It’s also safe to use, and has a non-toxic formula. No wonder it’s the top of the list, right?

So diving into the capacity, this model naturally requires to be diluted as well before use. And doing that, you’ll easily be able to cover about 6400 square foot, which I think is more than enough for what you’re getting.

This detergent comes in two packages. You can either get it in one gallon or get the 32 oz. spray with a one gallon refill!

Tried and tested, this model is professional grade and is a non-corrosive mixture that’s well suited for use on vehicles and in controlled environments!

What’s best about this is this makes the Pro HD quite versatile, and arguably the best choice to with if you’re looking to clean industrial equipment or even recreational vehicles!

The only downside to this model is that the dilution bit isn’t simple, and you’ll need to pay a little attention to detail. I mean, this model is heavy-duty and it’s fair to say its super concentrated.

What else could you ask for?

On top of all of this, the Karcher also has a faint nice odor. It’s not really a plus to the package, but I still think it’s a neat addition to have.

Now talking about the downsides, I don’t really think there’s anything you need to be worried about. All in all, I think the Karcher Car Wash & Wax Soap is the best choice for detergents if you want something for your car. Go for it!

4. Karcher Multi-Purpose Cleaning Pressure Power Washer Detergent Soap (budget-friendly choice)

Karcher Multi-Purpose Cleaning Pressure Power Washer Detergent Soap

The Karcher presents a multitude of benefits if you choose to go with this model. But that’s not the reason it’s on this list!

The main reason why I feel that this model deserves a shout out is that for the performance that it offers, it’s easily one of the most budget friendly choices there is. So if you’re looking for a solid detergent that doesn’t break the bank, then this is it.

As far as cleaning and performance goes, the Karcher doesn’t really lack behind any other model in the higher price brackets.

It combines a good formula with the right constituents to give you the multi-purpose clean that you’re after. That’s a definite win in my books!

Another good thing about this model is that it’s highly concentrated as well, and can allow you to make up to 20 gallons of solution in one go. So with that said, if you’re looking to clean the driveway, stone, or anything of that sort, you’re practically set for the long run.

As far as downsides or anything are concerned, there isn’t really much that the Karcher leaves behind. Just make sure to dilute it as needed because that’s how you’ll be getting the best bang for your buck!

5. Simple Green Concrete/Driveway Pressure Washer (Best for your driveway)

So if that’s what you’re looking for, then the Simple Green Pressure washer cleaner is the best choice to go with.

This model works best with concrete surfaces and other rough patches that are often hard to clean. Once loaded up, your pressure washer and this liquid will make sure to give you the performance you’re after and get rid of that dirt that just won’t go away!

Another good thing about this model is that it’s also non-corrosive or bad for the environment. This model works fairly easy, and won’t really damage the plants or the soil if it leaks into the ground. I call that a win, since it makes the cleanup so much easier!

However, there’s one little thing to keep in mind. If you feel that this soap doesn’t do its job in one go, there’s no harm in round two. Rest assured, you’ll get the effect you’re after. Just stay persistent!


  • Does not hard flowers or trees
  • Deals with discoloration really well
  • Cleans evenly against all pollutants

6. Krud Kutter HS01 Green Pressure Washer Concentrate

Easy to use, handle, and work with, the Krud Kutter is a must-have brand if you’re looking for an effective way to take your pressure washing experience to the next level!

This model comes in a gallon pack, and is concentrated enough to get your job done, but that’s where one of its major flaw lay. But don’t worry, this is the only downside to it. The Krud Kutter has a low coverage of 2000 square feet only.

Compared to other models, this is a bit of a letdown and doesn’t really make this a prime choice.

But hey, on the bright side, you’ll be getting excellent cleaning in the area that is covered.

So moving on, this model has unique additives which allow it to deal with dirt, debris, and the usual, along with algae, fungus, mildew, and other pests that can make your surfaces dirty and filthy.

I think this is credited to the unique formulation that Krud Kutter is known for. On top of all of this, you can even remove oxidation and gray weathering on wood.

So at the end of the day, you’ll have access to one of those detergents that can seriously tackle all types of cleaning jobs out there. So what are you waiting on?


  • No petroleum solvents
  • Removes gray weathering easily

  • Good for use against algae as well


  • Doesn’t cover that much area

7. Simple Green 13005CT Industrial Cleaner and Degreaser

If you’ve been using Simple Green for some time now, then I’m sure you’re familiar with their traditional scent.

Taking it a step back to the classics, this is a great choice to go with that comes in a gallon package and has a pleasant sassafras scent.

So once you’re done cleaning, you’ll basically be striking two birds with one stone. A premium cleaning experience, and an odor that shows you’ve got work done.

But that’s not all!

One of the defining features of this model is that it is authorized by the USDA and can actually be used without any worry or hassle to the environment.

This is done to the point that Simple Green is actually employed for cleanups based in poultry and meat farms, and it’s safe to say if it can be used in that type of environment without any repercussions or damage to wildlife, you can definitely use it in your driveway!

I’d recommend this model for many reasons, among which the most popular one of course is that it cleans well without taking that much time. It’s also eco-friendly, non-toxic, non-abrasive, and simply one of the best models that Simple Green has released in a while!

  • None

8. Briggs & Stratton Multi-Purpose Cleaner and Concentrate

Coming in a blue shade, the Briggs & Stratton Multi-Purpose Cleaner and Concentrate is a pretty decent choice for cleaning and restoring your patio, siding, and virtually everything else!

This model is a versatile choice that’s fit for use if you’re looking for a general detergent or soap for your pressure washing need!

What I like the best about this model is that it’s very easy to use, isn’t that hard to get the hang of, and works like a charm every single time. The instruction for use come with the package, so if anything, this model has you covered from A to Z.

Another neat thing about this model is that it’s compatible with direct from concentrate soap system, and doesn’t really require any type of mixing either. So it’s entirely up to you if you want to work with the dilution or not!

I didn’t really find any type of downsides to this choice, so there’s nothing really that you need to worry about.

Since the dilution thing isn’t really necessary with this one, you can just start off as is and start getting work done. So with that said, this is definitely a good choice to go with if you’re digging the blue shade!


  • Can be used directly as well
  • Can give a solution mixture up to 16 gallons
  • Comes with instructions on how to dilute


  • None

9. Sun Joe Premium Car Wash Soap & Cleaner

Coming to our bottom half, the Sun Joe Premium Car Wash Soap & Cleaner is one of the unique models that you’ll find in the market this year.

This model comes in three major scents. You can either get it in pineapple, the orange-vanilla, or the coconut. All of them are equally good, although I’d say that the orange one is my favorite!

So let’s talk about functionality.

Well, the Sun Joe definitely has that covered with their biodegradable mixture. It removes dirt and grime, dust and everything you need to get rid of, while also being safe for the environment.

Not only that, the Sun Joe is also pretty versatile and can handle a wide assortment of surfaces such as brick and wood.

All in all, I think this is a fairly good choice and it works best if you have your pressure washer foam cannon attachment on. Once you’re there, say hello to deep and effective cleaning!

However, the foam that you’ll get isn’t that great. Sure, you’ll have deep cleaning and a scent that you won’t get with any other model, if anything I think that the foam production could have been better!


  • Comes in different scents as well
  • Versatile surface application
  • Biodegradable


  • Foam production not that good

10. AR ANNOVI REVERBERI ARCTW04 Pressure Washer Detergent

Last but not the least, the AR Annovi washer detergent is a feature that I think concludes this list best.

Coming in three different niche, this model will help you address all your pressure washing queries. You can either get the degreaser version, the deck and fence, or the car wash version.

With that said, it’s fair to say that this model helps clean well. This is because each type of AR detergent has a different mix which tackles the respective surface best.

But I think in a way, this is this model’s little drawback as well. You can’t really make big on versatility, and are sort of restricted to where you can freely use this model.

But don’t worry, let’s move on!

Like all models, you’ll need to dilute this model as well. Once done, feel free to apply this however and wherever, as long as you’re working with the right type of target material.

With that said, I think it’s important to mention that the general gist of all AR Annovi products is the same. It’s safe to use, good for the environment, isn’t toxic, and works like a charm.

So if you’re looking into this last feature, then I don’t think there should be anything to hold you back. It checks off all the major features that I think you should be after.


  • Works well for all vehicle surfaces
  • Can be used as a traditional soap as well
  • Makes up to 30 gallons!


  • Has different packs for different surfaces

Buyers guide

When it comes to choosing the right type of soap and detergent for your pressure washer, there are a handful of things that you’ll need to take care of.

By making sure that you pay attention to the details, you’re basically setting yourself up for success in the future. So keeping that in mind, here’s what you should consider when making your selection!


Starting off, the first thing that I think you should consider is the capacity being offered.

Generally, each brand and model comes in various capacities. The standard is often 1 gallon, but you can often get more than that, and rarely will you find a soap bottle less for that.

Now the reason why this is an important factor to consider is because knowing how often you’ll be using the detergent, and where exactly you’ll be using it, will give you a good idea of how much detergent you’ll be needing.

So save yourself the hassle of reordering, and make sure to get just the right amount you’re after!


If you’re a responsible citizen, then it’s natural to want to be and act sustainably wherever feasible.

Now for the most of us, we don’t really have the resources to follow through with the cleanup process. We can’t really dump the residual liquid or anything of that sort, and we don’t have an option to properly deal with that either.

So if you’re like me and have the same issue and concern, I would highly recommend going with a model that is environmentally friendly.

Eco-friendly detergents aren’t bad for the environment and don’t really have consequences that other life-forms have to suffer because of. Likewise, they’re also less toxic to deal with and are actually safer to use.

I’d personally recommend choosing an eco-friendly biodegradable choice. It’s the right thing to do!


Scent is often an underrated attribute that people don’t really consider when choosing the right type of detergent for their pressure washer.

While this feature is not entirely necessary, and you can make do without this without compromising the quality of the cleaning, I would still highly suggest that you consider the scent that your detergent comes with.

Why? Well, for starters, wouldn’t it be nice to actually have a scent-based proof that you’ve actually got cleaning done. Secondly, having a nice scent also means that you won’t have to worry about any other odors from dirt and debris when you’re done.


It goes without saying that different type of pressure washer soaps and detergents have different chemical constituents. And when it comes to making the right choice, it helps to know what your choice has in them!

For instance, oxalic acid as the main ingredient is a great choice if you’re looking to remove rust. Similarly, vinegar helps in the completing of bronze surfaces, doors, and windows.

Adding onto that, ammonia is often a main constituent for cleaning steel and glass, and sodium hydroxide is used for the removal of grease.

Lastly, if you’re looking to clean concrete surfaces, or wooden surfaces, then citric acid is what you should aim for.

Knowing all of this can help you make the right choice and actually make it easier to get a detergent that will make cleaning less of a hassle for you.

Frequently Asked Questions

I have now compiled a few questions that are most often asked by users, and I’m sure they’ll help you out as well!

What kind of soap do you use in a pressure washer?

Generally speaking, soaps that are safe for use with pressure washers often come with a label that states so. With that said, the aforementioned soaps are all certified for use with pressure washers and I would highly recommend choosing from them!

How do I make my own pressure washer soap?

Making your own pressure washer soap at home isn’t really that hard. To do so, add a gallon of water, 1/3 of phosphate free laundry detergent in powder form, 2/3 of household cleaner, and you’re practically good to go!

Can I use regular car soap in a pressure washer?

No, not really. Most car soaps and shampoos aren’t really fit for use with pressure washers and won’t give you the result you’re after. It’s best to skip this while you’re ahead and get actual pressure washer detergents for best results.

Do you need soap for pressure washer?

If you feel that soap would make cleaning easier, then you’re right. The right soap in your pressure washer will make it easier for the dirt and stains to break down so that they can be washed away.

Why won’t my pressure washer pull soap?

There are many reasons for something like this to occur. The wrong type of spray tip can often lead to this happening, which is why it’s best to experiment a little and see what works best for your particular brand of pressure washers.

Can I use vinegar in my pressure washer?

Yes, you can! White vinegar is a good choice for using in your pressure washer and will help you remove dirt and other debris easily. Although it’s a good idea to choose a proper detergent with vinegar as a constituent, since that formula is more equipped to make cleaning easier.

Is 2000PSI safe for washing a vehicle?

I would personally recommend going less than 2000PSI if you’re planning on cleaning your car with a pressure washer. At this level, you run the risk of minute damage which I’m sure is not the goal. The whole process might even be counter-productive.

Should you dilute pressure washer detergent?

Yes, absolutely. Pressure washer detergents, in almost all cases, comes in a concentrated mix that needs to be diluted for most effective use. The instructions for each type of mix is different but in general, you’ll need about 20 parts of water to 1 part of soap.

Can I put bleach in my pressure washer?

No! Stay away from bleach as far as pressure washing is concerned. This is because bleach might damage the o-rings in the gun, the hoses and pumps, and the wand.

Should you wear a mask while pressure washing?

While not an absolute necessity, I would still highly recommend taking all the safety precautions you can when you’re setting out to use your pressure washer. It’s safer that way, and you run less risk of doing something that might be damaging.


When it comes to choosing the right type of pressure washer soap and detergent, make sure to choose something that’s applicable for you and the type of cleaning you intend to do. This will help you out in the long run and make your cleaning experience more productive.
