Elegantly trapping dirt and grime in its luxurious foam, the shampoo smoothly removes filth from every part of your car. And it does so without leaving any kind of swirl marks or causing any sort of wax strips.

Buying Guide

Reading the list above will surely give you an idea of how much variety exists even in a simple product like a car detergent. Surely then, it wouldn’t be wise to assume that getting a pressure washer car cleaner is an easy feat. Particularly for those who are buying it for the first time.

This guide is made to cater to such needs. It will summarize the things that you need to know before buying a pressure washer car cleaner.

The main thing that you should be aware of is the cleaner’s type and ease of its application. Of course, there are well-known brands all around that might be your first choice for a cleaner.

But it has been found that not all branded products offer the effectiveness you need. This is especially true when the specifications of the product do not match your requirements.

Cleaners are not one-size-fits-all types of items. Every cleaner differs in one way or another. And it is the job of the buyer to be as clear as possible about what they want. And this mainly depends on what type of car you own.

With this, let’s proceed with the factors that are important when buying a quality cleaner.

Car’s Coating

The very first thing that you need to figure out is the type of surface of your car. More specifically, you need to know what type of paint has been used and any type of protective coatings.

The major concern is the coating, though. The protective coating is applied over and above the car’s paint to avoid deterioration. But these coatings may be sensitive to certain chemicals or polymers found in car cleaners.

There are quite several coatings. More commonly, cars have wax coatings. You might have heard of the phrase just had my car waxed.

This simply means the car has been through some detailing with wax applied to the body.

Then there are sealants. These are manufactured by hand, with chemical engineering playing a major role in their production. Sealants are undoubtedly more powerful than wax coatings. While wax may not last for more than 2 months, sealants can sustain the shine and glow of your car for up to 6 months.

Finally, there is ceramic. This is by far the most superior form of coating. But with such high quality comes a heavy price tag. However, it is the most durable of all.

Given these types of coatings, you will need to select the cleaner you want carefully. The cleaner should not contain chemicals that might damage the coating material. For instance, some cleaners may cause what is commonly known as wax stripping.

This simply means that cars with wax protections may experience some wax being stripped off due to low-grade cleaners.

Remember, these coatings are there not just for making your car look beautiful but also for protecting the paint within.

Water Beading/Sheeting

Somewhat related to the point above regarding protective coatings concerns the phenomenon called water beading or water sheeting. Both are different things.

Some coatings cause water beading when you apply cleaners to the car’s surface. Basically, when you clean, beads of water may form on the surface. You might have seen them in pictures. They give an effect of multiple spots standing out.

These beads form because certain coatings ceramic, particularly are made to ensure that water repels off the surface. This repulsion also helps in lifting off dirt and grime with the water beads.

But here’s the catch, water beads may be good for removing dirt, but they can be harmful if they tend to stay on the surface for long and do not slide off easily. This is because the water in those beads may evaporate.

But such evaporation can leave behind certain minerals that eat off the coating and even the paint.

Some cleaners ensure that water beading is enhanced. That is, such cleaners have certain polymers that ensure the beads are easily rinsed off.

So, if your car has ceramic coatings, you will be better off getting a cleaner that specifies its ability to remove such beads.

On the other hand, water sheeting is the phenomenon when water actually doesn’t form beads but slides off in streaks from the surface, taking the dirt and grime with it. This is usually considered better than water beading, as the water has fewer chances of remaining on the surface.

You can get cleaners that enhance both water sheeting and beading. So make sure you read the label or ask the retailer to confirm if the cleaners will help in this regard.


You might have read in the list above that many cleaners claim to give you luxurious foaming suds when used.

These thick suds are actually very important when it comes to cleaning a car. The thicker the suds, the more easily dirt and grime particles cling onto the soap, and the easier it becomes to rinse them off.

Also, since the foam acts as a barrier between the dirt and the car’s surface, the dirt particles do not cause any scratch marks as they slide off the surface.

When moving from one part of the car’s surface to another, Dirt or grime can cause ugly spots. Thick foam avoids this since it basically serves as a lubricant and doesn’t let friction get in between the waste particles and the car.

Also, foaming helps in easy rinsing. Cleaners should allow you to do this. Otherwise, you might end up wiping off the cleaner from the surface by hand. If too much force is applied in removing the cleaner, it can cause swirl marks on the surface. This again aggravates the look of the car.

So, make sure that you get a cleaner that can give you thick foams.

Tools to apply and dry

There are many tools that you can use to clean your car. Car cleaners shouldn’t be applied directly. They need to be diluted in water and then applied using different tools.

The application instructions will be given on the product’s labeling. If not, inquire about it from the seller.

More commonly, you can use a foam gun or foam cannon. These tools help in producing a lot of foam when applied to the car. They are kind of like sprayers that spray the cleaner onto the surface. You can then rinse off with a pressure washer.

If you want something traditional, you can get a cleaner that works with car mitts. Basically, you will need to apply the cleaner diluted in the water – section by section by rubbing the cleaner onto the car. Next, you may need to wipe it off.

In all cases, you will need to dry off the water. You can usually towel-dry, which means getting a piece of the clean, dry towel and rubbing it all across the car’s surface. But some cleaners allow you to air-dry as well.

You will again need to check what type of drying you can do with the cleaner you are buying. Remember, cleaners that specify to towel-dry should not be air-dried. It may not remove the cleaner properly from the surface, and this can cause paint damage.


And with this, you know enough that you can go out and get a high-quality car detergent that can be used with a pressure washer.

Of course, there are quite a few other things, such as the scent of the cleaner. Cleaners come in many scents. You can get the one that you like the most.

Also, do ensure that the cleaner is bio-degradable. Once you rinse off the cleaner, it will be drained out to water sewages or perhaps into other water streams. A bio-degradable cleaner will not harm life in these environments. So just an extra precaution to protect the environment.

What does pH-neutral mean?

pH is a measure of how acidic or basic a particular solution is. Water, for instance, is pH-neutral with a pH of 7. A pH of less than 7 means the solution is acidic, while a pH above 7 means basic.

Both basic and acidic solutions have their own uses. But when it comes to car detergents, pH-neutral is the best choice as they don’t cause any damage to the car’s paint.

Can all car cleaners be used under sunlight?

No. There are only a few cleaners that may allow you to wash your car under sunlight. Otherwise, the common practice is first to let your car cool down and then washed under shade.

This is because sunlight may cause water spots on the car’s surface, and this again may cause damage to the paint.

How does high concentration help?

A highly concentrated cleaner means that you only need to use a small amount of soap in water. This will be enough to give you sufficient foam or suds to clean off the car effectively.
