What is snow foam?

Snow foam is a pre-wash product designed to loosen and lift surface dirt, grime, and road film from your vehicle before contact washing. Applied through a snow foam lance or snow foam gun, it clings to your paintwork in a thick blanket of foam, breaking down contaminants that could otherwise scratch your car during a wash.

Adding car snow foam to your cleaning routine helps reduce swirl marks, protect your paintwork, and achieve a deeper clean with minimal effort. It’s a must-have for detailing enthusiasts and time-poor drivers alike.

How to use snow foam for the best results

1. Rinse your car with water to remove loose dirt.
2. Fill your snow foam lance or gun with the correct dilution of snow foam (check your product label).
3. Attach the lance to your pressure washer or use a compatible snow foam gun.
4. Cover your car in a thick layer of foam, working from bottom to top for better cling.
5. Leave the foam to dwell for 5–10 minutes (don’t let it dry).
6. Rinse thoroughly with clean water.
7. Continue your wash routine with shampoo, car polish, and car wax for a full finish.

Choosing the right snow foam gun or lance

To get started with car snow foam, you’ll need a snow foam lance or snow foam gun that’s compatible with your pressure washer. A snow foam lance typically connects to pressure washers and delivers thick, clinging foam, while foam guns attach to garden hoses and are ideal for lighter use.

Make sure to:

• Check compatibility with your pressure washer brand (e.g. Karcher).
• Look at connector types and PSI rating.
• Consider portability: if you’re using a cordless pressure washer, you may need a more compact lance or adapter.
