This seems a little controversial to me. Assuming you live in an area where the winters can get very cold and slushy and have done an oil spray or some sort of anti-corrosion treatment in the fall...
- Some say Don't Wash your car weekly during the winter because it takes the oil off, dilutes the salt that's caked on your car and spreads it deeper into the metalwork.
- Some say that it's better to wash the car weekly during the winter to keep the salt off and just plain have a cleaner looking car.
With Canadian winters as harsh as they are my car is never *really* clean so I kind of agree with the first argument. What do y'all think?
