从原理来看，砂纸打磨的方法对于雨刮片橡胶条老化所造成的清洁效果降低情况很好用，因此当我们发现雨刮器刮不干净玻璃时，要判断其原因。如果是雨刮器在使用时发抖、异响，有可能是安装过紧或者雨刮臂的位置和角度有问题，这时需要去的店里进行调整。
From a principle perspective, the sandpaper polishing method is effective in reducing the cleaning effect caused by the aging of the rubber strip of the wiper blade. Therefore, when we find that the wiper cannot clean the glass, we should first determine the cause. If the wipers tremble or make abnormal noises during use, it is possible that they are installed too tightly or there is an issue with the position and angle of the wiper arms. In this case, it is necessary to go to a professional store for adjustment.
如果雨刮片胶皮表面出现严重损坏老化，甚开裂等情况，这时候必须更换雨刮片。
If the surface of the wiper blade rubber is severely damaged, aged, or even cracked, it is necessary to replace the wiper blade at this time.
如果外观没有问题，但是雨刮片的上下总有一些部位刮不到，这时需要检查是不是雨刮已经变形，上下端翘起来，不能完全贴合在玻璃上，如果变形严重则需要更换。
If there is no problem with the appearance, but there are always some parts of the wiper blade that cannot be scraped, it is necessary to check if the wiper has deformed, the upper and lower ends are warped, and cannot fully fit on the glass. If the deformation is severe, it needs to be replaced.
当然如果以上三点都不属于，那我们就确定为雨刮片可能由于腐蚀老化造成工作效果退化，虽然可以正常使用，但是清洁效果已经大打折扣。我们也通过这几点来寻找符合要求的测试车辆。
Of course, if none of the above three points belong, then we determine that the wiper blades may have degraded their working performance due to corrosion and aging. Although they can be used normally, their cleaning effect has been greatly reduced. We also use these points to find test vehicles that meet the requirements.
2：确定测试车辆
2: Determine test vehicle
我们从同事中搜集了几台反应雨刮片不好用的车，通过实验发现这些车多多少少都遇到了一些雨刮片的问题。
Firstly, we collected several cars from our colleagues who reported that the wiper blades were not working properly. Through experiments, we found that these cars encountered some problems with the wiper blades to some extent.
通过观察测试车辆的现象，其中一台雨刮的工作效果确实不太好，虽然没有异响和明显的变形和老化，但是刮完后玻璃上会残留比较明显的印记，符合我们的测试要求，今天的测试就从它开始。
By observing the phenomenon of the test vehicle, it was found that one of the wipers did not work well. Although there were no abnormal noises, obvious deformation or aging, there were still obvious marks on the glass after scraping, which met our testing requirements. Today's test will start from it.
3：购买工具
3: Purchase Tools
其实这个小窍门需要用到的工具非常简单，清水一瓶，砂纸一张。这里需要说一句，市面上砂纸分为很多种，粗细程度也不一样，这里建议用细砂纸进行雨刮翻新，避免粗砂纸对表层伤害过度，反而会影响雨刮片的使用。
In fact, the tools required for this tip are very simple, one bottle of water and one piece of sandpaper. It should be noted that there are many types of sandpaper available on the market, with varying degrees of thickness. It is recommended to use fine sandpaper for wiper refurbishment to avoid excessive damage to the surface caused by coarse sandpaper, which can actually affect the use of wiper blades.
