How to clean car special screws

Although the environmental sanitation situation of the special screws for automobiles is not ideal, before the screws are sold to the customers, the customers are still picky about the appearance of the special screws for automobiles. If the screws taken out are dirty and overflowing with oil, they will be given to others. The first impression is relatively poor, and the price in the eyes of customers is not high, so screw cleaning is an indispensable detail.

     However, since screws are inevitable to deal with various smooth oils and emulsifiers in the process of processing, and these oil stains are more difficult to clean, then if you want to clean the appearance of the screws, what good methods can be used? What achievements should we pay attention to during the cleaning process?

     First of all, the most important thing about automotive screws is the thread, and the thread is more likely to be damaged by sharp materials, so you must be more careful when cleaning the screw thread. Do not use metal balls or other grinding tools to clean the threads wanton. Once the thread is destroyed, the entire screw will be scrapped.

     Secondly, the main stains on the car screws are oil and dust. The characteristics of these two kinds of stains are different. The former is more troublesome to clean, and the water solubility is very low, and the second is easier to clean. Therefore, we have to distinguish between screws with different sanitary conditions. If the main purpose is to remove oil, it is recommended to use a neutral detergent to wipe them. Among them, the damage of chemicals to the screws is relatively small, and it does not hurt the hands too much.

     Some migrant workers do not understand the situation and use bleaching powder or detergent. This is not allowed. Because the screw detergent sold by the stainless steel screw manufacturers on the market contains abrasive ingredients, although it is easier to clean, it only needs to be fine. If you look at it, you will find that the surface of the screw will be scratched with many fine lines.

     If the main purpose is to clean the gray layer on the screw, the method is much more complicated. It only needs to mix hot soapy water with a large amount of detergent. Initially, regarding the special stains of car screws, such as rust stains, ordinary cleaning agents are not clean. It is best to use a nitric acid solution with a concentration of about 10% to wipe.
