The Best Snow Foam

Snow foams have surged to prominence over the last few years and are now an integral part of the car wash process. We take a look at the best snow foam to buy and explain their uses and benefits, analyse their differences and any other considerations.

First of all, let’s just clarify exactly what a snow foam is. In simple terms, it’s a pre wash product that is used to soften up and remove as much dirt and grime as possible before washing the car. There is often confusion over whether a snow foam can be used as a shampoo and as a hand washing product, the answer is no, it definitely can’t. To clarify – a snow foam should always be used as a pre wash and not a shampoo substitute.

Simply load up the foam lance bottle with product and begin applying to the car working from the bottom upwards. Ensure full coverage of the entire vehicle and allow 10 minutes for the foam to dwell on the surface. Note – if you’re doing this in direct sunlight you’ll have to reduce the dwell time to ensure the foam doesn’t dry on the paintwork. After 10 minutes, rinse off the snow foam ensuring that it’s completely removed. You’ll have removed the majority of dirt and grime and are now ready to safely start the contact wash stage with shampoo of your choice.

What Are The Benefits Of Using Snow Foam?

Using a snow foam as part of your car cleaning process is extremely beneficial and is something that we strongly reccommend. Snow foam is a pre-wash product which is to be used before any wash mitt’s or sponges come into contact with the paintwork. The aim of snow foam in it’s simplest form is to remove as much dirt and grime from the paintwork as possible prior to the washing stage.

Let’s simplify the benefits of using snow foam;

Reduce scratches and swirl marks – A snow foam will reduce scratches and swirls being imparted onto your vehicle removing dirt and grime from the paintwork before any contact is made. The aim with a snow foam is to remove as much grime as possible prior to a wash mitt or sponge being dragged across the paintwork. Imagine a heavily soiled car that hasn’t been washed for a while, and then imagine a wash mitt or sponge dragging all that grime across the paintwork whilst washing the vehicle. Naturally, the car is going to end up with scratches and swirl marks. A snow foam will dwell on the surface of the paintwork, break down the grime and road salts etc and significantly reduce the amount of debris and grime left on the paintwork prior to washing.

Easier wash process – A good quality snow foam will make the entire wash process much easier. By breaking down and removing the majority of the dirt and grime, it’ll make it much easier to wash the car and remove the remaining grime. This will result in the job being completed much quicker and efficiently.

Cleans hard to reach areas – A snow foam will provide light cleaning of all areas of the vehicle, including those hard to reach areas such as inner wheel arches, underneath the vehicle, door seals etc. Some of those areas are often overlooked when the car is washed via a wash mitt or sponge and can therefore become extremely dirty and build up heavily very quickly. The snow foam will provide mild cleaning of the areas which would previously be untouched.

Snow Foam vs TFR

What’s TFR I hear you ask. TFR is Traffic Film Remover and is often touted as an alternative to snow foam. Both products are designed to be used as a pre-wash product but there are some key differences that you need to be aware of.

Traffic Film Remover’s are commonly used at hand car wash establishments (god forbid!) and feature frequently there due to their rapid cleaning ability. If you’ve ever visited a hand car wash and they start spraying the lower half of your car with a pump sprayer to begin with, it’s almost certain to be a TFR that they are applying. They apply this because it breaks down the dirt rapidly and is also extremely cheap when bought in bulk. TFR however has two extreme negative points, which are;

Damage to paintwork and trim – TFR’s are extremely powerful and can very easily cause damage to paintwork and trim. Chrome trims are particularly susceptible to damage from TFR. If they TFR is not removed pretty quickly after being applied, it’s highly likely to cause damage to the car.

Strips waxes and sealants – A TFR will completely strip and remove any previously applied waxes or sealants. If you’ve spent a good few hours waxing your car and then apply TFR to it as part of your wash process the following week, you’ll be erasing all your hard work from the previous work and leaving your car unprotected from UV damage and road grime.

By contrast, a good quality snow foam will not cause either of the above problems. Ensure that your snow foam of choice is LSP (Last stage protection) safe and you’ll be just fine, you’ll not have to worry about causing damage to trims etc.

How Do I Use Snow Foam?

Snow foam can be used a range of different ways and with the use of a range of equipment. First of, we think snow foam works best when used in conjunction with a pressure washer and dedicated snow foam lance. Whilst it’s not imperative that you do that, we think it provides the best performance and maximises the cleaning ability of the foam. In this scenario, follow these easy steps to use your snow foam

  • Dilute the snow foam with water. You should always follow the manufacturer’s guidelines on what ratio to dilute but generally speaking, an inch of foam mixed with water should give a nice thick foam. You can ofcourse adjust this and add more foam which will create an even thicker foam.
  • Begin applying to the car via the pressure washer working from the bottom upwards. Ensure the car is completely covered and go over heavily soiled areas a few times to ensure maximum cleaning power.
  • Allow to dwell for 5-10 minutes depending on weather conditions and the specific snow foam that you’re using (Autobrite Magi Foam can dwell for up to 30 minutes!)
  • Thoroughly rinse the car ensuring that all snow foam is removed, paying particular attention to the lower half of the vehicle.
  • You’re now ready to wash your car with the shampoo and wash mitt of your choice

Snow Foam FAQ’s

Q. Can I use snow foam on a convertible roof?

A. Yes, you can use snow foam on a convertible roof. The same principle as cleaning the main body of the car applies, use snow foam as a pre-wash and then follow up with a shampoo and wash mitt to give it a thorough clean. We reccommend to follow up this cleaning and treating with a dedicated convertible roof treatment product.

Q. Do I need a snow foam lance and a pressure washer?

A. No, you don’t need a snow foam lance and pressure washer but we would always suggest using them as we think you’ll get much better results. If you don’t have access to a pressure washer you could always use a spray foamer. A spray foamer won’t create a foam that’s as thick as when using a pressure washer but it’ll still work well.

Q. Why isn’t my snow foam very thick?

A. Your snow foam may not be as thick as expected for a number of different reasons. First of all, you may not be using enough snow foam. Always follow the manufacturer’s reccomended guidelines but generally speaking, an inch of foam diluted with water should always produce a relatively thick foam.

Secondly, if you’re using a foam lance, you may not have it adjusted correctly. Most foam lances contain an adjustment dial on the top of the bottle, turning one way will increase the foam mixture, turning it the opposite will decrease it. Try adjusting the dial and see how it impacts the foam that it produces.

Thirdly, there will always be a variance between snow foams in terms of the thickness of the foam that they produce. Autobrite Magi Foam produces an incredibly thick foam (almost like shaving foam in some circumstances), whereas Bilt Hamber Auto Foam doesn’t produce a particularly thick foam.


In summary, we think snow foam’s can have an extremely positive impact on your car washing experience and help keep your car looking it’s best. A good quality snow foam will ensure your vehicle isn’t unnecessarily scratched or covered in swirls whilst removing road grime and dirt and for that reason alone it’s well worth the relatively small outlay. Aside from that, it looks extremely cool and will be sure to impress your neighbours!
