3000 psiTo clean concrete effectively, use a power washer with a pressure rating of at least 3000 psi and a flow rate of at least 4 gallons per minute (gpm).
The greater the pressure washer’s psi rating, the faster the cleaning job. There’s no doubt that electric pressure washers from 1,300 to 2,300 psi can wash a concrete driveway, but it’ll take longer. If you have a large driveway with lots of stains, you’ll want more power to do the job faster.
The most versatile category of pressure washers, those ranging from 2,000 to 3,200 PSI effectively clean cars (including the most well-used off-road vehicles), home siding, fences, boats and grimy garage floors. Those closer to 3,200 PSI work effectively on tough stains, too.
Light-duty pressure washers are rated at 2,000 PSI or less and are suitable for cleaning automobiles, motorcycles, boats, bicycles and all-purpose cleaning.
In general, the pressure you need to clean your driveway is around 3000 psi. Ensure that the pressure washer also has a good flow rate, if possible, around 3 GPM. This should be sufficient to clean your driveway.
For cleaning a wooden deck, you’ll be best served by using the lowest pressure setting that’s still effective. For soft woods like cedar or pine, this is usually about 500 to 600 psi. For harder woods, it can go up to 1200 to 1500 psi. Never get closer than 12 inches from the deck unless you’re using low pressure.
2000 PSI or less is preferred to wash a car. You can use pressure washers with more power but it can be damaging to paint above 2500 PSI. Pressure washer tips that spread the spray out can help reduce the potential for damage at higher pressures.
After some online research, I discovered that it is possible to damage the concrete if you’re not careful. If you use a pressure over 3,000 PSI, or if you hold the nozzle real close to the work, say an inch or two, you have the potential to loosen mortar or etch lines into the concrete.
Depending on the task at hand you should be looking for a pressure washer that has a range of between 1300-2300 PSI. This range of pressure should be enough for removing common problems, like dirt, grime, oil, and stains.
What kind of pressure washer do you need? Power washers come in two basic types – gas and electric. Gas will give you more power, but you really only need 1300 to 1600 PSI for most exterior cleaning needs, including vinyl siding. Gas pressure washers usually range from 2000 – 4000 PSI and cost more than electric.
For cleaning your house’s driveway, you need a pressure washer set to 2,500 to 3,000 psi. For other areas, like the vinyl sidings, decks, or glass, the pressure should not exceed 1,500 psi. For soft materials, like softwood, you should use even lower pressure, around 500 to 600 psi.
What is the ideal PSI for a pressure washer? Depending on the task at hand you should be looking for a pressure washer that has a range of between 1300-2300 PSI. This range of pressure should be enough for removing common problems, like dirt, grime, oil, and stains.
The Greenworks 1800 PSI (GPW 1803) is a good entry-level electric pressure washer. With its included array of nozzles (below) it can do a wide range of cleaning tasks, from washing cars to stripping paint (at a slow rate).
The quick answer is yes, power washing can degrade a concrete surface. The top reasons for pressure washing damage are using the wrong nozzle, excessive pressure, spraying too close to a concrete surface and holding the nozzle on a particular spot for too long.
People frequently do not realize that you can actually damage your concrete driveway, patio, or other concrete areas by pressure washing. However, using a pressure washer with the incorrect tip or using too much pressure or a combination of the two can etch concrete.
This Ryobi model’s pressure rating of 2,300 psi is very high for an electric pressure washer, as most are in the 1,800 to 2,000 psi range.
Ensure proper cleaning by spraying concrete with bottle of spray degreaser, keeping a distance of 6 inches from surface. Scrub degreaser into concrete using stiff brush or pressure-washer attachment tool.

Simply fill a spray bottle with equal parts water and vinegar (or water and baking soda), and add a little bit of liquid dish detergent. Spray the mixture on your concrete surface and let it sit for about 30 minutes. Then scrub and rinse your concrete.
