The Best Homemade Vinyl Siding Cleaner with a Pressure Washer

Cleaning your vinyl siding with a pressure washer can be a daunting task. But it doesn’t have to be! We will show you how to clean your vinyl siding quickly and easily using a pressure washer. We will also provide you with some recipes for a homemade vinyl siding cleaning solution that will get the job done right. Let’s get started!

Set Up Yourself and Your Space

First, you need to prepare yourself and the location where you’ll be working.

Make sure to wear clothes that you don’t mind getting dirty and closed-toe shoes. You’ll need protective clothing due to potentially abrasive chemicals.

You’ll also want to clear the area around your home of any obstacles, including lawn furniture, hoses, and kids’ toys. This will give you a clear area to work in and prevent any accidents.

Put tarps over plants you don’t want to get chemicals on and cover your air conditioner unit if it’s located near where you’ll be working.

Now you’re ready to start!

How to Pressure Wash Vinyl Siding

You will need a pressure washer and a vinyl siding brush attachment. You will also need a garden hose and a bucket. Fill the bucket with water and mix in your desired cleaning solution. Then, attach the garden hose to the pressure washer. Next, turn on the water at the spigot and let the pressure washer fill up with water.

Now you are ready to start cleaning! Begin at the bottom of your vinyl siding and work your way up. Be sure the pressure washer is pointed straight so that the water doesn’t go behind the siding. If you don’t have a vinyl siding brush attachment, you can also use a soft cloth and apply the cleaning solution by hand.

Once you have finished cleaning the vinyl siding, wash the siding with clean water from a garden hose. Be sure to remove all traces of cleaner before allowing the area to dry.

And that’s it! You’ve successfully cleaned your vinyl siding with a pressure washer.
