Best Car Wash Soaps & Shampoos Buying Guide

Types of car wash soap & shampoo

There are several types of car wash soap and shampoo on the market, so you’ll need to ensure you pick the correct one for the job.

Traditional car wash soap simply contains the ingredients needed for you to remove dirt and grime from your vehicle. No additional features are included.

Car wash soap with conditioner includes everything needed to remove dirt, but also has a conditioning feature to help get your paintwork shining.

Car wash soap with wax adds protection to your paintwork while you clean, by adding a layer of wax. It’s all included in the formula, so there’s no need for any additional work. It is only a temporary layer, however, so it’s ideal for topping up an existing full layer of wax.

If you’re looking for a product that can top up your wax layer, choose Meguiar’s G17701 or Mothers 05674.

Factors to consider

Concentration

The level of concentration of your chosen car wash soap will impact how many washes you can get out of one container.

You can check the manufacturer’s advice on dilution to get a better understanding of this. The more water a manufacturer recommends per ounce of soap, the longer it will last.

Foaming properties

The more suds a soap produces, the more effective it is at collecting dirt from your paintwork. You’ll need to create a thick lather to reduce the amount of scrubbing that needs to be done, which in turn reduces the risk of damage to your car.

Environmental friendliness

As you’ll be rinsing the soap off your car, it will eventually end up in a storm drain. It’s important that you pick a soap that’s biodegradable. Otherwise, it can be very damaging to the environment.

pH Level

If you pick a soap that’s too acidic or alkaline, you can strip any existing layers of wax your car may have, or even start damaging your paintwork.

Pick a soap that’s pH balanced with a hint of alkalinity, as this will help to break down dirt and grime.

Blemish resistance

Many products used on your car’s paintwork can leave behind unsightly water spots and streaks. These days, some manufacturers are formulating their solutions to dry quickly to reduce the risk of this damage occurring.

Scent

It may not impact how your car looks after a wash, but scents can differ greatly among car wash soaps and shampoos. Look out for any mention in the description to ensure it’s to your personal taste.

Equipment needed

Before washing your car it’s important to have the right tools for the job available to you. These include:

  • A hose connected to a water supply
  • Your choice of car wash soap/shampoo from this list
  • 2x microfiber or sheepskin wash mitts – one for the body, and one for the wheels
  • 2x buckets
  • 1x large microfiber waffle-weave drying towel
  • 2x small microfiber waffle-weave drying towels

How to wash a car

You need to ensure you’re working effectively and safely to remove as much dirt as possible and minimise the risk of damage to your paintwork.

Our guide on how to wash a car properly gives you all the information you need to do this, but in summary:

Prepare two buckets, one with the diluted car wash soap and one filled with water for rinsing.

Rinse the car with a hose or pressure washer first to remove any surface dirt, and then clean the wheels.

Once the wheels are done, move onto the paintwork and windows, using your soapy water.

Rinse the car again to get rid of the dirt and excess soap, and then dry thoroughly with microfiber towels to ensure no streaks or water marks are left.

How often should I wash my car?

It will depend on how often you use your car, the weather in your country, and how much you value your car’s appearance. A general rule of thumb is once every two weeks.

Many people neglect their vehicle’s paintwork by leaving it months between washes, which increases the risk of faded paintwork, damage, and rust.

Should I use a foam gun?

Foam guns or cannons are a great way of applying car wash soap suds quickly and effectively, but they aren’t a must.

They can get quite pricey, and you can get similar results from using the two-bucket system described in our article on how to clean your car properly.

If you love your car and do want to buy a foam gun, they provide a great way to apply your suds, and you’ll have a lot more fun in the process!
