car wash foam gun:Basic process of car washing and misunderstanding of foam gun

First of all, let's introduce the basic process of car washing. The first step is to simply wash the whole car body with a water gun for the first time, holding a water gun in one hand and a water pipe in the other, so as to prevent scratches caused by friction between the water pipe and the car body surface. Wash the dust and dirty places on the car body. Here, it is necessary to keep the water column at a 45 degree angle with the car body, so as to prevent water splashing on the clothes when washing the car. This process lasts for 1-3 minutes. It mainly depends on the cleanliness of the car body. The time will vary.
 
The second is to apply foam, which requires the use of foam gun. Use foam to evenly cover the body with foam, so that the whole vehicle becomes snow-white. Note that the foam pipe and the car wash pipe should not be entangled. After the foam covers the car body, you can use the equipped towel and special brush or sponge for car washing to scrub the car body 360 degrees. Ordinary stains and dust can be quickly cleaned with a brush. The parts with stubborn stains need to be wiped with a towel. After the whole car body is wiped, you can wash the foam on the car with clean water. Generally, as long as the car is not too dirty, the whole washing process takes about 20 minutes.

Finally, wipe the water on the car body with a dry towel. If there are dead flies or bird droppings, spray them locally with special omnipotent water and wipe them with a towel for about 1 minute. Finally, check the car body as a whole to ensure that it is cleaned in place, and then the whole car wash is completed.
