To maintain a stainless steel bathroom cabinet, you should follow these steps:

Clean regularly: Wipe the surface of the cabinet regularly with a damp cloth to remove any dust or debris that may have accumulated. This will prevent the buildup of grime and other substances.

Use mild cleaning solutions: When cleaning, use mild solutions such as soapy water or a mixture of vinegar and water. Avoid using harsh chemicals or abrasive cleaners, which can scratch or damage the surface of the cabinet.

Dry the surface: After cleaning, dry the surface of the cabinet thoroughly with a clean, dry cloth. This will prevent water spots or streaks from forming.

Avoid contact with hard objects: Avoid placing hard or sharp objects on the cabinet surface, as they can scratch or dent the metal.

Polish the surface: To keep the cabinet looking shiny and new, polish the surface regularly with a commercial stainless steel cleaner or a homemade solution of olive oil and vinegar. Apply the cleaner with a soft cloth and buff until the surface shines.
