Can You Power Wash Aluminum Siding?

You can indeed power wash aluminum siding, but you'll have to be very careful about it. If you've never power washed anything before, you will want to be especially careful. The thing about power washing aluminum siding is that a power washer is a very powerful machine.

It is able to spray water at a high intensity. If you're not careful, you could easily end up tearing up the grass and plants around your house with the power of the water. Besides that, you might even end up damaging the aluminum siding itself.

How might that be, you might ask? Even though aluminum siding is quite sturdy and indeed made of metal, water from a power washer could still end up causing damage. This is especially true if you choose a heavy-duty power washer instead of an ordinary one.

In particular, a powerful power washer could end up denting the aluminum siding. Once the siding becomes dented, it will be very difficult, if not impossible, to fix it. Usually, you would have to have that entire piece of siding replaced as a result which can be very expensive.

The Details

Besides denting the siding, the power washer might end up tearing the paint off of your house's exterior. This is especially true if the paint on the siding is already old and flaky, but newly painted siding may even be susceptible. Whatever the case, you can avoid all of these problems as long as you use the power washer in the correct fashion.

You will have to be at the right distance away from the siding. You will also need to make sure the power washer is on the right setting. Finally, you will need to make sure that your house's siding has already been prepared to be power washed.

Only then will you be ready to start power washing aluminum siding. But before you get out the power washer, where should you start?

Start by Washing Your Siding as Usual

Power and soft washing aluminum siding will not be the first step of the cleaning process. After all, a power washer can't do anything. It is best for washing off large swaths of dirt and grime but it is usually not the best tool when it comes to the details.

Before you use the power washer, you will want to have some simpler tools on hand. In particular, you will want to have a sturdy brush, some soap or other cleaning solution, and a garden hose. If you don't have a cleaning brush, a sturdy cleaning rag will do to take its place.

You will first want to spray down a large section of your siding with the garden hose. This won't do much to take off some of the debris stuck to the siding, but it will help to soften whatever is on the siding. This is especially true for any pollen or mildew that might have attached to the aluminum siding at some point.

Once you spray down your house, you will want to work relatively fast, otherwise, the water will start to evaporate and you'll have to spray the siding again. After all the siding is wet, you'll want to apply a cleaning solution. You have options when it comes to the cleaning solution you choose.

You could make your own solution out of soap and water. Or, for a deeper clean, you could buy some special cleaning solution at the store. Whatever the case, apply plenty of this solution across the section of siding you plan on cleaning.

Cleaning the Siding

Let the solution sit for a while. Letting it sit will let the chemicals in the solution break down the dirt that has gotten ingrained into the aluminum siding. As the solution does this, it will make it much easier to remove the dirt and grime later on.

After a few minutes, take your cleaning brush or rag and start to scrub the siding. A good brush with firm bristles will be able to clean the siding very deeply and remove whatever dirt may have been left on the siding. As you start scrubbing, you will notice that your siding will start to look cleaner and brighter already.

However, scrubbing won't be able to get rid of everything. After enough scrubbing, you will find that there are still some stubborn sections of dirt that may not want to come off. That's where the power washer comes in to save the day.

How to Power Wash Aluminum Siding the Right Way

Before you start power washing siding, you will want to make sure the land around your house is protected. If you have some plants or grass that you care about around the base of your house, cover them with plastic wrap. This will ensure that the power washer won't tear up the vegetation.

If you are careful with the power washer, you might not have to do this at all. However, it is better to be safe than sorry. Once that is done, you can bring out the power washer.

Remember that you shouldn't be too close to your house. Otherwise, the power of the water might end up damaging your siding. Instead, stand a few yards away.

How to Power Wash

The water should hit the siding with enough pressure to clean any remaining dirt from it, but it should not damage the paint or the siding itself. When you start power washing, you will want to choose a small section to work with. While it may seem like a better idea to clean a large section all at once, this isn't a good idea.

That's because you won't be able to get as detailed of a clean if you work on a large section. When you start power washing, be sure to start from the top of the section and work down. That way, any dirt on the siding will flow down to the ground.

Try to move the jet of water in one direction instead of going in circles or other directions. This will help ensure that the siding gets an even clean and that the dirt and grime don't get everywhere. After you clean the siding, let it dry.

Then, examine the result. If the siding still has some dirt, you might have to repeat the previous steps to get it completely clean.

Hire a Professional

If you don't think you're up to the task of power washing your own aluminum siding, hiring a power washing professional is your next best choice. Power washing your own siding can be stressful and time-consuming. This is especially true if you have a busy schedule to deal with.

You also might end up damaging your siding if you've never power washed anything before. That, of course, is the last thing you want for your siding. While a professional might cost you a bit extra, you will find that the cost is worth it.

A professional will be able to take a huge weight off your shoulders. The professionals can do all the work while you can direct your attention towards other duties. Once the professionals are done, your siding will look as good as new.
