Buyer’s guide

In many cases people aren’t really bothered by what they use to wash their cars will. Clearly we see just how getting the wrong shampoo for your car lead to the detriment of your car’s physical appearance. There are a few factors that one should consider when getting car shampoo to ensure protection of the car.

Clean cars will elevate your mood a whole lot more so let’s have a look at what you need to be on the look-out for.

Suds formation

Finding out the foaming properties of the shampoo is very important. The more foam there is, the more efficient the cleaning will be. This is because the suds are able to have the dirt particles easily suspended without needing to scrub.

Make sure that while the shampoo might have foaming properties, they are long lasting and you don’t risk the soap going flat in your wash bucket. If you’re going to be using a foam cannon, then having a high concentration will be better for maximum effectiveness.


Depending on how concentrated your shampoo is, you’ll be able to tell whether the product is durable or not. The higher the soap concentration is, the more durable the soap will be.

This is because you will only need to use a small amount of the product and achieve maximum results. If the concentration is lower, then you’ll need to use more soap to try and achieve the results you want.

For a good balance or ratio, 1 ounce of soap should be diluted in 1 ounce of water to attain positive results. Many bottles now come in 16, 32,48 and 64 ounces which interestingly are all divisible by eight.

pH level

The pH level is what is used in determining acidy or alkalinity of the solution. When you have extremes of this pH level, then you risk corroding the paint, wax as well as the coat. The optimal pH level is when it is alkaline to have complete breaking up of dirt/grime which are acidic.

Eco friendliness

The environment has to come first in all our transactions and that doesn’t change when it comes to car care products. One factor you want to look for when buying your car shampoo is whether the ingredients are biodegradable.

Once you rinse off your car, the products go to the earth. While your car might not necessarily feel the effects, you will be contributing to a more severe problem that will have repercussions on you and future generations.


While scent might not be an issue for most, some shampoos can have really pungent smells and could even cause allergies. Try go for scentless shampoos that don’t have the potential to offend your nostrils or someone else’s’.

Value for money

As is with most products, you want to see the value of what it is you’re buying. Don’t spend so much money on something that will barely even form suds and worse still leave your car with more damages. Instead of buying small bottles consistently and spending more, go for the 64-oz bottles that could last you up to a year.

Water spots/streak resistance

Again look for shampoos with fast drying solutions so that your car isn’t left looking disastrous after a wash. The water streaks and spots left on the car after wash actually have a damaging effect on the paint and not unless you’re out for revenge and decide to take it out on your car, we suggest you leave out such products.

Foam Cannon Vs Foam Gun

When it comes to cleaning cars you’ll often hear people mentioning foam guns, lasers and as we’ve been discussing, foam cannons. But for some reason, foam guns and foam cannons are the most confusing. Is there a difference?

Yes, there is. While both of these typically save you the hustle of hand washing your car, one is more reliable. Let’s see how:

A foam gun is attached to your hose and is much simpler to use compared to a foam cannon. This means that:

  1. It isn’t as effective as this is dependent on the water pressure on your hose and in all honesty there’s hardly any pressure in a garden hose.
  2. It produces weaker foam that will run off your car so fast that no work will have been achieved i.e. you’ll still have a dirty car.
  3. It is a waste of water. Since the pressure coming from the garden hose isn’t much, more water will be needed for the job instead of if you were using high-pressure water.

A foam cannon on the other hand, is a bit more complex than the foam gun but once you get the hang of it, you’ll never go back to using the foam gun. For a foam cannon to work, you need a pressure washer as well as high quality connectors made of brass for proper attachment to the pressure washer. This effort is important because:

  1. It saves you water. Due to the high pressure being applied to the foam gun, it saves you a ton of water and is still highly efficient. If you live in areas with restrictions on how you should use your water, then don’t worry; you’ll still stun in your clean car.
  2. The high water pressure combined with the foam makes for one magical burst. Using a foam gun will honestly leave your car looking like you spent serious dollars to get it looking so clean.
  3. It is time efficient. For some they enjoy hand washing their own car on those lazy Sundays while they enjoy a good old bask in the sun. That’s not the case with everyone though so if you’re the type who just doesn’t have the time then the foam gun will get you that professional clean look in under no time. It’ll leave you enough time to run errands.

So there you have it; while it might be easier to use a foam gun, it will waste your time as well as water. We advise you go with a foam cannon and enjoy all the benefits that come with it.

Foam Cannon Tips & Tricks

1 – The right pressure washer

Aside from choosing the right foam cannon, choosing the right pressure washer is equally as important. They offer two options i.e. gas pressure washer and an electric pressure washer. Gas pressure washers are great at delivering thicker foam because they offer more PSI (Pounds per Square Inch) and GPM. Electric washers on the other hand are must a lot quieter and not a drag to move them around. You need to look for pressure washers that have the right GPM & PSI specifications of the foam cannon you’re using.

2 – The right soap

Choosing the right soap goes without saying that it’s very important. You don’t want to get yourself soap that will give you some barely-there suds. Auto soaps are especially formulated to create the right kind and amount of suds needed for your car. Chemical Guys Snow Foams were actually the first in designing car soaps specifically for foam cannons. Most, if not all their car washing soaps will work well for your foam cannon.

3 – Secret ingredient: warm water

Use warm water for aeration of the water and soap mixture to fully enjoy thick suds. Don’t shake the mixture violently but rather swirl the bottle gently in a circular motion; you want to avoid foam forming in your bottle.

4 – Rinsing

A quick top to bottom rinse is advised before you start foaming your car to remove the huge dirt chunks before they have a chance to rub into that meticulously done paintwork.

5 – Maintenance

Using your foam cannon doesn’t end with you having a clean car and as such avoid storing it with the remnants of soap and water still in there. Leaving these components in your bottle creates calcium deposits which lower the performance of your foam cannon the next time you’ll want to use it.

Empty it and rinse thoroughly with plain water. To ensure it is clear of any soapiness, after you have rinsed the bottle, refill it with plain water and reattach it to the foam cannon and spray it out. Do this until you are sure that there’s no more soapiness and keep your foam cannon at a safe place for use next time.


Why should you buy a good shampoo?

The reason behind sourcing out a good shampoo is because you want to get the dirt off of your car with no damage whatsoever going on the paint or wax. Good shampoos have been formulated with care to ensure that they are not aggressive while lifting the dirt off of your car. They provide slickness as well as lubricity ensuring no accidents happens.

Can I use my really great kitchen soap to clean the car?

Absolutely not. The chemicals and surfactants found in household cleaning products are aggressive and way too hostile for the delicate paint and wax on your car. They are manufactured with an aim of removing anything stuck on say your plate or cup. There’s no gentleness in mind here.

What makes a great shampoo for cars?

A good shampoo is dependent on the purpose you want it to serve. The factors you’ll need to consider are as we had mentioned; is it biodegradable, it the foam thick enough, is it concentrated, etc.

Check out the buyer’s guide section for a detailed explanation.

Is it okay if I let the foam dry on my car?

No. By letting the foam sit on the car too long, it will lead to damage of the paint and wax. Whether or not you’re using a foam cannon, the point is to have the car clean and not to have to spend more taking it to the auto emergency room.


Generally, a good foam cannon is only as good as the soap you use in it and vice versa. And for this article, our best car shampoo for foam cannons has to be the Meguiar’s Gold Class Car Wash. This is simply because it has proven itself a worthy contender despite its low price; it’s not as cheap as people make it out to be.
