Time it Right
Force per unit area washers use a lot of h2o. If your water is supplied by a well, information technology's all-time to tackle this job when other water use is calorie-free. You don't want to deplete your well on laundry day or when your have a house full of guests. And if you're in a drought, you may want to postpone for a few months.

Tarp your plants
Physical detergent can impairment plants; before you begin pressure washing, comprehend them with tarps. I used canvas drop cloths, just they can be expensive. For a inexpensive, lightweight option, use a roll of painter'south plastic. Remove the tarps as soon equally possible to avoid overheating the plants.

Blow abroad droppings
Moving piles of debris with a pressure washer is a waste of time and water. Instead, utilize a leaf blower to clear away smaller debris like leaves, rocks, sticks and mulch. You tin can use a broom, simply a leaf blower is faster and easier. Don't rush this step, and clear as much as possible.
iv / 19
Wear safety gear
Pressure level washers are loud, the water and other debris tin splash back in your face, and you'll be stepping around slick, soapy water. Ever wear condom glasses, hearing protection and close-toe shoes with skilful traction. A powerful pressure level washer tin really cut skin. Utilise information technology with caution, and keep it away from children.

Bigger is faster
The greater the pressure washer's psi rating, the faster the cleaning job. I tested iii pressure level washers: 1,600, ii,300 and 3,100 psi. At that place'southward no doubt that electric pressure washers from ane,300 to 2,300 psi tin can launder a concrete driveway, merely it'll accept longer. If you accept a large driveway with lots of stains, you'll want more power to do the job faster. I chose the 3,100-psi gas pressure washer and cutting the job time in half.

Purge the hose
Once you've continued the garden hose from the spigot to the pressure washer, don't exist too eager to plough on the pressure washer. Instead, clasp the trigger for roughly 30 seconds until a nice, steady stream comes out. This releases the air from the hose and preps the machine for a stiff blast. This is a good idea for proper pressure level washer maintenance.
7 / 19
Choose the right nozzle
Nozzles are calibrated in degrees, and the lower the number, the narrower and more powerful the stream. I experimented with diverse nozzles and settled on three: For dousing the concrete with detergent, a 65-degree worked well. For the actual cleaning, a 25-degree was fastest. For tough areas, I used a 15-degree nozzle. Choice upward a 5-in-one dial nozzle (almost $25 at abode centers) to make changes quick and easy.

Concrete under the gun
Y'all would never use a 0-degree nozzle to wash physical, but I couldn't resist giving it a endeavour. Make sure you're buying the correct pressure washer. I used a 3,100-psi gas pressure level washer and placed a 0-degree nozzle just a few inches from the concrete. In seconds, I carved a zigzag line with ease. Afterwards 45 seconds, the pressure washer left a minor crater. Pressure washers can deeply damage concrete, only it'll accept some endeavour. In normal circumstances, all you really need to worry about is light surface etching.
9 / 19
Experiment on a less visible spot
If you concord the nozzle too close to the driveway, the pressure level can etch the concrete surface. The distance depends on the power of your pressure washer and the nozzle you lot're using. Try experimenting on an inconspicuous spot and run across how shut yous can get without damaging the concrete.
Plan alee and piece of work from acme to bottom. If your roof, siding and retaining walls need to be done, do them kickoff. Otherwise, dirty water will run off those surfaces and ruin your clean driveway.
10 / 19
Use a detergent
Concrete detergent is incredibly effective. I tried pressure washing without it, and the result didn't come up close. It helps remove stubborn oil, pigment and dirt stains. I used Zep Driveway & Concrete Pressure Wash detergent, only many smashing options are available. New pressure level washers often include a soap tank to use the detergent. Moving ridge the wand back and along roughly 8 in. off the surface to create a nice lather. Let it sit for 10 minutes and so wash. Don't pour bleach or other chemicals into your pressure washer lather tank.
11 / nineteen
Spot-treat stains
Before you clean the unabridged surface, spot-treat the oil stains. I saturated these stains with diluted physical detergent solution from a spray bottle. Let the soap sit down for 10 minutes, and then rinse with the pressure washer. Some stains are tough to remove—paint stains make clean upwards quickly, only oil and rust stains take longer. If your stain isn't disappearing, treat it a few more times with a less diluted solution.
12 / 19
Start at the tiptop
Showtime at the high terminate of your driveway and work your fashion down. You don't want muddy water running over the places you just cleaned. That might sound obvious, but it's easy to start at the lesser without thinking about it. Also, be sure to park the pressure level washer near the loftier spot so you're dragging the hose backside you lot, rather than constantly kicking it out of your way.
13 / 19
Work in small sections
If y'all spray your unabridged driveway with soap all at once, it'll settle and dry before you lot can wash information technology off, which could leave white stains and streaks. Instead, lather and launder in x 10 10-ft. sections. On my driveway, I institute the joints in the physical to exist a natural guide.
14 / 19
Move toward the edges
Whether y'all're applying the soap or washing, showtime at the center of the driveway and work your way toward the edge. If you're using a nozzle, sweep the water dorsum and forth.
15 / 19
Extend your reach
Pressure washers are no fun to lug effectually. Do yourself a favor and buy a pressure washer extension hose. They come in 25-ft. and 50-ft. lengths ($45 to $75). I attached a 50-ft. hose to the 25-ft. hose that came with the automobile.
sixteen / xix
Get a surface cleaner
It takes a lot of time and effort to clean a driveway with a nozzle. You lot can cut both in one-half by using a pressure level washer surface cleaner. And they're affordable, ranging from $twenty to $90. The one I used price $88 online and was worth every penny. As you employ information technology, pull it from side to side rather than pushing information technology. Also, concord the wand upright to avert putting pressure on your back.
17 / 19
Rinse off your plants
Even with a tarp, soap can still find its fashion onto your plants. The plants besides can blot the soapy runoff at the roots. When y'all're finished pressure level washing, rinse the plants around your driveway with a garden hose.
eighteen / 19
Wash edges with a nozzle
The surface cleaner doesn't clean the edges forth retaining walls, posts or other structures, so y'all have to clean those with a nozzle. Use a 25-degree nozzle for deep cleaning and a xl-caste nozzle for rinsing away standing water.
19 / 19
Protect your driveway with a sealant
Later you lot've done the work to clean your driveway, consider sealing it. A proficient sealer will protect your driveway, assist it last longer and make future cleaning much easier. Be certain the driveway is dry before you lot begin.
