What’s The Best Engine Degreaser For A Pressure Washer?


Bear in mind that one degreaser may not provide all possible benefits to its users. However, some engine degreasers have quality features and specifications, allowing them to outperform other options on the market. Some of these ideal choices are:

1. 3D Orange Degreaser

Many harsh chemical cleaners can help degrease pressure washers and other machines, but they can also promote risks. On the other hand, organic cleaners like this orange degreaser from 3D can help remove gunk buildup without those dangers.

Users report that this solution is a powerful grease remover. It doesn’t even emit a harmful chemical smell. However, new users might commit a mistake in diluting this product since the label doesn’t show the correct mixing ratio.

2. Oil Eater Cleaner Degreaser

This degreaser is a powerful solution for removing different unclean substances, including dirt and oil. It's also usable on different washable surfaces, such as engine bays and pressure washers.

Keep in mind that this product typically provides the best results it can provide if used on cold surfaces. So it may not be good to use this degreaser during a hot summer day.

However, the formula might be quite harsh for some delicate components. It’s best to perform a spot test before using the recommended amount to ensure you won’t bring harm to your pressure washer.

3. Method Heavy-Duty Degreaser

Ease-of-use is perhaps this surface degreaser’s best trait. It comes in a bottle with a built-in spray nozzle cap. That way, you would not need to worry about transferring the contents to another container, unlike other formulas on the market.

The formula is also reasonably safe to use without the need for rubber gloves. Some users said they didn’t experience any side effects when using the product barehanded.

4. Dawn Professional Heavy-Duty Degreaser

The price of this strong degreaser might put off some interested purchasers, particularly those on tight budgets. But the amount of degreaser you’re going to get from this product is generally more than you’d receive from other options intended for home use.

With this cleaning agent, you can deal with tough grease and gunk from different materials and surfaces, including those in commercial environments. But it might be wise to transfer the contents of this product to another container with stronger build quality. It's because some customers mentioned that the container could puncture easily, causing leaks.

What Makes A Good Degreaser For Pressure Washer?

Apart from the products listed in the previous section, you can find other great engine degreasers for your pressure washer on the market. But take note that finding a capable degreaser for motors often requires you to think about certain factors. Some of the things to dwell on are:

Material Compatibility

Pressure washers use different materials, such as rubber, steel, and plastic. So a harsh degreaser could put unwanted harm to some of these elements, causing the machine to malfunction or even break.

Select a degreaser with sufficient gunk-removing prowess but can still maintain the integrity of the different pressure washer materials. If you’re unsure about the product’s potency, do a spot check before using the rest of the cleaning solution.


Some engine degreasers have synthetic ingredients that might not be eco-friendly. For example, certain degreasing agents use volatile organic compounds (VOCs), which can promote greenhouse gas effects when exposed to the environment.


Think about purchasing and using a pressure washer degreaser with high dielectric strength. This property denotes the electric field limit that the product can generate to break grease and other gunk down. That means that a degreaser with low dielectric strength may not offer satisfactory results.

Chemical degreasers may also have flammable compounds that become hazardous when used in or around high-temperature areas. Ensure that the area doesn’t have catalysts that may spark fires when you’re using these options. Otherwise, choose a non-flammable degreaser, although it might be more expensive than an option with combustible elements.


Certain engine degreaser brands established their names in the cleaning industry by providing excellent products and services to their customers. 3D Car Care, for example, provides quality degreasers and other cleaning solutions to customers located in over 50 countries around the globe.

Another cleaning product company to look into is Method. It focuses its products and services to promote solutions for both social and environmental issues. The business also considers taking care of the environment with each product manufactured by meeting eco-friendly standards.

First, check your cleaning product’s guidelines and instructions. Different products, such as certain degreasers, often require users to perform the correct applications using the right mixtures.

For example, a particular cleaning solution might require you to use the product at full strength if you’re cleaning a pressure washer motor. On the other hand, you need to dilute one part of the same product with three parts of water to remove dirt and grease buildup from car carpets and floor mats.
