Pressure washers are extremely helpful when it comes to cleaning large surface areas that would be difficult to wash by hand. They run either on gas or electricity and pump water through a narrow nozzle to emit a powerful flow of water. To pressure wash a surface, you'll need to select the right washer for the job. Electrical pressure washers are best for everyday cleaning, while gas and commercial washers will provide more power for tougher jobs. When using a pressure washer, keep it angled away from you, and start with the lowest power setting and widest nozzle attachment before increasing the flow of water.
[Edit]Steps
[Edit]Choosing the Right Pressure Washer
- Use an electric pressure washer for simple, everyday cleaning. An electric pressure washer is a basic washer that typically emits water between 1300 and 1900 psi. It's a good choice if you're planning on performing regular washes around your home. A typical electric pressure washer is good for washing cars, patio furniture, decks, exterior walls, or driveways.[1]
- Psi stands for pounds per square inch, and is used to measure pressure. The higher the psi, the greater the pressure.
- You can buy a pressure washer at any big box hardware store. Some smaller hardware or cleaning supply shops may have them as well.
- Opt for a gas-powered pressure washer for heavy duty jobs. Pressure washers with a gas engine run on unleaded gasoline and produce a flow of water between 2000 and 3100 psi. They are also more portable than electric pressure washers, since they don't need to be plugged in. They're much better than electric washers when it comes to cleaning stone, wood, and metal. Get a gas-powered washer if you need to clean stronger or tougher surfaces.[2]
- Some gas-powered pressure washers emit a lot of fumes and cause a lot of noise when they're running. If you want a silent and clean pressure washer, avoid getting a gas-powered washer unless you really need the extra power.
- Pressure washers with high psi settings will be more expensive than standard pressure washers since they're capable of scouring tougher surfaces.
- Buy a commercial washer with a high psi for the strongest wash. Commercial washers are almost universally gas-powered, but tend to be bigger than standard gas-powered washers. They reach a psi of 4,000 or higher, and are the only choice if you want to remove graffiti, strip paint, or clean commercial-strength concrete or metal.[3]
- Get a pressure washer with a soap dispenser for home cleaning. Some pressure washers come with a soap dispenser that can mix soap into the water as you're washing something. If you know that you're going to be consistently cleaning something with soap, look for a pressure washer with a built-in soap dispenser. It will come in handy if you want to clean a car or picnic table every week or so.[4]
- Always run a pressure washer with water for a few minutes after using the soap dispenser to wash your hose and nozzle out.
[Edit]Washing a Surface
- Wear protective eyewear, thick boots, and heavy-duty gloves. Pressure washers emit a powerful spray that will not only send water flying all over the place, but can knock up loose pebbles, small rocks, and dirt before making them airborne. To protect your eyes and hands, wear protective eyewear and heavy duty gloves before you use your pressure washer.[5]
- Heavy boots will protect your feet and keep them dry at the same time.
- Attach the widest nozzle that you could use on your surface. Nozzles for pressure washers are color-coded to indicate the size of the spray pattern. Start with the widest nozzle based on your surface area to make sure that you don't expose your surface to unnecessary force and that it can handle the pressure washer's flow without any damage occurring. Once you've tested a wide-angle nozzle, you can determine whether or not you need a stronger spray.[6]
- White nozzles are 40 degrees.
- Green nozzles are 25 degrees.
- Yellow nozzles are 15 degrees.
- Red nozzles are 0 degrees. They will emit an incredibly strong stream of water, so use them sparingly.
- Black nozzles are designed to dispense soap, and restrict the pressure of the liquid coming out.
- Hold the nozzle at an angle away from you, towards your surface. Never place your nozzle at a 90-degree angle to your washer. The ricochet and splashing created by your washer will be tremendous. Hold your hose out at a 20-45 degree angle away from you with the nozzle pointed away from your surface.[7]
- Turn your pressure washer on and set it to the lowest power setting. Connect the hose to your pressure washer and turn it on. Hold the nozzle away from you in the direction of the surface you want to clean. With a firm grip on your handle, turn your pressure washer on and pull the trigger to start cleaning. Start in an inconspicuous section of the area that you plan on cleaning in case your surface area gets damaged from the initial flow of water.[8]
- Starting on a lower power setting will ensure that you don't damage your surface with the initial blast of water. You can always turn it up once you've started.
- Adjust the distance between your surface and the nozzle. As soon as the water starts coming out, you'll be able to see if your washer is successfully removing dirt or damaging your surface. If splashing is a problem, sharpen the angle between your nozzle and the surface that it's cleaning to direct the water away from you. If your washer isn't cleaning the area, move the nozzle closer to the surface.[9]
- The narrower your nozzle is, the farther away you can be from your surface. If you need to clean the top of a tall wall or the underside of a roof overhang, don't adjust your distance. Instead, swap your nozzle out for a tighter option.
- Work horizontally, starting at the top of your surface. Whether it's a wall, car, or patio furniture, start spraying from the top of your surface. Water will trickle down, which will make cleaning the sections beneath your spraying area easier. Start at the top and work horizontally until you've fully cleaned a row of your surface area. Then, lower your washer and move in the opposite direction, moving parallel to your original line.[10]
- Move your pressure washer slowly as you navigate your intended surface to ensure that you don't lose control of the hose.
- It may take multiple applications before you clean a surface completely.
[Edit]Avoiding Common Mistakes
- Avoid electrical lines, outlets, and light sources. Water and electricity do not mix, and it is dangerous to get electrical equipment wet. Don't use your power washer anywhere near electrical equipment or active power lines. If you have to wash an area with an exterior outlet, cover it with multiple layers of duct tape to keep water out.[11]
- Keep your washer's engine behind you as you move around during your pressure washing. This will keep water from getting in the engine.
- Cover shrubs, gardens, or air conditioners with drop cloths. Pressure washers obviously produce quite a bit of force. Even if you don't hit sensitive areas with the pressure washer directly, the ricocheting water can still cause damage. Cover areas that you wish to protect with a heavy drop cloth. Lay it on top of the area you want to protect, and weigh down the corners with heavy objects or tie it down with duct tape.[12]
- A drop cloth will not protect sensitive areas if you aim your nozzle directly at them. It will merely prevent incidental damage from unwanted splashing.
- Don't use your pressure washer on a ladder or unstable surface. Pressure washers create a lot of kickback when you turn them on. For this reason, using the washer on a ladder or unstable surface can be extremely dangerous. Besides, pressure washers are strong and you should be able to hit a hard-to-reach area with higher power settings and a thinner nozzle from away.[13]
- Clean out water lines after using soap in your pressure washer. If you're using a soap dispenser, soap scum can dry up in your water lines after you're done using your washer. Clean your pressure washer by refilling it with water and running it for 3-5 minutes before emptying the tank and wiping it down with a microfiber cloth. Inspect the lines and hoses on your washer for damage before each use.[14]
- Some pressure washers are designed to be taken apart for cleaning. Refer to your washer's manual to see how to take it apart.
- If you have a gas-powered washer, you may need to change out the oil regularly.
- Store your pressure washer in a warmed section of your home during the winter to prevent water lines from freezing.

You should see how my buddy Wesley Virgin's report starts with this shocking and controversial VIDEO.
ReplyDeleteWesley was in the military-and soon after leaving-he revealed hidden, "SELF MIND CONTROL" secrets that the CIA and others used to get anything they want.
These are the same methods many famous people (notably those who "come out of nothing") and top business people used to become wealthy and famous.
You've heard that you use less than 10% of your brain.
Mostly, that's because most of your BRAINPOWER is UNCONSCIOUS.
Perhaps this expression has even taken place INSIDE OF YOUR own head... as it did in my good friend Wesley Virgin's head about seven years ago, while riding an unlicensed, beat-up trash bucket of a vehicle with a suspended driver's license and on his banking card.
"I'm very frustrated with living check to check! When will I get my big break?"
You've been a part of those those types of questions, right?
Your success story is going to be written. All you need is to believe in YOURSELF.
UNLOCK YOUR SECRET BRAINPOWER
It is also helps to have access to a hot water machine if you have to clean any oily spots from a driveway. Driveway pressure washing is usually done with a hot water unit if operator wish to get those stubborn oily and transmission fluid spots.
