During the cleaning process, a driveway requires a moderate water flow rate and a reasonable amount of pressure. Most professionals recommend using around 3000 psi to effectively remove old grease stains and other stubborn dirt. If you use less pressure, the cleaning process will take longer and will yield a less-than-optimal result. So, how much psi do you need for a good job?
Whether you have a concrete driveway or a brick one, the pressure washing process will require a few basic steps. First, remove all loose debris and weeds before applying the pressure washer. Attach the pressure washer nozzle to a 25-degree nozzle. Next, scrub the driveway using a broom or garden hose. If you have stubborn stains or a dense layer of moss, you can use a degreaser to break up the greasy buildup.
To remove stubborn stains, you can use soda instead of pressure washer. Simply add the soda to the dirt area and allow it to sit for 30 minutes. You can also use a water brush to remove stubborn stains. Pressure washers are great for cleaning driveways and other surfaces, but you need to know which one to use. You can also use baking soda on the driveway to remove stubborn stains. While baking soda is an older solution, it is less harsh on plants and flowers around your house. If you use baking soda to clean a driveway, make sure to use it only on the surface of the driveway.
Before you begin power washing your driveway, be sure to read the manufacturer’s user’s manual thoroughly. If you’re not familiar with pressure washers, you may want to start with an area that is less visible. Using too much pressure can be dangerous. Taking frequent breaks will help you avoid accidents. And don’t forget to wear safety goggles. If you’re new to power washing, be sure to wear protective eyewear and work gloves.
