When using your power washer, make sure you are using the right tips and nozzles for the jobs you are doing.
Most washers come with different spray tips to lower the water pressure for cleaning and raise the pressure for high-powered jobs like rinsing.
Tips also come in different angles. The smallest angle typically gives the most power, and the largest angle gives a lighter stream. Small angles can be used for powering off stains while the larger angles can be used for light washing or soaking.
