Could be way off, but it looks like rail dust (iron dust = rust) to me. Do you live near a railroad?

Best to remove. I'd take through a drive-through car wash and get the wash that under sprays under the car bottom. (Usually the cheapest will).

Although I don't live near a railroad, it's possible to be rail dust because I drove a long distance last week.

Thanks for the advice! Just did a car wash 10 days ago, Ontario's winter is terrible ?

Thanks. Will ask the dealership to check when I do The Work the next time. Do you think the brown spots are rust? If so, then it seems the rust-proof did not cover that part...

Hi guys, I recently found that there are some brown spots on the chassis, is this normal? Should I pay attention to it? It is a 2021 ford edge sel awd. Thanks in advance.
