It is recommended that you change your wiper blades every 6-12 months.

Don't put old wiper blades into plastic recycling box. Wiper refill and rubber are harmless material,metal material is recyclable, rubber material is non-recyclable, so it is better to put old wiper blades into residual garbage.

The quality of the wiper mainly depends on whether it is clean, such as whether there is residual water mark, whether there is noise, or whether the wiper strip is beating. If the above problems occur, do not rush to replace the wiper, first check the use environment and then make a judgment.
