Moisture-proof sterilization

In winter, in order to keep warm, people rarely open windows for ventilation, which leads to a large number of bacteria quietly accumulating in the car. When the weather gets warmer in spring, they will wake up and breed wildly in the wet car, so the car must be fully disinfected this season.

Check the air conditioning system

First, check the cleanliness of the condenser and evaporator surfaces. If there is a lot of dust, you need to scrub it with a clean rag. Secondly, check the air-conditioning filter element, which is the filter screen of the air inlet of the car air conditioner, and it is the easiest to shelter evil people and shelter evil people. You can choose to go to the 4S shop to replace new products or use air conditioning cleaner for thorough cleaning.

Mildew-proof tip: Turn on the fan of the car air conditioner and keep it for about 3-5 minutes, which can effectively discharge the water in the air conditioner pipeline.

Clean the interior of the car

When changing "new clothes" in different seasons, you can use special interior cleaning agent to clean and disinfect the operation desk, door and other parts. However, it should be noted that never use substances with strong acidity and alkalinity for cleaning, which may damage the internal cortex, and pay attention to prevent electrical equipment such as audio, radio and CD from entering water.

Tip: Don't forget seat belts, foot pads, top handles, chair covers and other places that are easily overlooked!

Anticorrosion and anti-aging

"Anti-corrosion and anti-aging" is a knowledge point that car owners need to learn all year round after owning a car. Due to the special climate in spring, this problem needs special attention.

Automobile paint surface

There is more rain in spring, and the acidic substances in the rain will cause damage to the automobile paint, so special attention should be paid to protecting the automobile paint. You'd better paint your car during the seasonal maintenance. The simplest thing is waxing, and the more long-term and effective thing is to seal the glaze for beauty. No matter what method, put an invisible protective coat on your car to prevent the paint from fading and aging.

Check wiper

With the increase of seasonal rain, the road surface and sight are not conducive to driving in rainy days. If the wiper can't brush off the rain well, it will bring great danger to your driving safety, so check and maintain it more carefully. You can put the wiper switch at various speed positions, pay attention to whether there is vibration and abnormal sound of the wiper when working, check whether it keeps a certain speed when it rains at different speeds, observe the state of the wiper, and check whether the wiper strut swings unevenly or leaks. You can touch the rubber wiper blade with your fingers to check whether it is damaged and how elastic the rubber wiper blade is. If the wiper blade is aged, hardened and cracked, it should be replaced in time, preferably a boneless wiper blade.
