Snow Foam
Which Snow Foam Do I Need?
Every snow foam does the same basic job: it clings to the paint, gives the cleaning agents time to work, and carries loosened grit away when you rinse. Where they differ is strength and what they are safe on, so the right one depends on how dirty the car is and what protection is on it.
Engage, pH neutral. The one for regular maintenance washes. Thick, long-dwelling foam that is fully safe on wax, sealants and ceramic coatings, so you can use it every wash without wearing your protection down.
Assault, high cleaning power. An alkaline snow foam for winter grime, motorway dirt and cars that have gone a while between washes. Still safe on wax and sealants.
Snow Lux, coloured snow foam. Alkaline foams in green, yellow, blue and red with a scent to match. Extra cleaning power for moderate to heavy dirt, and the most enjoyable way to start a wash.
How to use it. Snow foam goes on through a snow foam lance on your pressure washer. For Engage or Assault, add 50ml to the lance bottle and top up with 450ml of water. Foam the whole car, let it dwell, then rinse thoroughly before it dries, and avoid direct sunlight. Mixing a different strength? The dilution ratio calculator will work it out for you.
Snow Foam FAQs
Everything you need to know about snow foam.
What does snow foam do?
Snow foam softens and loosens dirt, road grime and traffic film before you start your contact wash. Because it clings to the paint, it has time to work, and when you rinse it off it takes a lot of the grit with it. Less grit under the mitt means less risk of swirl marks.
Is snow foam safe on wax, sealants and ceramic coatings?
Engage is pH neutral and safe on wax, sealants and ceramic coatings, so it is the one to use on a protected car every wash. Assault is stronger but still safe on wax and sealants. Snow Lux foams are alkaline for extra cleaning power, so if you have just applied protection and want the gentlest option, choose Engage.
Do I need a snow foam lance?
For thick foam, yes. Snow foam is designed to go through a snow foam lance on a pressure washer. Snow Lux can also be applied with a foam pump sprayer if you do not have a pressure washer.
How much snow foam should I use?
For Engage and Assault, use 50ml in the lance bottle topped up with 450ml of water. Snow Lux uses 50ml for a lighter foam or 100ml for a thicker one. Every bottle has its own dilution on the label, and the dilution ratio calculator helps if you are mixing a different amount.
Does snow foam remove all the dirt?
No, and it is not meant to. Snow foam is a pre-wash stage that takes off as much loose dirt as possible before you touch the paint. Follow it with a contact wash using a car shampoo and a clean wash mitt.
What is the difference between snow foam and pre-wash?
Snow foam is one type of pre-wash. The wider pre-wash range also includes Nitty Gritty, a dilutable degreaser you spray onto the dirtiest areas like lower panels and wheel arches before foaming the whole car.
A safer wash starts before the shampoo stage.
Once the foam is rinsed off, move on to a contact wash with a car shampoo and a clean wash mitt, then dry with a soft drying towel.
