how to wash your car like a pro with a foam cannon in the winter! This is part of my auto detailing like a pro series on how to clean your car inside and out! There are several ways to winter wash your car but for me, this is the best way to get the best clean possible whether its cold or warm outside with these care washing tips. The first method is using a foam cannon and pressure washer to remove the heavy dirt on the surface. I show you how to use a foam cannon car wash properly. I then like to follow up with the two 2 bucket method using grid guards and separate microfiber mitts for the paint and the rims/tires.
