Make sure the pressure washer you choose has a good PSI. Typically, it measures around 2,000 to 2,800 for the gas-powered ones, whereas electric options might be only 1,300 to 1,700 PSI. You’ll want to consider what you will primarily be pressure washing when looking for a pressure washer; for instance, cleaning the driveway requires about 3,000 PSI, but cleaning a house exterior only needs around 1,500 PSI.
It’s also important to know how to properly use the pressure washer. If you get too close or use too high of a pressure, you can cause damage to concrete or siding. Take the time to learn how to properly use your pressure washer.
When pressure washing your house, avoid cleaning in direct sunlight. Spray your cleaning agent first and let it sit for 5 to 10 minutes. Change the nozzle to a 25- or 40-degree tip and wash away the detergent while holding the wand at least 1 foot away from the house.
