What to Do When the Wiper Blades Leave an Oily Residue?

[LaAlessandra]

Solutions for unclean wiper blades: 1. The longer a car is used, the more likely oil, car wax, and dust will accumulate in the tiny pores, forming an oily film layer. This is the main reason why many older cars cannot be cleaned properly. 2. If there are only slight stains on the glass, they can be wiped clean with a towel by applying some force. 3. After applying a protective agent, the transparency of the glass will significantly improve. It can also fill in the tiny pores on the glass, making it smoother and forming a protective layer.
