One of the most efficient and best ways to get a car wash cleaning is by pressure washing. Pressure washing is using a highly pressurized water blast of water. By pressure washing, you’ll be able to remove grime, dust, mud, and dirt from the exterior of your car. There are different factors that go into the difference between a normal hose off and a pressure wash.
Did you know the softness of your water can affect how easily soap suds form? Calcium from water creates soap scum that will form instead of suds and may require more soap to get the necessary clean it needs. A standard garden hose puts out somewhere between 40 to 50 PSI. When cleaning your exterior, you want to be between 1200 to 1900 PSI. The nozzle of your water source is important to keep in mind because it could potentially damage your car if you use something not suitable for cars. A single stream of water could remove paint!
Another thing to keep in mind is that you want to avoid aiming the nozzle too close to plastic trim pieces. When going through an automatic car wash, the machine is put on a certain setting and doesn’t stop until it goes through the cycle. If a detailer does the pressure washing by hand, they pay attention to the details and key areas to avoid while using the pressure washer on your car.
