Birds eat sand. That's (probably most likely) why scrubbing off bird droppings causes scratches.
I hadn't thought of that, since the stones in their gizzard are usually coughed up, but it makes sense some would go all the way down.

I usually wet a cloth with solvent (usually water) and let it lay atop the stain and soak in before wiping off lightly (and squishily).

Most stainless isn't 100% perfect, and contains small imperfections where the chromium didn't get distributed, and so you get tiny rust spots in the unprotected iron.

Paint also has a very similar problem. I am not one to care about little defects on a work truck, so long as most of it holds up fine.

I always wax my vehicle monthly . It leaves a thin layer of wax to prevent the bird poop from contacting the metal surface for a easy clean up.
