How To Care For Your Brass

The Urban Key is made of 100% brass. While brass is antimicrobial, we recommend cleaning your brass key regularly for increased safety.

Options for at-home brass cleaners:

Lemon Juice And Baking Soda

Combine 1/2 a lemon with 1tsp of baking soda. Apply with a soft cloth. If the wear is extensive, let the paste sit on the brass for 15-30 minutes. Rinse with warm water and dry.

Lemon Juice And Salt

Rub 1tsp of salt on 1/2 a lemon. Rub the salted lemon on your brass until clean. Rinse with warm water and dry.


Yes, that's right, ketchup. Cover your brass with ketchup and let sit for one hour. Rinse with warm water and dish soap and dry.
