How To Clean Screws So That They Won’t Rust?

If a screw is installed for a long time, its appearance will be slowly plated with a layer of yellow rust, then how to remove rust from screws? After the screw is used for a long time, it also needs to be cleaned. Then how do clean screws so that they will not rust? As a professional fastener manufacturer, Xinchi Fastener Company will show you how to clean screws with many years of experience in the fastener industry. When washing screws, please pay attention not to scratch the surface, and avoid using bleaching ingredients and detergent containing abrasive, steel wire balls, grinding tools, etc. In order to remove the washing liquid, when the washing is finished, the surface of the screw should be washed with clean water.

If the screw has a binder component on the surface, you can use alcohol or an organic solution to clean the screw.

Alcohol or organic solvents (ether, benzene) should be used if the screw has fingerprints on the surface. Dry with a soft cloth and wash with water.

If the screw is heated and discolored, it can be washed with 10% nitric acid or hydrofluoric acid solution and then neutralized with ammonia, carbonated soda, and light solution, and then washed with water.

If the screw has organic carbides attached to the surface, it can be soaked in a hot neutral detergent or ammonia solution and washed with a detergent containing a weak abrasive.

If there is dust and easily removed dirt on the surface of the screw, you can wash it directly with soap, lotion, or warm water.

If the surface of the screw is contaminated with fat, oil, or lubricating oil, you can use a soft cloth or paper to dry it with neutral detergent or ammonia solution, or special washing drugs to wash.

If there is rust caused by contaminants on the surface of the screw, then it can be washed with nitric acid (10%) or abrasive detergent – use special detergent to clean CD screws.

The rainbow pattern on the surface of the screw is excessive, which may be caused by the use of detergent or oil. When washing, neutral detergent should be used with warm water.

If there are labels and film on the screw surface, you can use warm water or weak detergent to scrub.

If there is bleach or acid on the surface of the screw, rinse immediately with water. First, soak the screw in ammonia or neutral carbonic acid soda solution, then wash with neutral detergent or warm water.
