What PSI Pressure Washer Do I Need to Clean Concrete? You may wonder what psi pressure washer do I need for concrete cleaning. However, it’s important to know that the more powerful the pressure washer, the more damage it will cause. In fact, too much pressure will cause concrete to crack and crumble. If you’re planning on cleaning a concrete patio, it’s best to use a pressure washer that produces about 3000 PSI.
Before cleaning your concrete, prepare the area by removing any loose debris. If necessary, use a degreaser with a low-pressure nozzle. Make sure it has degreasing agents and use it to scrub the concrete. Apply the detergent solution to the entire surface and wait at least 10 minutes before you use the pressure washer to rinse it off. While paint stains are easy to remove with a pressure washer, oil and rust stains will take more time to clean. In these cases, you may want to use a diluted solution and repeat the process as necessary.
For general cleaning jobs, a gas-powered pressure washer is adequate. However, larger pressure washers can be too powerful for most domestic cleaning tasks. Some homeowners decide to buy the best home pressure washer they can afford and rent a more powerful one for concrete cleaning. You should also purchase or rent the proper power washer nozzles. High-pressure, wide-angle, and low-pressure nozzles are essential for concrete cleaning.
