To remove stains from a kitchen sink faucet, mix a solution of equal parts white vinegar and water. Soak a cloth in the solution and wrap it around the stained area of the faucet. Let it sit for 10-15 minutes, then scrub gently with a soft brush or sponge. Rinse thoroughly with water and dry with a clean cloth. This method effectively removes mineral deposits and stains without damaging the faucet's finish.

Removing stains from a faucet restores its shine and prevents buildup that can affect performance. The vinegar solution is gentle yet effective, making it a convenient option for maintaining your kitchen faucet’s appearance and functionality.
