When pressure washing your car, patio, or your house, you need to have a soap or detergent ready. After a while, thick debris or dirt may stick to your home’s walls or your car doors. While a pressure washer has the power to loosen the dirt, it may take more than just water to fully wash the dirt away.

How To Choose The Best Pressure Washer Soap For Different Cleaning Applications

Now that you know our top picks for best pressure washer house cleaners, let’s move onto something a little deeper. Even if you know what products you should look out for, picking the best one for your situation is another story.

You see, each soap type has its own use. So, the best pressure washer soap for cars may not necessarily be the best pressure washer soap for house nor is it the best pressure washer soap for brick material.

With that in mind, we believe that you must know how to pick your pressure washer cleaning agents through a concrete list of criteria.

If you don’t have one in mind yet, we’ll give you a list that you can use:

  • Purpose

The first thing that you need to take into consideration is the purpose of the soap. As we’ve reiterated above, you need to buy soap depending on the purpose of application. For instance, if you want to wash your windows, you need to get something that can polish windows.

So far, the best pressure washer soap for windows is the vinegar or ammonia-based soaps. If you want to clean your vinyl sidings, the best pressure washer soap for vinyl siding will probably be the Sodium based types like sodium hydroxide or sodium hypochlorite.

In any case, take a look at the ingredients of the soap and the list of applications it can clean. Usually, you’ll find the applications of the soap on the front package.

  • Safety

When we talk about safety, we refer to how safe the soap is on certain surfaces. Some soaps, especially the bleach-based ones, can damage some objects-- like the exterior of your car. As much as possible, we don’t recommend that you use strong soaps unless really needed. After all, bleach-based soaps are for heavy duty purposes anyway. For regular maintenance cleaning, you can stick with mild ingredients or better yet, natural ingredients.

Another aspect of safety that we need to take into consideration is health related safety. Some soaps may not be good for your pets, children, or family members when inhaled. Some may also be harmful to the skin upon contact. While the milder soaps won’t give you any problems, stronger ones might.

So, if you know you’re going to use a strong soap, prepare the necessary equipment. You’ll need long sleeves, long pants, and a mask. Also, make sure to keep your children and pets away from the vicinity while you use strong soaps.

  • Environmental Impact

It’s no surprise that chemicals can damage the environment when they get into our drains. Unfortunately, most soaps are made out of chemical ingredients that may cause a negative environmental impact. This shouldn’t be a problem if you’re only using a little bit for your cleaning. But if you need to clean your house, you’re going to need more than just a little.

As much as possible, we recommend that you get the soaps that use natural ingredients. Try to get the ones that don’t have ammonia or bleach. Only use the strong, commercial grade soaps if you absolutely have to.

  • Versatility

While most soaps have their own specialties when it comes to application, there are some that are more versatile than others. This means that there are soaps that have more applications. There may be some soaps that specialize in cleaning cars, vinyl siding and brick material all at the same time. As a general rule, we prefer the soaps that have high versatility because it allows us to save money and storage space. That’s why most of the products we picked are multi-purpose ones.

  • Size

The last thing that you need to consider is the size. This refers to the size of the soap container. The size will determine how much soap you can use at a given time. The bigger the size, the more soap you can store and use. The average size for a soap container is around 1 gallon. However, they may come in smaller sizes such as a quart. Just pick the size based on how much you want to use.
