How to deal with the oily film after wiper wiping?

[VonJocelyn]

Engine exhaust forms an oily film on the glass. Here are the specific details: 1. After the wiper blade has been used for a period of time, the rubber begins to age and harden. The pressure from the back cannot flatten the wiper blade, resulting in a gap of about 10CM in the middle of the blade, which prevents the rainwater from being wiped clean. 2. Because the temperature of the front windshield is too low, the freezing point of the windshield washer fluid is insufficient. Here are some methods to remove the oily film: 1. Use baking soda to remove the oily film. Alternatively, you can use high-proof liquor or alcohol. Soak a soft cloth with it and wipe the front windshield of the vehicle. The volatility of alcohol helps to remove the oily residue. 2. Use hot water to wipe the windshield. Oily residues have reduced adhesion to surfaces in high-temperature environments. Therefore, soaking a towel in hot water and wiping the window is also effective.
