How to Make DIY Pressure Washer Detergent

The easy way to cut down your pressure washer detergent expense is to make your own detergent at home. Here I will share three methods of making eco-friendly pressure washing chemicals for different surfaces.

If you want to make a solution for cleaning a concrete surface, put 1 gallon of water in a bucket. Next, add ½ cup of Borax, ½ cup of washing soda, and 1 tablespoon liquid dishwashing soap. Stir them well before you apply on a surface.

To clean your car or other vehicles, you should follow this recipe. Put 1 gallon of water in a bucket and add 12 tablespoons of laundry detergent powder. Mix it properly before you apply it to your vehicle.

This recipe will be applicable for any vinyl siding, such as your fence, wooden floor, and wall, etc. For this solution, you will need 1 gallon of hot water, 1/3 cup of TSP (Trisodium Phosphate), and 1/3 cup of laundry detergent powder. Apply this mixture on your vinyl surface and clean it.

The above methods are purely homemade pressure washer detergent that will not only save your money but also they are friendly to the environment.

Why you can’t use regular soaps in pressure washers

A pressure washing machine is designed to remove dirt using the water force, and they need a special type of soap. Soap that is strong enough to weaken the dirt, mud, grime, or grease is generally used with this machine. The detergent that you use to wash your clothes doesn’t have the strength to weaken the dirt on a surface unless you rub it properly. This is the same case with your dishwashing or other cleaning soap; they need rubbing to make things clean.

Generally, vinegar, citric acid, oxalic acid, bleach, sodium hydrochloride, ammonia, potassium hydroxide, and sodium hydroxide are used in the solution of a pressure washer soap. These chemicals easily break down the strong combination of dirt, mud, grease, etc. Once they become weak enough, the water force of your pressure washer easily removes them from a surface. This is the reason your machine needs a special type of pressure washer cleaning solutions.

How Do I Use the Detergent?

Just because you don’t know how to use a pressure washer detergent properly, you might get a poor cleaning performance by your machine. You must know how to use detergent with pressure washer properly to get the best result. This definitely is not rocket science, so you need not worry much. You just have to follow a few instructions, and that’s it.

Most of the cleaning solutions available in the market are highly concentrated and are ready to use right out of the box. They need to dilute properly with water, and the solution you are going to use will tell you how much water to add. Put the mixture into your onboard detergent tank and turn on the switch. You can use the mixture from a bucket as well if you don’t have a detergent tank. When you apply soap, you must use a low-pressure nozzle.

While applying on a surface, you must move your spray gun slowly so that the soap is applied evenly on a surface. You can also use a rotating nozzle for rubbing purposes. On the vertical surfaces, move your spray gun from bottom to up to avoid streaks. After you finish applying your detergent, wait for few minutes for the solution to do its work.

After you applied soap, you need to use a high-pressure nozzle for cleaning. On a flat surface, move your gun from one side to the other, and on a vertical surface, move it from top to bottom to avoid streaks. Cleaning solutions are bio-degradable, so you must apply plenty of clean water for a better result. Don’t forget to get the solution out of your machine properly by using plenty of water.
