How to Clean Exterior Siding with a Pressure Washer

Step 1.

How to Clean Exterior Siding with a Pressure Washer

First, understand that different types of exterior siding require different detergents, so use the special solutions as per instructions. Before embarking on a cleaning spree, first repair any damaged siding. This is regardless of whether it is vinyl, aluminum, fiber cement, wood, stucco or brick and stone siding. It is wiser not to wash lead paint. Consider using an extension wand or lance to make your pressure washing easier and keep you off of the ladder. If you do use a ladder, remember: pressure that is exerted when you pull the trigger can be enough to topple a ladder!

Step 2.

Before starting, make sure to shut of the electricity to open outlets and cover light fittings if applicable. Don’t forget to close all of your windows and doors. You don’t want the inside of your home looking like tornado struck it! Don’t forget to protect your eyes and you’re ready to go.

Step 3.

Attach the hose to the machine and start it up. Get a siphon into the soap solution and fix on the soaping nozzle. You can also save a lot of time working by using a turbo foamer attachment. This attachment will work much better to distribute chemicals and can easily reach the second or 3rd floor of a home. Work your way up starting at the bottom for this will prevent the soapy solution from running down the siding. Apply the detergent to one side of the home and allow 5-10 minutes to elapse before washing it down to clean away all the grime and dust. Only use solvents that are approved for pressure washer use – other solvents could damage your pressure washer, and may not be environmentally safe.

Step 4.

Change the pressure washer nozzle to the 25-degree nozzle or 40-degree nozzle to rinse off your siding. Maintain a distance of at least 1 foot away, and commence washing from the top working your way to the bottom. Remember that the lance or wand must be held in a direction that’s perpendicular to the siding. Once you’re done with one side of the house, move to the other side and repeat the process. In just a few hours you will have beautifully clean exterior siding.

How to Clean Exterior Siding with a Pressure Washer

A few words of caution—when you’re washing aluminum siding don’t spray up under the panel overlaps. For wood siding, be sure to wet the surface before applying the detergent. Treat brick siding with a light spray to ensure that no detergent buries itself deep in the brick.

Clean exterior siding not only looks good but will protect the vinyl siding on your house for years to come.

    Thanks for writing. Cleaning your home’s siding every year and keeping it in good repair extends the life of any siding and heads off replacement costs.

    I clean my vinyl siding every year with a mix of one third each,water,bleach and mean green. I use a pump sprayer to put it on. I let it stay on for about ten minutes and rinse off with a garden hose.Looks like new.

    I really like your tip about using an extension wand or lance to assist with pressure washing the siding of the home. My husband loves using the ladder when he’s doing the washing but I don’t so I will have to look into the extension wand. I will be sharing these pressure washing tips with my husband.

    I highly recommend an extension wand. If you have to use a ladder, it’s best to have two people doing the washing, one to wash and one to help move around the hose and cords. A wand will make light work of it and save you from climbing up and down a ladder, which gets tiresome fast!

    I am happy to have found this article about how to clean siding with a pressure washer. I did not realize that first, one must attach the hose to the machine and then, start it up. It would also be good to have a good soap solution. If this task seems to complicated or difficult, it would be a good idea to seek professional help to ensure quality work in an efficient amount of time.

    I’m glad you reminded me to shut off the power to the external outlets. Getting the exterior of the house clean is important, but it’s also important to avoid any potential issues that may come up from not turning off the outlets. It would help me to double check that the exterior is safe to pressure wash before I begin the project.

    Good tips for cleaning siding with a pressure washer. The one I have not yet seen posted before is wetting the surface before adding detergent, but it is a very smart thing to do. Keep on leading the way towards educating the masses, my friend!

    I would love to get all of my siding cleaned off. I think that is the advantage of having vinyl siding. It has been really durable. I think the best thing is that the siding is able to be cleaned.

    My husband wants to get a pressure washer to use on the outside of our house. Thanks for the advice about how different types of siding require different detergents. Another thing to consider is using the correct pressure setting for the area you are cleaning.

      Hi Sarah! You’re absolutely right, using the right amount of power is VERY important to ensure you’re getting things clean without doing any damage. Keep on eye on our blog, we have a couple of post on the way that address exactly that.

    Are there any advantages to letting detergent set on a surface longer before rinsing? 5-10 minutes seems short compared to what I have seen on other sites.

      Hey Gary, awesome question!

      Letting the correct chemicals sit on a surface does have it’s advantages. The chemicals will break down the bond the dirt has on the surface it is attached to. Usually 5 to 10 minutes is plenty, you want to rinse it off before the chemical starts to dry.

      We also suggest that you test, test, test before applying any chemical to a project. Apply cleaner, wash and completely dry a small area of your project, so you know exactly how things will look when completed.
