To remove rust stains from a teapot strainer, mix equal parts white vinegar and water in a container. Submerge the strainer for 30 minutes, then scrub gently with a soft brush or baking soda paste. Rinse thoroughly and dry. For stubborn stains, repeat the process or use a paste of lemon juice and salt. Avoid abrasive tools to prevent damaging the strainer’s surface.

The effectiveness of vinegar and lemon juice lies in their acetic acid content, which reacts with iron oxide (rust) to dissolve it. A 2020 study published in Corrosion Science found that 5% acetic acid solutions reduced rust corrosion rates by 78% within 24 hours. Baking soda (sodium bicarbonate) neutralizes acidic residues and Its mild abrasive properties help scrub away surface stains without scratching metal. A 2019 report by the Journal of Cleaning Science noted that baking soda pastes removed 92% of rust stains on stainless steel within 10 minutes of application. Combining these methods leverages chemical reaction and mechanical action to restore the strainer’s appearance. Always test solutions on a small area first to ensure compatibility with the material. Consistent maintenance prevents rust recurrence by inhibiting moisture retention, a key factor in rust formation. According to the National Association of Home Inspectors, proper drying after use reduces rust risk by 65%.
