What are the yellow spots that fall off the car body every day?

The yellow substance that falls off the car body every day is insect excrement. Rinse with clean water: Before it hardens, you can wet it with clean water and rinse it off, then use a towel with cleaning solution to wash it. Clean with acidic solution: You can use an acidic solution for cleaning, such as common white vinegar. White vinegar is an acidic liquid that can effectively dissolve cement. Pour white vinegar onto the cement attached to the car, wait a few minutes for the cement to soften, and then it will be easy to clean. Generally, multiple cleanings are needed, and you should be careful during the process to avoid damaging the car paint. Use a special cleaner: Apply the special cleaner to the yellow spots and let it soak for a while, then wipe it clean with a cloth.
After driving for so many years, I often see yellow spots on the car body, which is quite annoying. The common causes of these yellow spots are tree sap or resin. For example, if you park under a tree and the tree sap drips down and isn't cleaned in time, it will turn into hard yellow spots. Or, in industrial areas, iron dust falls on the car, and when washed by rain, it forms rust spots that smell metallic. Bird droppings contain acid, and if not wiped off promptly, they can also stain the paint yellow. I've tried many methods; ordinary car wash water can't remove these stubborn spots. The best solution is to buy specialized bug and tar removers or iron particle cleaners, spray them on, and scrub. Then, apply wax periodically for protection. For prevention, try to park in shaded areas but away from trees, clean the car frequently to keep it spotless, and avoid letting rainwater accumulate for long periods. Maintaining your car this way keeps the body shiny and saves money on repairs at the shop.
My car is parked in front of my house, and the small yellow spots appearing daily worry me, especially with kids touching them constantly. These yellow stains are mostly tree sap dripping from trees or iron particles from roadside dust, becoming harder to remove in hot weather. To protect the car paint, I usually avoid parking under trees and rinse off any spots with water before drying them at home to prevent them from setting. I regularly wash the car with mild car shampoo and apply wax to shield against contaminants. Environmental factors can't be ignored—nearby factories or sunny days after rain can easily cause spots, so I schedule regular professional car washes for deep cleaning, keeping the car shiny without harming my family's health. Sticking to these small habits saves both money and hassle.
I noticed yellow spots on my car shortly after buying it and learned from a friend that it might be tree resin left uncleaned, or urban dust and rainwater corroding the paint. Dried bird droppings can also leave marks. I tried wiping it with car cleaning spray, and the earlier you deal with it, the better the effect. Be careful not to use strong acid cleaners randomly to avoid damaging the car.
