Car paintwork is not damaged by bird dropping 'acidity', according to a new study by vehicle care specialists Autoglym.
The study showed that the faded patches of paint left from droppings are actually the result of paint lacquer contracting, when it cools, and moulding to the hardened deposits' uneven texture.
In the summer sun, paint lacquer warms, and then it softens and expands, while bird dropping on the surface dries and hardens in the heat.
Upon cooling, the paint lacquer contracts and moulds to the bird dropping's texture.
The group said that car owners should remove bird droppings from bodywork as quickly as possible if they want to avoid the cost of repainting their vehicle on top of other expenses such as car insurance.
Paul Caller, CEO ofAutoglym, said: "It's a great shame when an otherwise fabulous-looking car is blighted with a tell-tale patch of dull paint.
"The only way to prevent the paint becoming noticeably tarnished is to carefully remove deposits as swiftly as possible."
