Like the title say do they cause rust ? Just seen a local detailer on the news. They were talking about dirty vehicles and the salt and chemicals effects on your vehicle. The detailer stayed that it rust your car and undercarriage. Also do any of yall clean the undercarriages of vehicles and how? He also stayed that the salt and chemicals can scratch your car, as he was whiping a dry panel with a terry cloth.

I would have to say yes I've seen it a lot around here it seems the newer cars it happens in the paint chips. I wash my undercarriage I turn the sprayer on and put it under the car a lot of crap comes off
 
You could say they do...In a round about way.

Corrosion/Rust is the result of an electrochemical reaction combining iron and oxygen to form iron oxide.
To really get the iron-oxide party off to a good start: Bring in some "impurities" and an electrolyte.

That's where chemically-laden melted ice/snow (née: water) can come into play...can step-up the rusting process.

Now it's just lying-in-wait for something to come along and kick up some of this ion-filled road spray, into moisture-trapping crevices, in and around a vehicle.

Best to rid a vehicle of this contaminate ASAP!!

It's more like it will speed up the rusting process if it's not removed...

Metal will rust, even stainless steel, the speed that happens depends on what the metal is subjected to.
 
They started using Liquid Calcium in New York State on the roads.
The guys putting it down say you should be able to hear your car rust as you drive...................
 
That's not good news about the calcium. I thought the good old fashion salt was bad enough!

If you have a car that has lived in the salt-less climate and put it next to a northern tier car and look underneath there will be a noticable difference, even on one that is well cared for.

To combat the effects, I spray out the wheel wells and undercarriage. This is either done by hose, coin-op car wash wand, or a touchless car wash that has an underbody spray.
 
Salt and such will rot a car quick. One method to use,if practical, is hook up a lawn sprinkler under the car and drive slowly ove it. Helps a little or alot depending on water pressure
 
Yes and yes. I just try to rinse off as much as I can as often as I can, when the temp gets above freezing.
 
Its obvious, look at the vehicles that do the spreading. I try to run mine through a touchless 2-3 times after the salt goes away.

:laughing: That sounds about right!


To the OP: I pressure wash the undercarriage of my vehicles on a weekly basis at least. I believe it is absolutely necessary!
 
Thanks everyone, I pressure wash as much as I can on the undercarriage. How about for customers does anyone do undercarriage cleaning or offer it ?

Yes I do. Been accused of going overboard under a car. My thought is if you can see it then it gets cleaned. Hate folks that drive cars that run rims that you can see through and the wells and suspension pieces look like crap.
 
Salt put the last nail in the coffin for my Pathfinder's rear silencer. It fell off today. Salt does contribute to rust. I ordered a new Bosal cat back exhaust.

I like people whose cars are dirty as all he'll but the tires and rims always glisten. Seems stupid to me.

You mean the ones that the tires an rims are worth more than the car......

$3000 of tires and rims on a $500 car....

Don't forget the $2000 stereo on top of that....

Yet another reason not to live in NY. Though now even Atlanta isn't safe from ice and snow, I guess I'll be looking at Zillow for homes in AZ.

I have a 64 Impala from CA and you can tell by looking down the side of the car that it's not from New York.

They have to rewire the salt truck at least once during the winter to have rear lights........

Eastwood Road Salt Neutralizer Gallon

I've been using the "Salt Away" product. It helps rinse away salt, because salt is fairly inert and can't be easily neutralized.

Its popular with people who own boats, so at least its not snake oil. Whether it really contributes anything to car care remains to be seen.

I should say that it didn't seem to take off the sealant coat of Collinite I had on there, so you don't have to give up your overall protection to use it.
