Snow foam shampoos are designed for softening the dirt and grime on your vehicle’s exterior car surface. So how does this happen? When you apply the snow foam solution onto your vehicle, its advanced suds stick to the dirt, grime and muck. When allowed to sit for a few minutes, it naturally starts dripping off the surface of your vehicle and in the process, takes down a substantial amount of dirt along with it. Its foam can handle the big particles that a regular car washing shampoo cannot, as it is more penetrative and ensures that dirt loosens fast and easily to leave the vehicle’s surface less prone to damage during the cleaning process.
