You can soak a soft cloth in vinegar and tie it tightly around kitchen and bathroom taps to remove stains. You must ensure the cloth stays wet and does not dry out. You can pour vinegar into a small plastic bag, submerge the tap nozzle in it, and tie it with a rubber band if only the nozzle has stains. You should remove the cloth after 15 to 30 minutes and scrub the area with an old toothbrush. You can wash it with clean water and wipe it with a microfiber cloth to make the tap shine like new.
Keep this in mind
You must never mix vinegar with bleach or chlorine-based cleaners. This mixture releases dangerous gases. You should wear gloves and keep the room well-ventilated while cleaning.
You must test vinegar on a small patch before using it on marble, natural stone, and certain metal surfaces. You can develop a habit of wiping taps with a dry cloth after use to prevent new stains.
