Pressure washing is the application of high-pressured water at very high pressure to remove tough dirt, loose clay, grit, mud, debris, odors, chewing tobacco and other debris from surfaces and non-porous objects like concrete surfaces, vehicles and buildings. Pressure washers are generally powered by electricity or gasoline. They come in different sizes and types. LBL Pressure Washing and House Wash – Pressure Wash
Most pressure washing equipment is operated with the help of a high-pressure nozzle. However, there are some machines that require a lower nozzle to achieve effective cleaning. It is important to ensure that the machine you are buying can handle the task you need to do. A high-pressure washing unit with a low gallon capacity is best for tasks like exterior surfaces where it is not necessary to clean the entire surface. For interior surfaces, a small electric-powered unit or gas-powered unit is advisable.
When pressure washing decks, it is advisable to purchase a pressure washer that has an attachment for cleaning deck boards. For plastic decks, a vinyl-coated deck cleaner is better as it avoids damage to the surface. Pressure washers are generally available in two different lengths; seven gallons for smaller cleaning and forty gallons for larger projects. The right one for your project depends largely on the size and texture of the material to be cleaned. Some pressure washing units come with optional accessories such as powerheads and skid-free brushes for extra cleaning.
There are many kinds of pressure washing tools available in the market today. Their main function is to loosen and remove dirt, grease, muck, moss, sand, mud, rust, tree sap, pollen, fungus, algae and leaves from floors, walls and other surfaces. The two types of pressure washing machines are electric and gasoline. Pressure washers with gasoline engine use gasoline to power the rotary brushes and suction cups. Electric pressure washing machines are often used interchangeably with vacuum cleaners.
There are many things to consider when choosing a pressure washer for your exterior cleaning. First, make sure the machine will handle the type of material to be washed. The best machines are those that can handle both hard and soft materials, and they also must have the capacity to handle very heavy-duty equipment without breaking down. They should be able to withstand high pressures and strong winds. Exterior pressure washing equipment is available in both gasoline and electric forms.
Other considerations include whether the exterior unit needs to have its own water source and whether it has an exhaust. If the machine cannot lighten or rinse the dirt by itself, then an external source of water is required such as a garden hose or a sprayer hooked up to a garden hose. Most homeowners prefer to have the exhaust cleaned by professional contractors because it eliminates the possibility of carbon monoxide leaks from the pressure washing job.
It is important to note that mildew and mold need not be cleaned by water alone. A mild scrubbing will suffice. Many homeowners like to use a combination of water and mild soap, with coarse sandpaper added for tougher stains. Some homeowners prefer to have the pressure washing job completed with a rinse using hot soapy water. Whatever method homeowners choose to complete the task, they should always use a scrubbing brush or cloth to gently but thoroughly clean the surface of dirt and grime.
When power washing a driveway, there are a few extra steps that are necessary. The driveway surface should first be covered with a plastic sheet until the power washing process begins. Then a heavy-duty abrasive material should be used on the driveway to remove all debris. Then a medium-duty truck-mounted brush should be used to apply the chemical. Finally, hot water should be applied to the surface with a power washing machine’s nozzle.
