Does oil film cleaner damage glass?

[VanJoy]

Oil film cleaner does not damage glass. 1. Causes of oil film formation: After prolonged use of a car, tiny pores develop on the windshield. During driving, impurities and vehicle exhaust fumes in the air enter these pores, gradually forming an oil film over time. The oil film refracts light and is difficult to remove, affecting visibility and compromising driving safety. 2. Alternative methods: Toothpaste can also remove oil film. Toothpaste contains fine abrasive particles that, when applied to the glass and rubbed, can polish away the pores on the glass, thereby eliminating the oil film. If the oil film reappears after some time, it's necessary to check if the wiper blades are contaminated with oil. If the wiper blades aren't thoroughly cleaned, cleaning the glass will be ineffective. The wiper blades should be cleaned promptly, and replaced if necessary.
