The Best Car Shampoo 2021

The car shampoo that you use to wash your car needs to be pH neutral and effortlessly remove all types of dirt. They are an essential detailing product and choosing the best can help improve your car cleaning results.

Best Car Shampoo

Washing your car yourself allows you to take extra care and use a quality car wash shampoo. It’s also far cheaper than paying a professional valeting company and you get the satisfaction when the paintwork is left gleaming.

The best car shampoo is the AutoGlym Bodywork Shampoo, which is a pH neutral formula that lifts traffic film without harming any waxed surfaces.

Many people make the mistake of using basic washing up liquid to wash their cars. This can have the result of stripping any car wax that you have previously applied to the car because it’s not pH neutral.

Car Shampoo Buying Guide

Car shampoo is an essential product for washing your car and is available in several forms. It’s highly advised that you avoid using household solutions for washing your car as they can be tough on the paintwork.

Depending upon whether you use a pre-wash technique, you may require two different shampoos for use with a pressure washer and then with a car wash bucket.

To help you make an informed buying decision, we have produced the below guide regarding car shampoos.

pH Balanced Formula

The car shampoo that you use will need to maintain a pH balance that’s similar to water. This prevents the shampoo stripping any wax that you have applied previously. Higher alkalinity does assist with breaking up dirt and can be useful in certain situations but shouldn’t be used on a regular basis.

If you drive a convertible with a fabric roof, you may want to avoid regular usage of a shampoo and instead use a dedicated convertible top cleaner.

Amount of Suds

Car shampoos that produce plenty of thick suds will be more effective at removing dirt particles without scratching the paintwork. This is an important feature of any car wash shampoo and you will be able to see the quality whilst comparing between different brands. However, some people may prefer the lack of suds because it provides a sheeting effect that lets water run off the paintwork.

Inclusion of Wax

Some formulas may include carnauba wax and other special ingredients to make them standout from the hundreds of shampoos available. Although it’s not strictly necessary, it’s very beneficial for those that occasionally wash their car. If you intend on polishing or waxing the car straight after washing it, it isn’t really worthwhile paying the extra.

Water Spot and Streak Resistant

After washing your car, there is nothing worse than seeing water spots or steaks upon the paintwork. They are made noticeable under direct sunlight or lighting and can make the car look worse than it did before it was cleaned. Using a quick drying formula will prevent both of these issues and make washing your car slightly easier.

Other Desirable Features

Many brands will state that their car wash shampoo formula is 100% biodegradable. Although this may not benefit your car, it’s environmentally friendly because once the soap is removed from the car, it goes down the drain.

A benefit for person washing the car is the scent from the shampoo. There is an array of fragrances available and it makes using the shampoo slightly more enjoyable and you can often smell it from the car hours after washing it.

Conditioning is often included in the formula of some car wash shampoos. They are designed to enhance the colour of your paintwork as well as making it more slippery, which improves water beading.

Most brands offer their shampoos in a range of different bottles sizes. If you want the best value for money, you will want to purchase the larger capacity bottles. It’s worth noting that some formulas are concentrated, which means you may be getting more shampoo but just in a smaller bottle.

Best Tips For Washing Cars

The simple task of washing your car is something many people get wrong on a regular basis. Using an improper technique can increase the chances of swirl marks, scratches and other defects in the paintwork. Using the correct technique is only half the battle because you will also need to own the correct equipment.

We highly recommend that you adopt the “Two Bucket Method” for washing your car. You will need to purchase an extra bucket but it will ensure that the wash mitt that you are using remains clean and free of any dirt.

You should also chuck away any sponges and invest into a proper wash mitt that captures dirt. If you use a sponge, the dirt becomes trapped between the paintwork and the sponge, which may transfer onto the paintwork and cause scratches.

In terms of your technique, we recommend that you start with the wheels. Begin by using a wheel cleaner and allowing the formula to get to work. You can then spray away the residue and clean any leftover dirt with a wash mitt dedicated for your wheels.

Once the wheels are completed, you can fill up two wash buckets with warm water and the car shampoo. Starting from the top, begin to wipe down each panel and regularly dunk the wash mitt into the bucket using the Two Bucket Method.

Once every panel is cleaned, begin to dry the car using a microfiber drying towel. It’s always recommended to wash your car in the shade or not in direct sunlight. This allows you time to properly dry the car and reduce the chances of water spots.


In order to safely wash your car and not strip any wax from the paintwork, you will need a quality car shampoo. There are hundreds to choose from but the above recommendations are suited to a range of budgets and car washing methods.

It may be tempting to use household cleaning products but you can cause damage to your paintwork. Considering most car wash shampoos are fairly cheap, it’s strongly advised to buy the best you can afford.
