Pressure washing can be very productive while being very dangerous for many reasons. You are working with gasoline, which can have explosive vapors. The lawn mower type motor can get very hot and the possibility of burning your hand increases when trying to move the unit after is has operated for even a short time. Remember, also that you are using a high-pressure system that should never be pointed at a person. Do not make the mistake of placing your finger near the tip outlet to determine if it is working properly since a digit can be sliced off in seconds. Always wear correct shoes, eye protection and other PPE's (personal protective equipment) that is recommended by the manufacturer or OSHA for these types of operations. Be careful and only operate if you know how to do so safely.

Once you have determined the correct tip to use (usually a medium fan tip) test the pattern in a corner or inconspicuous area to determine distance from the surface and the sweeping motion to use to be most effective. Make special note of any potential damage to grout line, aging concrete or other surfaces. Too close to the surface can be just as bad as being too far away. The best route is to begin to spray/sweep towards a drain or other suitable area for the water and debris to collect. If performed correctly, the surface should come clean without damaging the concrete. Be very aware of foot traffic, plants, mulch, gravel and other debris that could be blown in the wrong direction.

You will find that the more you pressure wash, the more effective you will become. Always follow manufacturer's directions carefully.
