Four main points that should be paid attention to in car washing

Car washing environment is the foundation.

Many people like to wash their cars on sunny days, thinking that cars can work faster with sunshine, but not all sunny days are suitable. Washing cars in the hot sun will do harm to their cars.

When washing a car in the hot sun, the convex lens effect formed by water droplets will cause local high temperature on the top of the car paint, and the car paint will lose its luster after a long time. So it's best to wash the car under cover. If you can't guarantee it, you'd better choose cloudy or sunny morning and evening.

The order of car washing can't be chaotic.

The correct order of car washing should be from top to bottom, washing first and then washing.

The first step is to wash the sediment with slow water to wash away conspicuous dust, which can largely avoid scratching the car paint when washing the car later.

Step two, spray car wash liquid. The car wash liquid should be neutral, and it will not hurt the car paint when cleaning.

The third step is to clean the stain. Try to choose soft objects to clean the stains on the car body surface, such as sponge soft towels.

The fourth step, rinse to dry, which is easily overlooked. However, if there is water stain, it is easy to form water stain on the surface of the car paint, which is harmful to the car paint in a certain concentration under the sunlight, so the drying step cannot be omitted. Finally, clean the tires. Pebbles and particles on tires can be cleaned with a brush.

Remember the way to wash the car.

Just as it is easy for people to get flu by bathing directly with cold water in a hot and dry state, it is also easy to have problems by washing directly with cold water in a hot car. The working temperature of automobile engine is usually above 80℃. If the water gun is directly used for flushing, the cylinder head and other important parts of the engine will be deformed due to thermal expansion and cold contraction, resulting in poor sealing and water leakage, which may lead to serious damage to the engine after long-term use.

So, if the temperature inside the car is too high, find a cool place to turn off the engine and let it cool down naturally. It's not too late to wash it when the temperature drops.

In addition, different ways should be taken to deal with different stains on the car. Just as we need to "prescribe the right medicine" for acne and redness on our face, so does car washing! Different stains need to be treated in different ways. Stubborn stains such as bird droppings and shellac will become "sharp tools" for scraping paint without special treatment.

To remove them, you need to spray ordinary neutral body paint cleaner on the stains, and then attach a wet paper towel or car towel, so that it can be easily wiped off after softening. When cleaning stubborn water stains, directly wipe the water stains with a sponge filled with detergent, and then clean them with clear water.

Car washing tools are not casual.

Many people think that the more foam the detergent scrubs, the stronger the cleaning power. Actually, this is a misunderstanding. For car cleaners, foam can be mixed with washing powder. Washing powder is an alkaline detergent, which will seriously damage the luster of car paint if used for a long time.

Therefore, the car wash should choose a special car wash water wax. The key performance of this special car wash liquid is lubrication, not so-called rich foam. It can improve the gloss and the lubrication effect is good, so we don't have to worry about impurities scratching the car paint when we wipe it.

In addition to washing liquid, you should also pay attention to washing a bucket of water and a rag during car washing. Except for new cars and newly polished cars, as long as you look carefully, you will find that most of the car paint surfaces have many irregular tiny scratches, some of which are caused by improper car washing.

The things handled by car washing are mainly dust in the air and fine sand and gravel on the road. The main component of sandstone is calcium carbonate, and the main component of sandstone is silicon dioxide. The hardness of these two substances is obviously higher than that of paint surface. If you are scratched by sand and gravel, the paint surface will be damaged.

If the car is washed with the same rag all the time, in the initial foaming process, sand and gravel will be wrapped in the rag and painted with this irregular abrasive cloth. The consequences can be imagined. It is strange that the "face" of the car will not be scratched. Therefore, try to choose professional car wash towels and honeycomb car wash sponges for car washing. These tools can absorb dust and sand to reduce the damage to car paint.

Washing a car should be like washing a face. You should choose the right temperature, choose soft towels, use mild products and pay attention to the operation methods.
