How to apply snow foam
This guide will enable even the newest detailing enthusiast to achieve professional grade snow foam results.
1. Mix the snow foam solution
Begin by diluting your chosen snow foam shampoo with water within the reservoir of your foam cannon or gun. Most products have a recommended ratio of 1 part snow foam to 5 parts water but it can vary. Making your mixture more concentrated will create thicker suds but this can also result in wasted product, especially if you're performing regular washes.
2. Cover your vehicle in thick suds
Attach your cannon or gun to your pressure washer or hose and cover your vehicle in a layer of snow foam. Start from the top and work down to ensure complete coverage. The snow should be tick enough to cling to the surface, is at this point that it will begin to break down and lift dirt without you directly contacting the surface.
3. Let the snow foam dwell on the surface
Let the snow foam sit of the surface for around 5 to 10 minutes. The longer you leave it the more effective it will be but after 10 minutes you risk the product beginning the dry. This could result in water spotting and swirl marks.
Avoid applying snow foam in direct sunlight (this recommended for any car wash session) as this will significantly speed up the drying process and make it much harder to rinse off.
4. Thoroughly rinse the snow foam off
Rinse your car making sure you remove all snow foam and loose dirt. This should leave a clean surface ready for further detailing.
5. Perform a contact wash with a 2 bucket method (optional)
If you're wanting to perform a thorough car wash or have stubborn dirt left, follow up your snow foam with a contact wash. The surface should be free of most dirt and grime which makes a contact wash much safer.
To further reduce the risk of scratches we recommend a 2 bucket wash method. This involves using 1 bucket for your wash suds and another bucket for rinsing.
6. Final rinse and drying
Give your car a final rinse to remove remaining soap residue before drying the surface with a quality microfibre or drying towel. This will prevent water spotting and leaves the paintwork clean and dry for additional waxes.
