Things to Consider Before Buying Pressure Washer Soap
Give your ride some love by using high-quality soap. You don’t want to have streaks and scratches ruin a nice paint job. So, after you’ve picked a good foam canon, the next thing you want is to choose soap while keeping a few things in mind.
An effective car wash soap gives off lots of suds. It indicates that the soap is highly capable of removing road grime, grease, and dirt. This is because it lifts dirt particles off the surface of a vehicle. What’s more, lots of bubbles soak up dirt, so you don’t have to scrub the car’s body. It reduces the chance of scratching the car’s surface during cleaning.
That’s why you’ll want to note the foaming capacity of the soap you have in mind.
Concentrated Or Pre-Diluted Formula
You’ll find concentrated and diluted formulas for use in a pressure washer. Concentrated formulas need diluting in a separate bucket. They are a bit handful but are on the budget-friendly side. One bottle will sustain your vehicle through several washes.
Diluted formulas, on the other hand, come in spray bottles. Some can be attached directly to the pressure washer hose. They are convenient because they are pick-and-go and you don’t need a foam cannon. The only disadvantage is that they are costlier than their concentrated counterparts.
Some brands include additives like wax to protect the car’s surface between washes. The wax bonds with the car’s outer coating so it can stay on the car’s surface long after washing the vehicle.
However, cleaners with additives are not ideal for concrete driveways, house siding, decks, and outdoor furniture.
Are you concerned about harming your landscape plants?
You will want to consider a biodegradable pressure washer soap. Fortunately, many brands are now biodegradable. The best soaps are EPA-endorsed. It means they won’t harm waterways and animals. But to be safe, always look at the label. There should be a safety status. If not, you can contact the manufacturer or look up the ingredients on the MSDS.
Yeah, we know it’s a car wash cleaner. But did you know that some soaps are too intense that they irritate drivers? As a result, you’ll want a cleaner that has a pleasant scent for you. So, if you like citrus, pineapple, or lemon, go for it.

Frequently Asked Questions (FAQs)
1. Do pressure washers need special soap?
Pressure washers need special soap. Unlike dish soap, pressure washer soap can withstand the high pressure and power of these machines. Such soap can work at different velocities and pressure of the pressure washer unit.
So, to ensure that you get the most out of a pressure washer, it’s best to use it together with dedicated pressure washer soap.
2. Can you use car shampoo in a pressure washer?
Car shampoos are incompatible with pressure washers. They are for manual applications. As a result, you won’t get as many suds as you’d want in a pressure washer. To this end, you’ll use too much of it to get rid of stubborn grease. So, it can cost you more than getting a good pressure washer cleaner.
