Years ago, when I had my first pressure washer I used my laundry detergent. Can’t believe I did that.
This is why you should not do such a dumb thing:
- It will not work quite well and make you disappointed
- You are going to put hard work cleaning the stains by a scrubber
- Ultimately you will return the pressure washer
Let’s make things clear for a great wash, right now.
Imagine the greasy stains on your dishes. How do you wash them? Using only water will give you the minimum result. The trick is to use a dishwasher.
The same thing applies to pressure washers. A combination of hot water and detergent is a killer combination of pressure washing those tough stains!
To speed up the cleaning process dramatically according to science, hot water is the best option for removing those grime and oils.
So using pressure washer detergent, soap, and other cleaning solutions will give you an edge over the tough stains with a pressure washer.
There are not many pressure washer soaps, detergent available in the market so it is recommended to use concentrated detergent for the best result. Or you can also think about preparing homemade.

Ultimate 7 tips for final detergent selection
The difference between pressure washer soap and pressure washer detergent
- Soaps and detergents are very similar in chemical properties still they a major difference. Soaps are formed by natural products like starting with fats and oils which are obtained from plants or animals. These are combined with high-pressure steam while producing fatty acid and glycerin. Combining the fatty acid with salt produces soap.
- Sodium soaps are converted into bar soaps and potassium salt is used for liquid soap.
- Soap breaks down when mixed with water or oil due to its hydrophilic and hydrophobic ends
- Detergents are produced from man-made chemicals
- Soaps are used for skins and detergents are used for clothes
When to use soap and when to use power washer detergent?
Soaps are biodegradable and do not possess a threat to the environment. But soap mixes with sodium and magnesium in hard water to create an insoluble mud type residue. This white residue can stick to your surface.
On the other hand, the detergent does not have this problem. The special benefit of detergent is that it is engineered for different cleaning surfaces.
The most effective solution is to combine the soap and detergent together.
How does a pressure washer detergent, nozzle and injector work?
This is a very interesting process! The proper blending of soap or detergent with the power washer water flow is very important. This introduction of detergent can be done in two ways. Before entering the pump (upstream) or after leaving the pump (Downstream).
Downstream pumping systems provide multiple options. This downstream injection system is equipped with a nozzle with a variable pressure adjustment capacity. A venturi injector is used for making a pressure differential which will draw the pressure washer detergent from the container into the system.
In the upstream delivery system, a float system is necessary to produce zero pressure which delivers the chemical into the system. So the downstream system allows more option for chemical delivery.
Is pressure washer soap, detergent or other chemical solution safe for your environment?
Pressure washer detergent and other chemical solutions must be environment-friendly as the chemicals mix with the ground which will mix with rainwater underground. So be sure to check the label if it is biodegradable.
Cleaning is good but you need to take off your environment too!
Difference between Residential and Industrial pressure washer soap, detergent and other chemical solutions and which one to use?
The math is simple. Industrial things like pressure washer car soap come in large barrels. Industrial pressure washer detergent is supplied in concentrated condition. And the residential grade comes in pre-mixed condition.
If you pressure wash around your home a few times a month then you should go for the residential pressure wash soap or chemicals. Buying a residential pressure washer detergent like vinyl siding cleaner will cost you some extra bucks per gallon. At least you do not have to worry about diluting the concentrated chemicals.
And finally, if you pressure wash for living the industrial range is for you. Why? It comes in a large barrel and concentrated. Just use when you need it. This will save you some money.
What kind of soap to use in pressure washer [Foam or no foam?]
If you love to play with foam then choose carefully. Let’s discuss here. First, read the label on the pressure washer detergent bottle. Some of them can cause little foam. If you want less foam its good! On the other hand, if you want more foam then using foam cannon might be a good idea.
Using a foam fun party to wash your car is a great idea!
Your detergent might not be able to provide you with a foam fiesta you are looking for. You know what? I love the view of a car covered with foam.
There are some pressure washer soaps available on the market. A foam cannon combining with a pressure washer is a great combination.
You may consider my opinion. Less foam for your driveway and more foam for your cars!

Prepare Homemade Pressure Washer Detergent
Thinking about an eco-friendly pressure washer detergent is excellent. Although, you may not get the same result as you will get with a chemical detergent, yet let’s try this.
This requires some crazy simple ingredient for preparing a homemade detergent that works. Mix 2/3 cup of household cleanser powdered with 1/3 cup of phosphate-free laundry soap. Mix these with a gallon of water.
The mixing has to be proper for a good result. Pour this solution in the pressure washer detergent tank and start cleaning.
You may have to use this process more than once to get a good result. Mildew buildup can be a challenge for this detergent to overcome. To get over this you can use vinegar on mildew.
This is helpful for plants, keeping them away from chemical detergents.
Before I Let You Go
Using some good detergent with a pressure washer is a solid way of getting a good result.
And you can also try making something of your own at home. This might not be as powerful as the chemical ones.
I suggest not to use hot water unless you have an industrial pressure washer. Pressure washer detergent or soap is excellent for removing grimes.
