Is it necessary to buy a wiper hole protective cover?

If you often park under a tree, it is necessary to buy it, because this kind of protective cover can effectively prevent the fallen leaves from falling into the hole and getting stuck when starting the wiper. It's useless not to be under a tree for a long time, except where the leaves will fall.

The so-called wiper is a tool to simply clean the front glass of a motor vehicle in order to prevent rain and other pollutants from affecting the line of sight. There are roughly two types of wipers. One is the traditional intermittent wiper, which is the most common wiper. There are three or four sections, which are adjusted by the driver according to the rain and sight. The other is the rain bead induction type, which is mostly used in mid-to high-end models. A good wiper must be heat-resistant, cold-resistant, acid and alkali-resistant, corrosion-resistant, able to fit the windshield, reduce the burden on the motor, have low noise, strong water repellency, and be soft and scratch-free on the windshield. Can make your vision clear. Maintenance personnel suggest that in order to ensure your driving safety, it is best to replace the wiper once a year.
