Best Pressure Washers for Block Paving in UK

Paving stones have to withstand a lot and therefore need regular care. We show you how to clean the paving stones properly and which products are suitable for this.

Paving stones have to withstand a lot. It’s not just rain and the weather in general that get to them. Weeds and leaves grow between the joints, objects fall on the paving stones and liquids leak out. To keep driveways, patios and paths looking well-kept, it is important that you clean them properly.

The degree to which paving stones become dirty depends on their location and type. On dark or textured surfaces, stains and dirt are less noticeable than on light and uniform ones. If the paving stones are in a sunny place, green deposits hardly spread. They attack stones in damp and windless places. Lichens, on the other hand, can occur anywhere.

Remove loose dirt from paving stones

Before using cleaners, sweep the coarse dirt off the stones.
Before using cleaners, sweep the coarse dirt off the stones.

Sweep your paving stones regularly to remove coarse dirt. This is also the first step before using other cleaning products. If you do not remove soil, leaves and plant debris first, a greasy mass will form together with the liquid.

Use a street broom or witch’s broom for cleaning. A plastic leaf broom is suitable for flowers and leaves. Battery-operated sweepers make it easier for you to work on large areas.

Cleaning joints

Moss and weeds often grow in the joints between stones. Joint brushes, weed scrapers or weed burners can help. Normally, you must not use weed killers on sealed surfaces. Failure to do so can be punished with a fine.

Removing coatings, stains and discolouration from paving stones

On paving stones with porous surfaces, liquids in particular should be handled with care: they quickly soak into the material and leave stains that are usually difficult to remove. Remove fresh stains such as red wine or grease splashes as quickly as possible.

If you clean your stones only rarely, green deposits will build up. For delicate materials, you will have to do it yourself. Scrub them with cleaning agents and a brush. On more robust stones, you can get rid of them with a pressure washer.

Cleaning paving stones with a pressure washer

Use a pressure washer to remove stubborn dirt from the paving stones. Test the stones in an inconspicuous place to see if they can withstand the high pressure.

Using a pressure washer is easy on the back and saves water. Biodegradable cleaning agents are available for heavy soiling and deposits. Some devices mix these directly into the water.

However, pressure washers also have a disadvantage. If you spray the joints with it, the dirt is spread over the entire surface. Even windows and house walls may get dirty and you will have to clean even more if you don’t use it properly. To avoid this, always direct the water jet away from the house wall. If necessary, lower the pressure a little.

Excessive water pressure can damage the surfaces of some stones, including concrete stones. Hard natural stones such as basalt, granite and quartzite cope much better. Before using a pressure washer, find out whether the stones can withstand the treatment. Even if you use a dirt cutter, caution and distance are important.

Tip: To prevent the device from spreading the dirt and damaging the stones, use a surface attachment. The circular nozzles loosen the dirt in a targeted and gentle manner. The attachment also has a splash guard. It prevents dirt particles from spreading in the area.

Cleaning concrete and natural stone paving stones

Well-kept paving stones make the garden look tidy. Clean them regularly and you will have less work.

If water and mechanical cleaning alone are not enough, you can use special products for natural stones and concrete. Use these only for the appropriate type of stone. If in doubt, test them first on an inconspicuous spot. This will tell you whether the material is discoloured or not.

The application differs depending on the type. Make sure to sweep the stones thoroughly before using cleaners. Most cleaners are applied directly to the paving stones. Then spread it with a brush and work it in well. Let it work and dry according to the manufacturer’s instructions. Finally, rinse with water. Sweep away some cleaners with a broom.

Note: Only use the cleaning agents if it is not expected to rain during the soaking time. Also, look for biodegradable products: when you rinse them off, they end up in your garden and in the sewage system. Some municipalities do not allow the use of certain cleaning agents. Check with the responsible authorities beforehand.

The right cleaner for the right dirt

Use solvent-based cleaners to treat paint stains, resin, alkali, grease and everyday stains. Cement residue and rust stains can be treated with acidic cleaners.

Cleaners containing acids and surfactants are unsuitable for natural stones such as granite, marble or sandstone. They attack the surface. For sandstone, it is better to use warm water and neutral soap or special natural stone cleaners or stone oil.

Only use special cleaners against lichen. High-pressure cleaners and green coat removers do not help here.

Tip: Don’t know what material your paving stones are made of? Put a little citric acid on the stone in an inconspicuous place. If white foam forms, it is usually lime. In this case, do not use acidic cleaning agents.
You can use a little citric acid to test whether the stones contain lime. If white foam forms on contact, acidic cleaning agents are not suitable for cleaning.

Cleaning concrete blocks with soda

Soda is an all-rounder in the household. You can also clean acid-sensitive paving stones with sodium carbonate. To do this, add about 100 grams of soda to 10 litres of hot water. Spread the mixture over the stones. Use a broom or rubber scraper. For your own safety, wear protective goggles. Leave the soda water to soak for five to six hours. Finally, wash the mixture off with clean water.

Cleaning sealed paving stones

Sealed or impregnated paving stones are easier to clean than untreated stones. The sealant prevents the surface from becoming dirty quickly. Use water and a little neutral detergent to wipe away dirt. Do not use a pressure washer, as it may damage the seal.
