Place items with their brass hardware in a pillowcase or washing bag and wash on cold with standard detergent. Hang to air dry.
To clean the brass; Squeeze half lemon into a bowl. Add 1 teaspoon baking soda to the bowl to create a paste. Gently rub the paste in one direction on brass. Rinse off and dry. Buff with a clean, dry cloth. Repeat as necessary until brass shines.
