What to Do When Stains on the Car Won't Come Off?

Clean the lower part of the vehicle. When cleaning the lower part of the vehicle, please wear rubber gloves. Follow-up Treatment If water accidentally splashes onto electrical components, dry the water with a dry cloth or blow it clean with compressed air, and remove any moisture inside the distributor cap.
I noticed that stains are particularly difficult to remove when washing my car, especially tree sap and bird droppings, which require professional cleaners. For tree sap, spray a bug and tar remover, wait five minutes, and then gently wipe it off. For bird droppings, first cover them with a wet cloth to soften for half an hour before rinsing. Brake dust on the wheels is best treated with an iron remover—spray it on, and when it turns purple, rinse it off. Don’t scrub hard water stains; try a vinegar-water mixture instead, which works well but shouldn’t stay on the car for too long. For sticker residue on the paint, use essential balm, and the adhesive marks will wipe right off. Remember to wear gloves when washing your car to protect your skin. Regular waxing keeps the paint smooth, making stains less likely to stick, so each wash becomes much easier.
My car often gets covered in tree sap when parked under trees. The car wash shop recommended a method: first spray pre-wash foam to soften stains, then use a high-pressure water gun to rinse off large particles. For stubborn stains, gently rub with detailing clay and lubricant, and the car body will become smooth immediately. Bird droppings should be dealt with quickly, as they can corrode the paint over time. Removing rust from the rims is particularly troublesome, but a dedicated cleaner wipes it off easily. For dust in the air vents, use a soft brush dipped in soapy water to clean slowly. Remember not to use laundry detergent for washing the car—it's too alkaline and damages the paint. After switching to a pH-neutral car wash soap, my car's paint became much shinier. Waxing once a month is very useful, as it makes stains less likely to stick.
