Can you polish out bird mess marks?

It depends on how bad they are. We have seen them etch their way through to the primer, in which case, repair-and-repaint would be the only way to solve the issue. Bird's mess can be highly corrosive, and the corrosive compounds can soak deep into the paintwork where they continue destroying the binders in the paint every time moisture is re-introduced, re-activating the acid. This means it can continue destroying your paintwork months after you have washed it off.

We recommend washing off any bird mess as soon as you see it, using plenty of soap and water. It may be worth getting a product especially for neutralizing bird's mess and keeping it with your car with some wipes.

Having said all that, if the etching is light, we can polish out bird mess marks.
