There are some easy tips for how to clean your patio or driveway using a Karcher pressure washer. When selecting the pressure washing that will be most effective, getting a washer with at least 3000 PSI will provide you with sixty times the water pressure that a person gets from their garden hose.
Several attachments are included with most washers. If you have a long driveway you may want to purchase a longer hose so you do not have to keep moving the washer. You will need a 15 degree wand. These wands are specifically designed for concrete driveway and patios. When pressure washing a different surface, testing a corner of the driveway first to make sure it will not be damaged will be one of the steps to take before you begin.
The most effective washers are large and powerful machines that look like commercial units. They have 10″ tires and many of the same features found on industrial equipment. Using protective gear with the machines will keep you safe. Protective eye goggles and heavy industrial gloves will keep debris from flying into your eyes and causing injury. The attachments should be secured tightly and tested before increasing the pressure being used.
Prior to beginning the washing process there are a few steps that will make cleaning more effective. Clean the driveway, removing loose dirt, toys and debris that in on or near your driveway. When your driveway has been swept, use a commercial stain remover made for asphalt, cement, or concrete on heavy spots. The remover should be left on the spot overnight to completely remove the stain.
Pre-treating before washing is important and there are solutions are made which will break up grease and wash it away easily. The pre-treatment solution is left on the drive for five to ten minutes prior to beginning the pressure washing process.
After making all of the preparations you will be ready to begin pressure washing your driveway. Starting at the top of area, use overlapping motions and work your way down the driveway. Once the driveway has been cleaned, let it dry for at least 24 hours. Once the surface has dried apply a sealant to protect it until the next cleaning.
