Pressure washing is one of the most effective ways to clean your pavers. However, if not done properly it cause permanent damage and deterioration to the surface. Excessive water pressure may remove dirt and grime build-up but it can also eat away at the material.
You can use a pressure washer on your patio pavers if you want to clean stubborn stains or mildew from them. However, be very careful when doing this! Use a gentle spray and avoid letting the water run down the sides of your pavers, especially if they're set in the sand rather than mortar.
Usually, hosing them down once a month is sufficient. Use soap and water, if the pavers are still dirty after sweeping and water hosing, make a solution of soap and water. You can use dish soap, laundry detergent, or any type of general-purpose cleaner. Never use bleach on your pavers, as it can damage the surface.
Can you power wash pavers? Power washing (also known as pressure washing) is also a very effective method by which you can remove dust deposits and various stains from your pavers. Just make sure that the water jet is not directed directly at the joints between the paving stones.
The pressure washer in combination with a dirt cutter is an excellent option. This removes not only weeds and moss from the surface, but also from indentations. Keeping up with this type of cleaning means that there is less time for weeds to grow. It also helps to maintain the beauty of the paving stones' surface.
Pressure Washing: Start by having the whole area pressure washed before sealing pavers. Grime and dirt can inhibit the paver sealant from penetrating. As a result, the paver stones may start pitting, and discoloration can happen. You are also likely to seal dirt beneath the coating.
If you're going the DIY route, all you need to do is grab a large bucket and combine warm water with a mild degreasing dish detergent. Stir the solution well, then evenly distribute the solution over the pavers. Do not use acid-based cleaners as this can damage the seal.

3) USE A CLEANER FIRST
I used a bleach-free pressure washer concentrate and sprayed it over each section to help loosen the grime before going at it with a higher pressure nozzle. It didn't take long to apply and helps get those stubborn mildew stains out.
The acetic acid in vinegar is a little stronger than acid rain, so exposing your pavers to this substance can lead to bleaching, corrosion and the loss of protective sealant.
If the pavers are wet due to a pressure wash, allow them at least 24 hours to air dry. They may need a reseal after a deep clean, which is crucial to wash away residue. Excessive moisture from intense heat can also hinder the sealing process.
Yes, a pressure washer can damage a patio by degrading the surface of the slabs. This in turn can allow more dirt to work its way into marks and pits in the stone in the future. When you clean a patio with a pressure washer, it is best not to use a super-high pressure and instead go more gently.
Power or pressure washing will clear out the weeds from a Cobblelock block paving driveway or path, so they are gone ... but only for for a short time. But although the surface looks good when we leave a customer's property, neither softwashing nor power or pressure washing actually kills the weeds.
The downside to using pressure washers is that they tend to cause damage to surfaces that are too delicate. In addition, the high pressure of the water spray can cause damage to surfaces you don't intend for it to reach, such as brick or stone surfaces.
Negatives – Using a pressure washer to clean your home may not be all that it is cracked up to be. The pressure can blast through wood, asphalt and even concrete if close enough. So, you're forcing water behind the siding which could cause problems within your walls and you wouldn't even know until it's too late.
The main difference is that power washing uses highly pressurized steam to do the cleaning while pressure washing just uses unheated tap water, without the help of a heating element.
Understandably, some will think this indicates the blocks are in some way faulty, sub-standard or iffy, but that's not necessarily the case. The cause for this visible difference in appearance is most commonly* a variation in the concrete used to make the blocks.
The good news is that pavers are known for their durability and lifespan. Made of clay, concrete, natural stone, or even porcelain, pavers can last 20-25 years without any major repairs with proper care and maintenance. If they are properly cared for and sealed, concrete pavers can last upwards of 50 years.
For the average homeowner who wants to wash their car, clear dirt off the siding of their house and dig out all the gunk in between 30-year-old pavers, the Sun Joe SPX 3000 XT1 is the best pressure washer for the job.
Wash patio slabs with white vinegar
This eco-friendly solution is made up of equal parts vinegar and water, which is then left to soak into the patio to correct any discolouration and also remove tough marks. You should first move all plants and furniture out of the way, then sweep the area to remove any moss.
If you are prepared to use chemicals to remove algae, lichen and moss from your pavers, it is important that you use plastic sheeting to protect other plants in the vicinity. A solution of one cup bleach to four litres of water should do the trick.
