Will Car Wax Be Washed Away by Rain?

[DelWilliam]

No. Here is the relevant introduction: The wax itself is waterproof and can protect the car paint. The purpose of waxing is to make the car less susceptible to erosion from external dust and acid rain, thereby providing a certain protective effect on the paint and surface, helping to maintain the gloss and smoothness of the paint, and minimizing external pollution and erosion. Generally, the wax will naturally evaporate under sunlight in 1 to 2 weeks. However, the foam or detergent sprayed during car washing can be very harmful to the wax, almost washing it off in one go. Frequent washing can also remove the gloss of the paint, so it is recommended to wash the car with clean water from top to bottom to avoid damaging the paint.
