Chefu is one of the earliest brands in China's car care industry. Since its establishment in 1993, it has more than 10 subsidiaries and seven major auto supplies production bases, and its products have been the first in domestic sales for 19 consecutive years. In addition, Chepu is the drafting unit of national standards such as "Throttle Cleaner" and "Engine Lubrication Cleaner". The car servant rain protection agent is canned, similar to Goodway, but the price is half cheaper than Goodway, about 22 yuan a can, because it does not contain fluorine, so the water displacement effect is only good when it is first used, the durability is not strong, and it needs to be used frequently.
