Pressure Washing: The Ultimate Solution For Deep Cleaning

While there may not be a magic wand that can banish years of mildew, mold, and dirt from exterior walls, walkways, driveways, and other surfaces around your home, professional cleaning with the help of a high-powered pressure washer is the next best thing. These tools can remove stubborn stains and grime from a wide variety of outdoor surfaces without damaging them, and they’re an effective way to improve curb appeal and protect your investment in your property.

But there are a few things you should keep in mind before you try to tackle this project yourself, and it’s usually best to leave the work to Bethesda power washing professional. For starters, it’s important to understand the difference between power washing and pressure washing. While both tools use high-pressure water to blast away debris and stains, the difference is in the temperature of the water, how much force is delivered by the nozzles, and how quickly the water flows through the machine.

Power washing uses a pump powered by an electric or gas engine to accelerate water, then pushes it through a hose at high kinetic energy. This high-pressure water is then directed by nozzles at different settings to produce a wide or narrow spray, as well as different motions, such as swirling or straight streams. Power washers also have attachments like brushes and spinning wands that add a bit of extra scrubbing power to break down stubborn buildup and residue.

When you’re ready to tackle a home cleaning project, start by gathering all of the necessary supplies. You’ll need a pressure washer equipped with the right nozzles for the type of surface you’re cleaning, as well as soap or detergents. It’s best to choose products that are specifically designed for the type of surface you’re cleaning, and it’s generally a good idea to test your cleaning solution on an inconspicuous part of the surface before attempting a full-scale clean.

Another factor to consider when choosing a pressure washer is the PSI and GPM ratings. PSI stands for pounds per square inch, and this metric measures the amount of force exerted by the nozzles. Contractors and professionals tend to favor residential-rated gas machines with a 2,600-3,400 PSI and 2.3-2.6 GPM, which provide sufficient power to effectively clean most outdoor surfaces.

Once you’ve got the right equipment, it’s time to start planning your project. Before you begin, make sure to close any windows or doors in the vicinity of the surface you’re cleaning, and cover outlets and doorbells with duct tape to prevent water from seeping inside and mixing with electricity. You should also turn off any lights or appliances on the area you’re cleaning, as these items can be damaged by excessive water pressure. Once you’re ready to start, remember to hold the nozzle at least four feet from the surface and start at a low setting before gradually increasing the pressure as you move along.
