Then rinse it thoroughly and wipe it with a towel. Brass is a metal that naturally patinas over time and can sometimes leave slight black marks on your accessory. They can be easily removed with a bit of white vinegar. Our accessories are sturdy but not indestructible, regularly check the overall condition of your collar.
