The average cost of passenger rear windshield is around 550 yuan (for reference only), but it should be combined with the brand awareness and quality of suppliers. Maintenance of glass is very important. Clean the glass properly when you have time, and try to use the specified window cleaning liquid. The cleaning solution contains components that can dissolve oil stains and improve the wetting interface of glass, which is beneficial to the maintenance of glass. Do not use the wiper when there are obstacles such as snow, ice, mud and dry bird droppings on the glass, otherwise it will damage the wiper blade, wiper motor and glass. Regarding the choice of film, there are various types of film on the front windshield, such as explosion-proof film and ultraviolet-proof film. It is suggested to use well-known brands of film as much as possible when conditions permit, otherwise the inferior film will not only fail to play its due role, but will cause security risks due to opacity and other reasons.
