How to maintain a stainless steel thermos cup after polishing?
After polishing, the surface of a stainless steel thermos cup will become smoother and more beautiful, but it also requires more meticulous maintenance to maintain its appearance and performance. Here are some specific maintenance methods and suggestions:
Cleaning method
Use neutral detergent: When cleaning a polished stainless steel thermos cup, it is recommended to use a neutral detergent and avoid using alkaline or acidic detergents to avoid corrosion on the surface of the cup.
Soft cloth wipe: Use a soft cloth or sponge to dip in detergent and gently wipe the inside and outside of the cup. Avoid using hard tools such as steel wool and hard brushes to prevent scratching the polished surface.
Regular cleaning: The thermos cup should be cleaned in time after each use to avoid residues from adhering to the surface of the cup for a long time, causing stains or corrosion.
Drying treatment
Thorough drying: After cleaning, be sure to thoroughly dry the thermos cup, especially the lid and sealing ring, to prevent moisture residue from causing odor, mold growth or corrosion.
Dry naturally: You can turn the thermos cup upside down and dry it naturally. Avoid high temperature drying to avoid affecting the insulation performance.
Avoid corrosion
Avoid contact with corrosive substances: Although the corrosion resistance of the polished thermos cup has been improved, it should still avoid contact with corrosive substances such as strong acids and alkalis, such as long-term storage of carbonated beverages, juice, etc.
Deal with rust spots in time: If you find red spots similar to rust on the surface of the cup, soak it in warm water and diluted vinegar for 30 minutes, and then wash it thoroughly.
Avoid collision
Use with caution: The surface of the polished thermos cup is smooth, but it is still necessary to avoid violent impact or falling to avoid deformation of the cup body or surface scratches, affecting the appearance and insulation effect.
Regular inspection
Check the sealing: Regularly check the sealing ring and cup lid of the thermos cup to ensure that they are intact to maintain good sealing performance.
Check the insulation performance: If the insulation effect is found to be significantly reduced, it may be that the vacuum layer is damaged. It is recommended to contact the manufacturer for inspection or repair.
Through the above maintenance methods, the service life of the polished stainless steel thermos can be effectively extended, maintaining its good appearance and thermal insulation performance.
