If the vinyl siding on your home is beginning to appear grimy or dulled, it’s a definite sign that it’s time for it to be cleaned. Power washing is perhaps the best method for getting rid of dirt, mold, algae, and old buildup. It’s quick, effective, and when performed correctly, completely safe for your siding.
Not a clue where to begin? Don’t worry this guide will take you through it all step by step. Whether you’re a seasoned DIY-er or a first-timer, this step-by-step guide will have your house looking like new. Or, if you’d prefer to let the experts handle it, pressure washing services such as Pressure Washing Frederick MD are always standing by.
Why Clean Vinyl Siding in the First Place?
Vinyl siding is durable, but it is not entirely resistant to the elements. With time, dirt, pollen, mold, and mildew can accumulate, particularly in shaded or moist areas. Apart from being dirty-looking, this accumulation can gradually devour the integrity of the siding, reduce its lifespan, and even influence the indoor air quality if mold becomes a problem.
And who doesn’t enjoy the freshly cleaned look? Clean siding gives you an instant curb appeal and increases your property value.
What You’ll Need to Power Wash Vinyl Siding
First, grab your equipment. Here’s your minimum requirements list:
- A pressure washer (gas or electric)
- A 25-degree or 40-degree nozzle
- Cleaning solution (available vinyl siding cleaner from the store or homemade)
- A garden hose
- Protective equipment (gloves, safety glasses)
- Drop cloths or plastic to cover plants and electrical components
Pro Tip: If you don’t have a pressure washer, you can borrow one from most hardware stores.
Best Cleaning Solutions for Vinyl Siding
You’ve got some choices when it comes to cleaners:
Available-at-stores siding cleaners
These are made especially for vinyl and usually have mold and mildew fighting ingredients. They’re simple to use, just read the label.
Homemade cleaning mixture
Create your own mixture with:
- 1 gallon water
- 1/3 cup laundry detergent
- 2/3 cup of all-purpose cleaner
- 1 quart house bleach (in case of mold or algae)
Wear gloves at all times and first test your concoction on a small, out-of-sight area before committing.
Preparing Your House Prior to Power Washing
You wouldn’t want to destroy your house in the course of cleaning it, would you? So just take a minute or so to prepare:
- Close all windows and doors tightly.
- Switch off the power to all outdoor electrical outlets and cap them.
- Take away or cover up furniture, decorations, and plants along the walls.
- If your house has vents or gaps, seal them with plastic to avoid water penetration.
How to Power Wash Vinyl Siding – Step by Step
Step 1: Select the Proper Nozzle
Use a 25-degree or 40-degree nozzle. These give a wider, softer spray that won’t hurt your siding. Don’t use the red 0-degree nozzle, it’s way too strong and will gouge surfaces.
Step 2: Apply the Cleaning Solution
Most pressure washers come equipped with a detergent tank. Fill it with your cleaner of choice and turn the washer to the soap setting. Begin to apply the cleaner from the bottom up to avoid streaking.
Let it rest for 5–10 minutes but do not allow it to dry out. If it does begin to dry out, mist it with water.
Step 3: Scrub Tough Spots (If Necessary)
Have stubborn spots or mold spots? With a soft-bristled brush or sponge, give those spots an extra good once-over.
Step 4: Rinse from Top to Bottom
Now rinse time. Change to clean water mode and move from the top down. Hold the spray direction slightly below level to avoid letting water seep behind the siding. Use overlapping strokes to get full coverage.
Step 5: Inspect Your Work
Walk through your house and identify any areas that were missed. It’s simpler to reclean when the area is still wet. If needed, make another pass through on dirty spots.
Power Washing Tips for Best Results
- Keep 3–5 feet back from the wall.
- Maintain the spray in constant motion never stop in one location.
- Don’t spray directly at seams or upwards.
- Start with a test patch on an out-of-sight location.
Mistakes to Avoid
Too Much Pressure
More pressure is not necessarily better. Excessive pressure may warp siding, push water behind the panels, or actually loosen them. Use 1300–1600 PSI only on vinyl siding.
Incorrect Spray Angle
Never spray up at any cost. This pushes water under the siding, which may cause mold, rot, and damage inside.
Omitting the Rinse
Even when your siding appears clean once you’ve applied the detergent, you have to rinse. Soap residue will streak and draw more dirt in the long run.
How Frequently Should You Power Wash Your Vinyl Siding?
Twice a year is best for most houses. If you’re in a humid or wooded area, you may want to clean twice yearly. Regular cleaning schedules avoid buildup and make each job a breeze.
