Buying Guide

When you are in search of the best cleaner for vinyl siding pressure washing, there are some things that you will need to consider. Here is what you should look out for;

Consider The Type of Cleaner: Soap or Detergent

Before you choose any of them, it is important to understand them individually. No need to Google for their difference because that’s our job for you today. Here is a look at the difference between a soap and a detergent;


Soaps are regular cleaning products that are made from natural ingredients such as plant oils and animal fat. The blend of these raw products and salt will be processed to fatty acids and glycerin with steam. After that, the soap will be produced. The bar soaps use sodium as salt, while liquid soaps use potassium, like salt.

Soap will then be mixed with water, which will then break it down to dissolve grime, dirt, and stains with ease. However, one drawback of soaps is that the minerals in them will react with the minerals in the water. As a result, you will be left with an insoluble film.


On the other hand, a detergent uses chemicals and other inorganic ingredients instead of natural ingredients. Mostly, detergents are used to clean clothes and get rid of tough stains. It is important to keep in mind that the detergents will come with different sensitiveness to soft and hard water. This will be with regard to the chemical composition.

So, if you are looking for the best cleaner for your vinyl siding, we recommend that you go with a detergent. But, this would be the best pick if you are using hard water to clean your siding. Also detergents have a better cleansing action than soap.

Consider the Ingredients

The ingredients of the cleaner is another thing you should consider. This will let you know if you are using one that is safe enough for your plants, landscaping or the pets around. Some of the common ingredients found in power washer cleaners include the following;

Citric acid: This is ideal for cleaning the hard surfaces such as a wood deck, driveway, and concrete. Also, this ingredient is used for removing stains on the mentioned surfaces.

Vinegar: Most people already know that vinegar is a common cleaning home remedy. It is usually used to clean windows, countertops, as well as corners of the building. You can use it for surface polishing and shining.

Oxalic acid: This ingredient is used to remove any rust or corrosion. It can also be used for any other cleaning.

Ammonia:This is a general glass cleaner, and it is also used for cleaning stainless steel.

Sodium hydroxide:This one is also known as caustic, and it will dissolve fats, grease, or other grime with ease. Furthermore, it is known to lift off dirt, grime, and stain easily hence making it easy to clean your siding.

Ideally, choose a cleaner that comes with Sodium hydroxide, which will easily lift off the dirt and grime without using chemicals.

Bleach: This is a blend of sodium hydroxide and sodium hypochlorite. It is a strong sanitizer and disinfectant that helps to eliminate stains and stubborn dirt on surfaces.

If you have mildew and mold on your vinyl siding and other areas outside your home, you should consider a cleaner with ammonium chloride, oxygenated bleach, or chlorine bleach.

Above all, avoid cleaners that have organic solvents and petroleum ethers line THF, acetone, or benzene. These ingredients can cause haziness, discoloration, and can even damage your vinyl siding in the long run.

Cleaning Method

So yes, a pressure washer will only need you to spray at the vinyl siding to remove the dirt. However, not all of them won’t require scrubbing and rinsing. Some cleaners will need you to add some elbow grease for you to eliminate the dirt and grime accordingly.

For that, ensure that you check and possibly test if the cleaner will get rid of the dirt and grime on your siding without the need for scrubbing or rinsing. However, it doesn’t mean that one that will require you to scrub and rinse is not effective. It’s only that the one that needs no scrubbing or rinsing is time-saving. However, some might not get rid of the stubborn stains effectively.

Since you will be using the cleaner with your pressure washer, it is recommended to choose one that doesn’t require scrubbing. It should contain powerful ingredients that will make it work perfectly with the power of the pressure washer to wash off the typical stain and dirt on your vinyl siding.


Okay, this is not such a major point to focus on, but it still should be considered. The size or capacity of the cleaner will determine if it will cover the outdoor areas accordingly or not. Generally, a cleaner in a large container will serve you for a long time, and it tends to be more reliable if you have a large home. Choose the size based on the size of your home, how often you intend to use it, and the mixing ratio to water.

Ideally, choose a 5-gallon cleaner as it tends to save you money while serving you for a long time.


We also consider the smell of the cleaner when shopping for one. Regardless of how clean your vinyl will look, it is important to consider the smell that is left behind. This will depend on the preference of the homeowner.

The smell of snow foam, for example, can leave your vinyl smelling nice and cool, which is also a neutral smell. All in all, ensure that you choose a product with a smell that works for you perfectly.

Don’t forget to choose a cleaner that is safe for your garden. In other words, choose an eco-friendly cleaner at all times.

Above all, choose one from a reputable brand to be sure of getting the right stuff for your siding clean up.
