CARE & LONGEVITY
A little thoughtful care will help your jewellery look its best for longer.
Surgical steel is durable and easy to care for. Keep your jewellery clean and dry thoroughly after exposure to water or sweat.
Surgical steel is suitable for regular wear in healed piercings. Keep the jewellery clean and check that any removable ends remain secure.
After contact with sweat, seawater or chlorinated water, rinse your jewellery with clean water and dry it thoroughly using a soft cloth.
Clean gently using warm water and a mild, fragrance-free soap. Rinse thoroughly and dry with a soft cloth before wearing or storing.
Avoid bleach, alcohol, abrasive cleaners and other harsh chemicals.
Store your jewellery somewhere clean and dry, ideally separately from other pieces to prevent scratches or tangling. The pouch provided with your order is perfect for keeping it protected.
Jewellery care is different from piercing aftercare. If your piercing is new, irritated or still healing, speak to a professional piercer before changing your jewellery.
