I remember back in the day, things that I used to own people would say that the salt on the road in winter destroys the car and bikes for that matter.

What about modern cars - just driven a few hundred miles from up North, my modern car is covered in that nasty salt residue.

Should I be worried? Even on the alloys?

My choice was put it away caked in salt and nicely dry

or

wash it in the dark, minus 3 and put it away wet having done half a job

thoughts?

I would just give it a quick rinse (No actual washing or drying or anything) it to get the worst off and leave washing it till it's more appropriate.

Salt very much affects them!

just take a look underneath a 3 yr old scottish car and then take a look under the same model/age car but in SE england, what a difference.

All the main structure and paintwork will be fine but look at the brackets, hangers, nuts and bolts, suspension arms/disks/hubs, the salt really attacks all the unprotected metal (and alloys).

Paintwork should be fine as long as not chipped or scuffed.

Let me get this right some of you would wash your car every day throughout winter after the daily commute in the dark in sub zero.

Must make the road interesting the next day when the water has frozen over.

Ive seen 10 yr old Mercedes with visible rust and heard of RX8's with rusty sills. Driving the car in winter after the roads are salted is like washing it with salt water if it is wet, the salt will get into every little crevice and stay there even after a wash you cannot get it all out from underneath. Run your finger along the car and taste it, you can def taste the salt.

Not the daily driver, but whenever I drove my Elise in the winter I'd give it a quick once over when I got home.

The wheels in particular are showing signs of corrosion and need a refurb.

Is it acceptable just to lick the car? I am concerned about the hygiene implications of licking my fingers.

I was going to say lick lick the car, dont know what the neighbours would think of that. Also in this cold might get tongue stuck to car.

Correct me if I'm wrong, but isn't that the metal underneath the paint reacting (rusting) and releasing gasses, and causing the paint to distort rather than the paint itself reacting?

If I am correct, then this is your "Ambiwlans moment".

Just check out my rebuild thread in the Elise forum to see what sorta damage road salt does to even a pampered, seldom-driven car.

Horrid stuff.

Yes very much so

Check out most 10 year old Japanese imported cars where they use glycol (generally) V uk cars of the same age with Salt

This is a 12 year Jap Honda straight out of Japan, to honest this is about the same as 3 year old UK car
