The terms power washing and pressure washing are often used interchangeable. But, the actual truth is that there are not quite the same thing; they are similar but at the same time they are different. In this article we will explore the difference between pressure washing and power washing, looking at the most common uses for each of them. Pressure and power washing are really the same but different; so if up until now you didn’t know there was a difference, you are forgiven!
The basic function of pressure and power washing is the same; they both used water that is highly pressurized to remove dirt from hard surfaces. There are some key differences between the two methods of cleaning exterior areas, and the method you use depends on what it is you are trying to get clean.

Power Washing Versus Pressure Washing
Both systems use about the same amount of pressure, the amount of pressure used for washing depending on the type of machine you have; if you hire an industrial pressure washer it will work at a higher pressure than one that you could buy at a hardware store. There is one key difference between the two methods of cleaning, both creating powerful streams of water that can remove ground in dirt and stains. The difference is that a pressure washer uses cold water whereas a power washer will use hot water.
Power washing uses hot water under extreme high pressure to get rid of surface dirt and grime in outdoor areas. The use of hot water means that it is possible to get rid of even really ground-in dirt and materials that have stuck onto surfaces over time. Power washing is great for removing mold and mildew and salt stains from outdoor furniture and decks; it’s also great at removing oil stains from decks and driveways. Due to the added heat as well as the power of the washing unit, it is also effective at removing chewing gum from sidewalks. Power washing is also used for roof cleaning and for the removal of moss and weeds. Hot water can kills the weeds and moss and stop them from growing back. In short, power washing is really heavy duty, and is used where cold water, even at the highest of pressures, won’t be effective.
Pressure washing is just like power washing, except that the water used is cold. Most likely you have tried your hand at home with a pressure washer or have called in roof cleaning experts who used pressure washing for the job. Despite the fact that the water used is tepid or at room temperature, it is still a fantastic way at cutting through dirt and grime in outdoor areas. It might not get rid of stains on your patio, and it will have a tougher time cutting through moss and weeds and getting rid of them effectively.

There are tons of situations in everyday life where you will see both power and pressure washing machines at work. Your street cleaners sit on ride-able pressure washers, and your bus station or terminal will be pressure washed down at the end of the night. If you spot a cleaner trying to get rid of graffiti off the side of a building, he however will most likely be using hot water and a power washer that will cut through the oil-based paints that were used when the graffiti was sprayed. Sidewalks and walkways are regularly pressure cleaned, although this often happens during the night or early hours when you will still be asleep. All public areas are regularly cleaned in this way such as open air plazas and stadiums, disinfectant being added to the solution during this time of the Covid-19 pandemic to ensure that all our communal areas are kept free from the virus.
Some surfaces are best cleaned with cold water only, as the use of a power washer with very hot water could actually harm or partially melt the surface. Before hiring equipment to try out power or pressure washing at home, always conduct some research to ensure that you choose the best method. And when in doubt, call in your local roof cleaning or power washing team for the job.
