stains that need to be removed, or problems with weeds, algae, or just general dirt build-up, there are simple steps you can take to remove them.

Read on for tips on how to clean interlock stone.

How to Clean Paving Stones

Start by giving your paving stones a brush with a stiff bristle broom to remove any debris and dirt sitting on the surface of your stones. This step will also prevent any seeds from germinating, as they won’t have anything to take root in.

Brushing will also break off any small weeds that have started sprouting and prevent them from growing further.

General Cleaning

Cleaning paving slabs with a hose will remove dust and grime left behind after sweeping. Do this occasionally to keep interlocking stones looking fresh.

If your paving stones develop stains that can’t be removed with a quick spray of the hose, make a simple cleaning solution of dish soap and warm water. Use a sponge or soft brush to scrub the affected area gently and then rinse.

Tough Stains

If you have tough stains, first read your stone manufacturer’s instructions. Not all stones can tolerate an abrasive cleaning solution.

If your patio can tolerate slightly acidic cleaners, we suggest you use diluted vinegar. Spray the mixture onto the stains and leave it for a half-hour. Then scrub the area with the brush of your choice.

It is important to rinse after using this cleaning method, to prevent the vinegar from damaging your interlocking stones.

Most stones can tolerate a pressure washer cleaning. Just be sure you’re not removing a sealant. Keep the pressure washer on a low setting and set the nozzle to “fan” instead of “jet.” Another tip is to spray across joints instead of up and down. That way, you protect the stones and prevent them from breaking or flaking off.

On certain types of stone, you can use bleach to remove stains and algae.  Dilute the bleach first with equal parts of water. Apply the bleach on a small stained area and let it sit, as a test, for a few minutes.

The bleach should lighten the stain but could lighten it too much. Only apply the mixture to the rest of your interlocking if you like the result of the test area.  When you’re done, rinse the stones multiple times with clean water to remove any leftover bleach. Also, when bleaching, watch for surrounding plants, as bleach can kill them.

Cleaning pavers is easier if you keep up with general maintenance and address potential stains right away. Need to know more about how to clean paving stones? Or just need replacements? Reach out to the experts at Lane’s Landscaping Supplies.
