Mechanical Problems & Technical ChatIf you've got a problem you just can't figure out, a noise you can't diagnose, or a check engine light that won't go away, ask about it here!
No, unless you've got more than just dirt on it. My car gets staining from dirt when I drive on dirt roads but the clear coat has long since worn off and the car is white, further adding to the problem.
It looks like it's just pollen stuck to the outside, although this is not really the season for pollen. My only experience with corrosion and enamel is with teeth.
unless there's acid rain embedded in the soil and pollen, then it will eat away at your paint and metal causing frame damage..........j/k, no, it's fine, I've went about 6 months without washing it.
I had a friend who lived near a gravel pit where they made concrete. He rarely washed his car and his paint was in horrible shape. It really matters where you live, how often you need wash your car.
