Chewing gum itself will corrode car paint. After a long time, there will be many spots on the car, and then the gloss of the car paint will decrease! These spots are on the glass, which is difficult to remove when using the wiper, and it will also lead to the deformation of the wiper.
Raw rubber on trees is not easy to wash. Can be removed with a soft cloth dipped in a small amount of alcohol. It's not good for car paint after a long time, and it may need polishing. There is a street tree called "Shunk", which secretes a lot of mucus in spring, autumn and winter every year. If the car is parked under the Shunk, there will be a thick layer of paste to seal the car, and it will be dirty when it meets dust, which is difficult to remove. Must be washed with big water.
