Car Wash Soap Buying Guide

To keep your car looking great, you’ll need to wash it on a regular basis. The best way to really get all the grime and dirt off whilst maintaining your perfect paintwork is to do it yourself. However, if you’re going to wash your car on your own, you need to ensure that you have the best car wash soap that’s effective and safe for your car.

There are many different soaps on the market to choose from, which can be overwhelming, particularly if you’re washing your car for the first time. To help you make an informed buying decision, we have produced the below guide regarding car wash soaps.

Effective Cleaning

The main purpose of a good car wash soaps is to be able to effectively clean your vehicle. If your soap doesn’t get the dirt and grime off your car’s paintwork in just a few swipes, it’s going to be very frustrating to use.

However, when it comes to the wheels, we strongly recommend using a wheel cleaner to remove the tough dirt and brake dust. The main reason for this is because it will be far more effective and prevent tough dirt remaining on the car wash mitt and potentially transferring onto the paintwork when you return to washing.

Most car washes have ingredients in their formula that keeps your car looking clean and shiny for many days after washing it. We advise that you look at the breakdown of the soap formula to see what sort of conditioner is included in the product.

A good soap should leave your car shiny and brighten up the color even without wax included. Ideally, it should also leave a protective layer that prevents your car from getting dirty quickly again. 

Safe for Waxes

If you like to wax your car, you will need a soap that doesn’t contain any abrasive qualities that may take the wax off of your car as you are cleaning it. A quality car soap will work with a wax instead of taking off removing it.

A reliable indicator that a soap is safe to use with a wax is if it’s labeled as being pH neutral. Many car wash soaps actually contain wax in them as well, so you can get your car clean and shiny all in one go.

These types of soaps are the perfect option for car enthusiasts who don’t have much time to spend on maintenance. A wax not only makes the finish of your car look beautiful, but it also protects your paintwork and keeps you car clean for a longer period of time.

Since you will be washing your car outside, it’s important to look for a soap that’s biodegradable. This means that the ingredients in the soap naturally break down and absorb into the earth, instead of harming any plants or animals that are outside.

A biodegradable soap also won’t create any outdoor waste. If you are particularly concerned about the safety of your soap, look for a product that’s made using natural ingredients.

Works With Multiple Washing Methods

Everyone has their own preferred method for washing their car. Some people like to hand wash it using a bucket and soap, while others prefer to use a foam gun or a pressure washer for a more powerful, efficient wash.

You also may want to spot clean your car every so often to remove small areas of dirt and debris. Before purchasing any car soap, make sure it’s a formula that can work with your chosen car wash method for maximum efficiency.

Bottle Size

The size of the soap bottle is something else to consider when making your final buying decision. The larger the bottle, the more value you will get for the price.

You should also note the strength and concentration of the soap and consider how much you are going to need for one wash. A very concentrated wash also allows you to get the best value possible.


Most car wash solutions have a smell to make the car wash experience more pleasant. Smell is a very personal preference, so it’s helpful to note the smell of the car wash before making your purchase.

Some soaps even come in a few different fragrances to choose from. The smell of the car wash not only makes washing your car more fun, but some soaps also leave a lingering smell that you might notice when you’re around your car. Most car soaps feature a fruity or a clean, laundry-like scent.


Another factor to consider when shopping for car wash soaps is its lubricity as it indicates how slippery the car soap is. A slippery soap is much easier to use, because it spreads out easily and covers the surface of your car, which makes for more effective cleaning.

A slippery soap also helps the dirt and debris slide right off of the car, so you won’t have to spend any extra time scrubbing away at the car.

Avoid Streaks

You will always want your car to have a beautiful, streak-free finish with no extra marks. Ideally, the soap should be usable on all different types of surfaces so you can clean your entire car without leaving marks. The soap should also work well in all different types of weather. Some car wash soaps are much more likely to streak on a hot, sunny day than others.

Since washing your car on a warm day is going to be more pleasurable than doing it on a cold or rainy day, it’s important that your car wash is appropriate for use in all temperatures.

All of the recommendations in this article aim to provide streak-free results when using a high quality car drying towel to dry the car.


Washing your car at home gives you greater control over the way the finish of your car looks. Investing in a good car wash soap allows you to clean your car whenever you want and also very economically as you won’t have to pay the drive through premium.

It may be tempting to make your own car wash soap but we highly recommend avoiding the hassle of it all and buy one of the recommendations. Risking damage to the paintwork with a home recipe is simply not worth it. All of our recommendations above are suitable for every budget and include a wide range of formulas.
