Pressure washing is an effective way to rejuvenate your home’s exterior, removing layers of dirt, grime, mold, and mildew. It not only brightens up your property but also helps prevent long-term damage to surfaces like siding, decks, driveways, and fences. However, before you start blasting away with a high-powered stream of water, it’s essential to take a few preparatory steps to ensure a successful and safe pressure washing experience. Follow this checklist to get the most out of your pressure washing session and keep your home looking its best.
Step 1: Choose the Right Pressure Washing Equipment
The first step to successful pressure washing is selecting the right equipment for the job. Not all surfaces can withstand the same level of pressure, so understanding the options available is crucial.
- Pressure Washer Types: Pressure washers come in various strengths, measured in PSI (pounds per square inch). For example:
- 1,300 to 1,900 PSI: Ideal for cleaning vehicles, outdoor furniture, and delicate surfaces.
- 2,000 to 2,800 PSI: Suitable for general household tasks, including cleaning decks, siding, and fences.
- 3,000 PSI and Above: Best for tough surfaces like concrete driveways and stonework.
- Nozzle Selection: Most pressure washers come with interchangeable nozzles that adjust the spray pattern and pressure. Here’s a quick guide:
- 0-degree (Red): Produces a narrow, high-pressure stream. Effective for removing tough stains but should be used sparingly as it can damage surfaces.
- 15-degree (Yellow): Delivers a powerful spray, great for removing paint and stripping away heavy grime.
- 25-degree (Green): Ideal for general-purpose cleaning on most surfaces.
- 40-degree (White): Provides a wider, gentler spray, suitable for windows, siding, and other delicate areas.
By selecting the right pressure washer and nozzle, you can ensure that each surface is cleaned effectively without risking unnecessary damage.
Step 2: Protect Your Surroundings
Pressure washing can be messy, and the powerful water spray may damage nearby plants, fixtures, or outdoor furniture. Take time to prepare the area by safeguarding anything you don’t want to get wet or damaged.
- Cover Plants and Shrubs: Use plastic sheeting or tarps to cover plants, flowers, and shrubs near the work area. This will protect them from the high-pressure spray, as well as any cleaning agents that might be used.
- Move Outdoor Furniture: Relocate any patio furniture, grills, potted plants, and other items to a safe distance from the pressure washing zone. This prevents these items from being knocked over or accidentally damaged.
- Close Windows and Doors: Make sure all windows and doors are tightly closed to prevent water from entering your home. Double-check around doors with weatherstripping or seals to ensure there are no gaps where water could seep in.
- Turn Off Exterior Power Sources: For safety, disconnect or turn off outdoor electrical outlets, lights, or other electrical components that may be in the pressure washing area. Water and electricity don’t mix, so it’s best to be cautious here.
Step 3: Prepare the Surfaces to Be Washed
Once the area is secure, it’s time to prepare the surfaces you’ll be washing. Each surface may require a slightly different approach to ensure effective cleaning and prevent damage.
- Inspect for Damage: Before you start washing, inspect surfaces like wood siding, decks, and fences for any signs of wear, damage, or loose paint. Pressure washing can exacerbate existing damage, so it’s essential to address any issues first. For example, repair loose boards on a deck, or replace damaged siding panels before beginning.
- Clear Debris: Remove any loose debris, such as leaves, branches, or dirt, from the area you’ll be cleaning. For surfaces like decks or patios, use a broom to sweep away debris, and consider using a leaf blower for larger areas like driveways.
- Apply a Pre-Treatment (If Necessary): For surfaces with heavy stains, mold, or mildew, pre-treating with a cleaning solution can make the pressure washing process more effective. Choose a solution designed for your specific surface and apply it with a pump sprayer. Allow the solution to sit for 10-15 minutes before pressure washing. If using chemicals, be mindful of run-off and nearby plants.
Step 4: Test a Small Area First
Pressure washing can be a powerful tool, but it’s always best to test a small, inconspicuous area before cleaning the entire surface. This helps you determine if the pressure and nozzle settings are appropriate for the surface without risking visible damage.
- Adjust the Pressure: Start with a lower pressure setting, especially for more delicate surfaces like vinyl siding or painted wood. Gradually increase the pressure as needed, checking for signs of damage.
- Observe the Effects: After testing, check the surface for any signs of etching, paint removal, or other issues. If the test area looks good, proceed with confidence. If not, consider switching to a gentler nozzle or reducing the pressure.
Step 5: Pressure Wash the Surfaces Using Proper Technique
Now that everything is prepped and ready, it’s time to start pressure washing. To achieve the best results, follow these simple techniques:
- Hold the Nozzle at a Safe Distance: Generally, keep the nozzle at least 12-18 inches away from the surface you’re cleaning. Too close, and you risk damaging the material; too far, and you may not clean effectively. Adjust as necessary for different surfaces.
- Use Even, Overlapping Strokes: Start from the top of the area and work your way down. This prevents dirt from being pushed up into areas you’ve already cleaned. Use long, overlapping strokes to ensure full coverage and avoid streaks.
- Be Mindful of Angles: For surfaces like siding, aim the spray downward or horizontally to prevent water from being forced under the siding or into small gaps. This technique is essential for preventing water from seeping into your home’s structure.
Step 6: Rinse Thoroughly and Check Your Work
Once you’ve pressure washed all desired surfaces, it’s crucial to rinse thoroughly, especially if you used any cleaning agents.
- Rinse with a Low-Pressure Setting: Switch to a lower pressure setting or a wider nozzle and go over the surfaces with clean water. This helps remove any residue left behind by the cleaning solution and ensures a streak-free finish.
- Double-Check for Missed Spots: Walk around the area and inspect for any spots that may need additional cleaning. This final step ensures that you’re satisfied with the results and that the surfaces look as good as new.
Step 7: Clean and Store Equipment Properly
After you’ve finished pressure washing, take a few moments to clean and store the equipment properly. This helps ensure it’s ready to go the next time you need it.
- Flush Out the Pressure Washer: Run clean water through the pressure washer to clear out any remaining cleaning solution, preventing build-up that could damage the machine.
- Coil Hoses and Store Safely: Disconnect and coil up any hoses, and store them in a dry area. Inspect hoses for any wear or damage, and replace them if necessary.
- Store in a Safe Location: Store the pressure washer in a dry, sheltered location, away from extreme temperatures. This protects the machine and keeps it in good condition for future use.
Additional Considerations: When to Call in a Professional
Pressure washing can be a DIY task, but for larger homes, multi-story buildings, or delicate surfaces, hiring a professional might be the safer option. Professionals, such as Just Call Mikey, have the expertise and equipment to handle challenging jobs effectively, leaving your home looking fresh and spotless without the hassle.
By following these steps, you’ll be well-prepared for a successful pressure washing session. Pressure washing not only boosts curb appeal but also extends the life of your home’s exterior surfaces. With the right preparation and technique, you’ll achieve results that make your home look as good as new.
