To prevent possible damage to the paint, bird droppings should be removed as soon as possible. To remove them, place a wet cloth over the stain and let it sit for ten to thirty minutes. Don't scratch it off with a fingernail because this can scratch the paint.

I agree, Five Speed. Actually, anything that sits on your paint can cause harm and should be removed as quickly as possible. You never want to scratch anything off the surface of the paint, but rather, like Five said, ease it off with a wet cloth.

This is absolutely true. I have the experience of parking my car below a concrete structure with paint on it. Rain fell and some of the paint particles dripped on a spot on my car. I was in a hurry due to the drizzle and forgot about the paint particles. They stuck and hardened. It took time to remove them. I was almost tempted to scratch them off. Wiping them out while it was wet could have done the job.

That scenario really helps state the case for keeping a good layer of wax on your car throughout the year, and just staying on top of keeping the body clean.

I agree, but the reality is that I'm not out there watching my car 24/7. Fortunately, though, it's never been an issue with my vehicle, knock on wood. When it's happened, I've just cleaned normally.

Bird droppings come when you're around birds --- residential areas with birds, parks with birds ... and wildlife. I have a bird poo on my car before and I took it for granted. Man, it hardened and stuck to the car. It doesn't take a lot of muscles to wipe them away the first moment you notice them.
