How to prevent corrosion in a thermos cup after polishing?

Although the corrosion resistance of the polished stainless steel thermos cup has been improved, some measures still need to be taken to further prevent corrosion. The following are specific methods:

Avoid contact with corrosive substances
Avoid corrosive liquids: Try not to put corrosive liquids such as strong acids, strong alkalis, carbonated drinks, juice, milk, dairy products, alcoholic drinks, etc. in the thermos cup for a long time. These liquids may react chemically with the inner wall of the thermos cup, causing corrosion.
Timely cleaning: If the above liquids are accidentally filled, they should be drunk as soon as possible and thoroughly cleaned to avoid long-term liquid residue and increase the risk of corrosion.

Correct cleaning and drying
Use neutral detergent: When cleaning the thermos cup, use neutral detergent and avoid using strong cleaning agents such as alkaline bleach and chemical rags to avoid scratching the surface of the cup and affecting its corrosion resistance.
Soft cloth wiping: Use a soft cloth or sponge dipped in detergent to gently wipe the inside and outside of the cup body. Avoid using hard tools such as steel wool and hard brushes to prevent scratching the polished surface.
Thoroughly dry: After cleaning, be sure to thoroughly dry the thermos cup, especially the cup lid and the sealing ring, to prevent residual moisture from causing odor, mold growth or corrosion. You can turn the thermos cup upside down and dry it naturally, and avoid using high-temperature drying.

Avoid collisions and drops
Use with caution: The surface of the polished thermos cup is smooth, but you still need to avoid violent collisions or drops to avoid deformation of the cup body or scratches on the surface, affecting the appearance and insulation effect, and also reducing its corrosion resistance.

Storage environment
Avoid moisture: When storing the thermos cup, choose a dry and ventilated place and avoid placing it in a humid environment to prevent the cup body from getting damp and rusting.
Avoid high temperature: Do not expose the thermos cup to high temperature for a long time, such as near a fire source or under strong light, so as not to affect its material properties and reduce corrosion resistance.

Regular inspection
Check the cup body: Regularly inspect the cup body, cup lid, sealing ring and other parts of the thermos cup to check for scratches, rust or other damage. If you find any problems, take timely measures, such as soaking the rust spots in warm water and diluted vinegar for 30 minutes, and then fully cleaning.
Check the sealing performance: Check the sealing performance of the thermos cup regularly to ensure that the cup lid fits tightly with the cup mouth to prevent moisture from penetrating and causing corrosion.

Through the above measures, you can effectively prevent the polished stainless steel thermos cup from being corroded and extend its service life.
