Hi All, I live in the Northeast with all the winter salt to keep the roads ice free. My question is: Is it neccessary to get an under-carriage wash at the car wash? If yes, how often and what could happen if i do not get it? Thanks in advance...
There are two issues involved with Winter Salt & Under Body Flushes....
#1 Where do you park your Salted Car... Heated or unheated(cold) Parking?? Heated Parking and under body Salt is a Bad situation... It's time to flush the Salt off via a Car Wash...
#2 Is the under Body surface E-Coated (Electrostatic Baked Paint) or Hot Melt Wax Dipped.......??
Running thru the Car Wash with the UnderBody Flush might eventually remove too much Hot Melt Wax protector.....
Again... heated parking with clinging salt & water is never a good situation....
Around my area they all use recycled water. It is best to check. Also, most well water (I live in the country) in our district has some salt in it.
Salt doesn't really dry. A layer or dried (so it appears) salt on metal attracts moisture 24-7 and the layer of moisture, being so very thin, is saturated with oxygen from the surrounding air. Steel rusts very quickly under these circumstances. Things can accelerate if the vehicle is parked on a lawn or in a grassy field as grass takes in CO2 and releases Oxygen all around and under the vehicle. Salt and grass makes rust so quickly you won't believe it even after witnessing it for yourself.
