Stainless steel may develop stains from heat, minerals, or cooking oils. These are normal and easy to remove.
- Rainbow or blue marks: wipe with white vinegar or lemon juice, rinse, and dry.
- White spots or chalky residue: simmer a 1:1 mix of water and vinegar, then rinse.
- Brown or burnt stains: use a baking soda paste or a stainless-steel safe cleaner and scrub gently.
- Streaks or cloudy film: rinse with vinegar and dry with a soft cloth.
Avoid steel wool or bleach, use medium heat, and always dry the pan after washing.
