Precautions for using wiper:
1。 Keep sth clean
If there are stripes on the windshield of the wiper, it means that the wiper blade is dirty. Spray a certain amount of alcohol on the towel and then wipe it on the dirty and residual dirt. Cleaning once a month can improve the working effect of wiper.
2。 Check rubber
There is a harsh sound on the windshield. It is likely that the rubber of the wiper blade is hardened, worn and cracked. If the wear is not particularly serious, the owner can grind the uneven surface with sandpaper.
3。 Avoid exposure
When the vehicle is not used for a long time, try to park it in a cool place. Some car owners park their cars outdoors at will and directly expose themselves to the sun. Wiper blades are rubber products, and temperature is their number one public enemy, which makes the possibility of qualitative change greater.

BMW X3 sound insulation refit
Sound insulation reconstruction of BMW X3;
Sound insulation part: four-door sound insulation, cockpit floor, trunk floor and rear wheel radian, front and rear fenders, hood sound insulation.
Sound insulation materials: high-energy sound insulation, high-energy low-frequency sound absorption, and Dr. Wang An's silencing.
The main function of cockpit floor sound insulation is to deal with high-speed and low-frequency vibration of sheet metal, making the cab more quiet and comfortable.
Step 1: the inner layer of the door is treated with sound insulation and shock absorption, and the sound insulation material is Danone Sound Insulation King;
The second floor: the cockpit floor is sound-proof and shock-absorbing, using environmental sound-proof king;
The third layer: eliminating low-frequency vibration, made of high-energy top-level low-frequency king.
The fourth floor: air absorption treatment, there is still a small amount of noise after vibration reduction, and the noise from the cockpit floor is further reduced by the third floor sound absorption treatment, making the driving environment more quiet and comfortable.
The front and rear wheel arcs and fenders absorb impact and sound insulation. This is the most common place for chassis noise. Abnormal sound generated by shock absorber, friction and impact noise generated by tire and pavement, gravel, sheet metal parts, etc. It is easy to be introduced into the cockpit through the vibration of the front and rear wheel arcs and fenders. These parts can obviously reduce the noise generated by the pavement and shock absorber after the shock absorption and sound absorption construction, and the effect is very obvious.
Step 5: Sound insulation and shock absorption of range hood. The engine is the main noise source of the car itself, and it is also the noise source closest to the driver. Therefore, the sound insulation of the range hood can effectively reduce the noise impact and protect the paint surface.
