If you use it to wash the car, it is too particular. The car wash detergents used in car washes can be basically divided into three types: washing powder, detergent, and special car wash liquid. Some car owners went to the car wash shop and saw that the staff washed very seriously. The washing bubbles were flying all over the sky. The ability to "clean and decontaminate" was quite strong. The dirty car didn't seem to be in the air. After washing, it looked very clean from the outside. . If you want to know what the car wash shop is using to wash your car, you can pinch your fingers, sniff the bubbles, and wash the powder! Yes, some car wash shops use washing powder to wash cars.

The boss also revealed a discerning trick, that is, look at the hands of the car washer while washing the car.

A professional car wash shop will never spray with a high-pressure water gun as soon as it comes up. Generally, the first time must be fine water and slow flow, from top to bottom, the dust particles on the car will be taken away with water. If you use a high-pressure water gun from the beginning, it is equivalent to let the dust particles do "frictional motion" on the painted surface. Sometimes, in order to save trouble, the owner often washes the car in the roadside shop. Those who wash the car with a bucket of water, if you look closely, you will find that there is a lot of sand in their buckets, no different from cleaning the car with sandpaper. Some towels used in car wash shops are also eliminated from the hotel. Such towels look very new and white, but they are actually rough and hurt the car. Consumers reminded car washes and caring for cars Since the increase in urban water costs, car wash is no longer a separate income, and many car beauty shops and auto repair shops regard car washing as an auxiliary project. Some car owners drove the car to the garage. After the car was washed, the tires were out of breath. People know that they are stupid, but they can't understand the truth.

The tool for the car is usually a sharp-edged wire that is hidden on the cloth. It is understood that the car wash is divided into three parts: taking the water gun to wet the car is the first step; the second step is to wash the car wash; the third step is to scrub the car interior. When I was in the first two steps, I wouldn't start. When I cleaned the car, the people would all go around and the owner's eyes would be blocked. Then they started to get stuck. They usually choose the right side of the car, because the driver is on the left side of the car and also stands on the left side after getting off the car, so that the tire on the right side is not easy to be found, and the sound of the vacuum cleaner is very large, and the sound of the deflated sound can be masked. live.
