How can a car wash store do business well even on rainy days?

Then we must first solve the problem of drivers: "Why do I have to wash my car on rainy days?" I believe that most people who drive choose not to wash their cars on rainy days because after washing, they still look the same after driving for a while. In other words, sometimes when the car is not very dirty, God is playing the role of "helping wash the car".

So, very few people have the idea of ??washing their cars on rainy days. We can analyze several situations where a car wash may be necessary. First, the car is really dirty and must be washed; second, I am almost home and when I am not going out, I wash it first. At this time, I must be nearby or at an underground car wash (Shanghai now has many underground parking lots) There are car washes everywhere).

After clarifying this, as others have said, if you want them to wash the car on a rainy day, unless they feel they are taking advantage, then go to the car wash early. Necessary deep discounts may be a better option.
