All sterling silver jewelry will tarnish, becoming dull and turning dark brown or black. Sometimes, this happens very quickly depending on your individual body chemistry, your location, and how the jewelry is stored when not in use. Sterling silver nose studs need to be periodically taken out and cleaned - they are not intended to be worn 24/7 without cleaning. You should never wear silver in an unhealed piercing.
• Keeping your stud looking nice is much easier than cleaning it after it darkens! Use a soft toothbrush and some soap to clean your nose stud after each wear before you put it away.
• If you shower or wash your face with your stud in, always remember to completely dry it after. I don't recommend doing this, though! Dropping the nose stud down a sink or shower drain is one of the most common ways that people lose their nose jewelry.
• Store your jewelry in an airtight bag with an anti-tarnish tab when not in use. The anti-tarnish tabs that I include in my packaging are good for approximately 6 months and will start to change color when they need to be replaced.
If you silver has already darkened, below are three methods you can use to clean your silver nose stud so that it looks just as shiny as the day you got it:
You can buy a small jar of liquid cleaning solution for silver jewelry online and in most department or drug stores. This method will work well for all nose stud bends (screw, L-bend, and bone). Make sure you are using a product that is intended for sterling silver - not gold or fashion jewelry.
I prefer using Herman's Silver Polish over a liquid dip because it's non-toxic and it cleans my jewelry gently. You can purchase it online, and the jar goes a long way when you're only using it for tiny nose studs! A silver cleaning paste will work well for all nose studs bends (screw, L-bend, and bone).
Your package includes a small polishing pad to get you started! Once the entire pad has turned black, you can buy yourself a full sized polishing cloth intended for sterling silver. This method is ideal for cleaning tarnish off of the charm and from around the stones. However, it is not the easiest way to clean a nose screw. You can use it for cleaning an L-bend or a nose bone.
