To keep your bracelet in the mint condition, make sure you take it off before you take a bath or a shower. Long term exposure to various hygiene products can have a damaging effect on your bracelet.
If you wash your hands, be careful with the soap because it can react chemically to silver. The silver parts should be cleaned from time to time with a silver cleaning cloth.
Also, like with any other jewelry, it is not recommended to wear it when you go on vacation, especially during summer activities on the beach or if you are active with the winter sports.
