Let's take a deep dive into the foaming mass to reveal just what is happening in there, see if its dollars wasted or well spent!

What is the purpose of Snow Foam? 

To put this into a single sentence definition it is:

"To remove grit and grime particles without human intervention, so that the risk of scratches are minimised during the washing stage"

Snow Foam car wash is a super way to to break down and remove the dirt from your cars paintwork.

Spongy sanding block!

It is a much safer option than attacking your grime coated car with a bucket of water and a sponge. As this can produces swirls and scratches in the paintwork as the ole yellow brick sponge collects the dirt particles and changes into a sanding block!

Think of that sanding block and the pressure you put on it as you scrub away at your cars surface. Can now see why it is best to use a pre-wash product like snow foam to minimise the damage when you do get to the washing stage?.

What is Snow Foam?

Snow foam is a pre-wash product that contains detergent that helps lift off some of the dirt on your car.

It does this by creating a thick clingy foam that sticks to the surface of your car. The thick foam increases the time the detergent stays on the surface so making it more effective.

Dwell time

The time it takes the foam to slide over the bodywork is know as "Dwell time". Because of this increased time spent on the surface compared to normal soap and water the chances of it breaking down and lifting off the grime are greatly increased.

The easing and lifting is provided by surfactants in the foam.

These are:  Substances that reduce surface tension of a liquid in which it dissolved

They are the contact part of the snow foam that is help onto the surface with the foam. The extra time it spends on there eases and lifts the dirt off.

Therefore, no human contact is needed and so the risk of scratching the surface is greatly reduced.

So now we know the purpose of snow foam car wash and what it is, lets take a look at the different types and the foams themselves.

The types of Snow Foam

When choosing a snow foam there are three main types to choose from:

  1. Cleaning Foam
