I went with my daughter to a doctor and had to leave a car on the street. After 2h birds loved to poop on my car. I have stains after bird dropping. I've removed it right away, but stains are there

I took it to car wash, but nothing helped. Any advice?

 

Usually a good wax will take it out. Even a spot wax like 'Mother's Quick Detail' will work usually.

 

get yourself a good polishing compound, and a polisher.

These are the products I use on my car
