To take off a stuck earring back, called a clutch, wash your hands with antibacterial soap and then rub a small amount of petroleum jelly on the back of the earring. After it’s been oiled, hold the front of the earring firmly in place and turn the clutch gently to loosen it.
If turning the clutch doesn’t work, try gently moving it back and forth to get it back on the post. If it’s hard to get a good grip on the clutch, hold the earring firmly and use tweezers to grab the clutch and pull it off the post.
Before you try to take the earring out of a new piercing, use a cotton swab and a sterile solution like hydrogen peroxide to clean the area around the piercing.
