Metal spring anti-rust technology

In daily life, we often see that although stainless steel does not rust, stains often appear on the surface. Stainless steel hardware springs are a bit more difficult than ordinary stainless steel, so some tips should be used to deal with them. Then other stainless steel products also have the same principle.
   Generally, the washing method is based on the surface condition, and we also need to pay attention to some specific matters.
   For example, when washing, please be careful not to scratch the surface. Avoid using bleaching ingredients, detergents containing abrasives, steel balls (brush roller balls), abrasive tools, etc., in order to remove the detergent, after washing, rinse the surface with clean water.
Labels and stickers, use warm water, weak detergent to scrub; dust and easy to remove scales, use soap, weak detergent or warm water to wash; binder components, use alcohol or organic solutions; surface pollution caused by rust, use Nitric acid (10%) or abrasive detergent for washing-Use special detergents to cause excessive rainbow patterns, caused by detergent or oil, use warm water detergent when washing.
Fat, oil, lubricating oil pollution, wipe dry with a soft cloth or paper, and then use neutral detergent or ammonia solution or special detergent to wash; fingerprints, use alcohol or organic solvents (ether, benzene), wipe with a soft cloth Wash with water after drying; rinse with water immediately after bleaching and acid attachment, soak in ammonia or neutral carbonated soda aqueous solution, and then wash with neutral detergent or warm water.
Welding discoloration by heat, wash with 10% nitric acid or hydrofluoric acid solution, then neutralize with ammonia water and carbonated soda light solution, and then wash the stainless steel spring with water–specially used for washing medicine; organic carbide is attached and soaked in hot neutral detergent or The ammonia solution is then washed with a weakly abrasive detergent, and so on.
  Using these methods to clean stainless steel products can try to ensure that the damage on the surface of the stainless steel is minimized, so that the stainless steel products look more comfortable and more comfortable to use.
