Does bird droppings sticking to the car for a few days have any impact?

[McDonovan]

A small amount of bird droppings sticking to the car for a few days generally has no impact, but it is recommended to wash it off as soon as possible because bird droppings are acidic. If a large amount of bird droppings remains on the car's paint surface for an extended period, it can cause severe corrosion and is also unhygienic. If bird droppings have been on the car for more than ten days and have hardened, the paint may already have been damaged. However, avoid using sharp objects to scrape it off to prevent further damage to the paint. The correct approach is to use a bug and tar remover along with a soft cloth to wipe it off, then visit a repair shop or 4S store for restoration. To prevent bird droppings from landing on the car's paint surface, try to avoid parking under power lines or trees when parking. You can purchase a car cover or park the car in an indoor parking lot or a sheltered area.
