Power Washing your house quickly and safely
Power washing is a quick effective way to clean your home if done correctly. If you just want to clean your home without having to paint it you must take care not to damage the paint or caulking by using too much pressure. Many pressure washers can produce over 3000 psi of pressure at the tip, which is powerful enough to gouge siding, erode cement or cut through skin, muscle and bone! So before we go any further lets discuss some safety points.
Power washing safety tips
- Know your machine: whether electrical or gas powered you should take the time to read the operation and safety manuals for your pressure washer. Familiarize yourself with the kill switch and other safety features
- wear safety glasses, goggles or face shield while pressure washing.
- Water conducts electricity: Use caution around service panels, meter bases, overhead wires, electrical outlets and exterior lights to prevent electrocution! Always be aware of where you are spraying and where you are going to spray next.
- Mufflers get HOT: If you are using a gas powered pressure washer always remember to avoid touching the muffler. When starting an engine it is common to place one hand on the engine to steady it while pulling the starter cord with the other. Many engines have mufflers located in a position that you might be tempted to place your hand to steady it when pulling the starter cord.
Never use the high pressure jet tip or the narrow fan tips close to the siding. Never direct the spray at yourself or others as the pressures generated by power washing are extremely dangerous. It is OK to use the high pressure tip to reach high areas on the house. Just be aware of the extreme pressures generated and use common sense in not allowing the jet to damage the house.
When installing or changing tips always point in a safe direction (at the ground) before pulling the trigger for the first time. (If the tip is not seated properly the water pressure will turn it into a projectile capable of breaking windows or causing injuries)
Pay close attention to where you are spraying. The high pressure will force water under or around doors and window and into wall vents, soffit vents and attic vents.
There are many cleaners available that are marketed just for power washing but an effective and economical alternative is Surf liquid laundry detergent mixed at the rate of about 8 to 16 ounces per gallon of water. If mildew is present add up to 32 ounces of bleach to each gallon of water. Wear protective clothing and eye protection. Apply using the low pressure siphon tip of the pressure washer or use a pump up sprayer. (Surf laundry detergent is biodegradable ~ if rinsed down with copious amounts of water neither it nor bleach is harmful to plants or animals)
Thoroughly soak one area or wall at the time with cleaning solution and allow it to work for three to five minutes. You can soak the next area down while you are waiting for the first area to work, just don’t let it dry before rinsing.
Once the cleaning solution has had time to work on an area for a few minutes rinse it down completely with clear water until all sign of soap residue is gone. Never let the cleaning solution dry on the wall as it will redeposit the dirt that had been loosened.
When power washing is completed inspect the entire house, especially around doors and windows to determine if any caulking or paint was damaged . Allow house to dry thoroughly before applying any caulking and paint.
Power washing can be a challenge for some but the benefits of a clean, attractive and well maintained home easily justify the time and expense of this project.
