How to safely remove bird droppings from your car - without permanent damage to the paintwork

Bird droppings on a freshly washed car body are a common occurrence. However, this seemingly harmless stain is not just an aesthetic problem, it can also cause permanent and expensive paint damage if not removed in time.

While it's understandable that drivers want to remove it immediately, expert warning is that panicking or wiping it off with a paper towel can do more harm than good.

The solution to removing even dried-on deposits does not require expensive chemicals, but only two ingredients that most people have at home – warm water and baking soda, Express.co.uk reports.

Why is bird droppings dangerous?

Bird droppings contain uric acid, which makes them very acidic and corrosive. With a pH value of around three to four, they can quickly corrode the protective layer of paint and then the vehicle's paint itself, reports Net.hr.

The process of deterioration is further accelerated by the sun and high temperatures. When the varnish heats up, it becomes more porous, allowing the acid to penetrate deeper layers more easily. The consequences can be dull spots that cannot be polished out, discoloration, and even peeling and cracking of the varnish.

The biggest mistake drivers make is trying to remove dried bird droppings dry. Bird droppings often contain tiny grains of sand, gravel, or seed residue that act like fine sandpaper when rubbed off, leaving scratches on the paintwork.

How to safely remove a stain

Warm water and baking soda are sufficient for safe removal.

Pour about a liter of warm water into a spray bottle and add four tablespoons of baking soda. Shake well to completely dissolve the soda. If desired, you can add a drop of dishwashing detergent to help the solution stick to the surface.

Spray the resulting mixture liberally directly onto the dried bird droppings and leave to sit for about ten minutes. The baking soda will neutralize the acid and soften the deposits.

Then gently wipe the stain with a clean microfiber cloth soaked in warm water, without applying too much pressure or rubbing. If the stain does not disappear on the first try, repeat the process instead of applying force. You can also rinse the residue with a gentle stream of water, then dry the surface with the clean side of the cloth.

Prevention is the best protection

The best way to protect your paint is to wax your car regularly, as wax creates a protective layer that slows down the action of acid and makes it easier to remove dirt.

It is also advised to avoid parking under trees, public lighting poles, and power lines, where birds most often stay.

If you notice fresh bird droppings, remove them as soon as possible with a damp cloth, before they dry. A quick response can prevent permanent damage and preserve the appearance and value of your car, reports N1.
