1. Power washing is a great way to clean your exterior surfaces without having to use harsh chemicals. Using a pressure washer, you can easily remove dirt, grime, stains, and mildew from your home's siding and exterior wood trim. You can even use a pressure washer to clean windows, doors, and decks. However, using a pressure washer can be dangerous if not done properly.

2. When you're planning on cleaning your home's exterior surfaces, make sure you have the right equipment and know how to use it safely. Pressure washing machines vary greatly in price and quality. A high-quality machine should have a tank capacity of at least 50 gallons, an electric motor, and a nozzle attachment. Make sure you choose a model that includes a safety shutoff valve. Safety valves prevent water from being sprayed onto hot surfaces and can save lives. If you don't have access to a professional-grade pressure washer, consider renting one instead. Renting a pressure washer is much safer than trying to do the job yourself.

3. Before you begin, check your local building codes regarding pressure washing. Many municipalities require permits before you can perform any work on your property. Check with your local building inspector to find out what requirements apply to you. You may need to hire a contractor to help you get the permit.

4. To avoid damaging your property, follow these simple steps. First, turn off the electricity to your home and disconnect the gas line. Next, open the faucet to drain excess water from the system. Finally, wait until the pressure is turned down to its lowest setting. Then, spray the surface to be cleaned. Be careful not to spray the surface directly after the machine has been turned back on. Wait until the water pressure is completely off again.

5. After you've finished cleaning your home's exterior, rinse off the pressure washer thoroughly. Don't leave the hose running while you're cleaning. Turn off the water supply and let the hose run dry. If you plan to paint your home later, leave the hose empty. Otherwise, fill it up with fresh water and store it where it won't freeze.
