Here at A Concord Carpenter we love tools and believe the right tool for the job can save you time and money, but ultimately you’ll get better results when you use the BEST tool for the job. When it comes to cleaning outdoors, nothing does a better job, faster than a pressure washer. But misuse of a pressure washer can have the opposite effect on your project. Check out these important tips on how to use a pressure washer.

Nozzle Choice

Nozzle choice is important to get the best results for the application you are using your pressure washer for. Nozzles are marked by degree and often color coated to delineate the width of the fan of the spray. A wide spray, for example 40-degrees, is good for soft material, like wood. A thin stream or a 0-degree spray is good for tough stains on concrete or to strip offending build up from a surface or weeds from cracks in driveways.

Spray Pattern

The spray pattern you use during operation is important and can have a major impact on the results of your wash. Start spraying from a distance of 4 feet and work your way closer until you get the desired cleaning effect. Don’t get too close to the work surface as you may gouge or damage the work surface. Once you find the appropriate distance maintain this distance throughout your cleaning.

You can work from top down or from the bottom up, but keep your pattern consistent and use an overlapping pattern to prevent streaking. Whether you choose to work from the top first or the bottom depends on the surface you are cleaning.

Be sure to spray your surface at an angle, a direct spray from a powerful pressure washer can force dirt and grit into the surface rather than wash it away. When rinsing a clean surface be sure to spray with the nozzle pointed down or away in the same direction to promote left over dirt and debris to flow down and away from the surface.

Detergents and Chemicals

If you are using a detergent, degreaser, or any other chemical to accelerate your cleaning you should prepare the area around your work surface and ensure you are wearing the appropriate Personal Protective Equipment (PPE)

To mitigate the effect of chemicals on your landscaping you can pre-soak your plants around the cleaning area with a generous amount of water to dilute any possible chemical contamination.

To thoroughly protect your plants and flowers you can set up tarps over them to prevent any direct contact with chemicals. If you do so, remember to use an opaque tarp and minimize the amount of time the plants remain under the tarp during hot days.

Eye protection should ALWAYS be worn during pressure washer operation and when using harsh chemicals gloves, long sleeve, and pants should be worn to prevent contact with skin.

Using a detergent is an important step when staining a deck.

Take extra care

A pressure washer is an extremely powerful tool and you should take extra care near windows, electrical components like lights and exterior outlets, and fragile components of your home or deck. The strength of the pressure washer could damage these parts of your home and worse could force water in and behind the exterior of the home accelerating rot and promoting mold.

Consider the direction of spray against some specific areas. Never spray up under clapboard siding or shingles. You could drive water up and under the protective surfaces of your home. Same concept goes for your roof, spraying up under shingles can drive water up and under your roof which could develop into a consistent leak and promote rot.

As I mentioned a pressure washer is powerful so be sure to wear PPE and treat the nozzle like a gun and NEVER point it at anyone or anything you don’t intend to spray. Also the kick back of the sprayer can be tough to handle so stay off ladders and ensure you have solid footing and handle the wand with both hands during operation.

Be cautious when holding key components that have sensitive contact areas. If you want to be extra cautious you can use tech grade ESD gloves. I recommend ESD Nitrile gloves that have microtextured fingertips that provide excellent grip on all surfaces. 100% nitrile gloves contain no natural rubber or silicone and meet stringent requirements for particles and extractables. In regards to handling try not to directly handle PCB or contact points. For a graphics card try to handle it from the corners or the heatsink. For a motherboard use the corners / sides. If you do not want to use full gloves you can also consider finger ESD cods. If you use your bare hands just have common sense and keep in mind when the contacts are.

I mistakenly refer to the measurement on the gloves thickness as millimeters, when in fact it is milli-inches. MIL stands for milli-inches and MM stands for millimeters. My bad. Though, that doesn’t change anything I say as inaccurate regarding smaller number = thinner glove.

If you’re trying to prevent fingerprints, wash your hands thoroughly with soap and water, paying particular attention to scrubbing the pads on your fingers. Dry them off well. Then handle the components by the edges, as I demonstrate in all of my computer building videos. If you happen to see a fingerprint, stop. Go wash your hands again! This is a much better plan than using any kind of glove.

Remember, handle all parts by the edges and there is no place for fingerprints to be left behind! I demonstrate this in every single computer build video I’ve ever done.

If you’re trying to prevent cuts, these gloves are all too thin to provide any protection from that. Work slower and more carefully to avoid injury. Or put on band-aids prematurely in areas of your hands that you feel you are most prone to be cut.
