Can dishwashing detergent remove oil film from cars?

Dishwashing detergent can remove oil film from cars, but it is not recommended as a car cleaning product. Generally, specialized oil film removers are used. Extended information about car cleaning is as follows: Introduction: Car cleaning refers to the cleaning of a car's exterior, which is a common task for every car owner or driver. In recent years, car wash shops have gradually become a hot investment project in many large and medium-sized cities. Classification: Car cleaning is divided into two types: regular cleaning and detailed cleaning. Regular car cleaning refers to traditional manual car washing and tunnel car washing. The other type is detailed car cleaning technology, which involves both interior and exterior cleaning, providing a more thorough and cleaner result compared to traditional car washing.
Last time I tried using dish soap to clean the oil film on the windshield, but the result was really unsatisfactory. Dish soap is mainly for degreasing and works well on kitchen grease, but automotive oil film is a mixture of exhaust fumes, tree sap, and dust, which is extremely sticky. After cleaning with dish soap, it may look clean at first, but the next day when the wipers swipe, it smears again. What's worse, dish soap is too alkaline and can wash away the hydrophobic coating on the glass surface, causing the wipers to make a creaking noise when the car is parked under trees. Now I use a specialized oil film remover spray. I spray it on, wait for two minutes, then scrub in circles with a sponge, and the oil film is basically gone without damaging the glass. The kind sold at gas stations for around ten bucks works just fine—much more reliable than dish soap.
