Some helpful tips I have learned over the years in collecting silver:
SAVE those little silica packets you get in shoe boxes, etc. They absorb moisture. Stick them in your china cabinet, drawers, silver chests, or places you store your silver. It really helps slow down the tarnishing! They are great for items that are bagged as well!
DO NOT let your silver air dry but dry it immediately.
DO NOT USE toothbrushes or scrubbies to clean! Use a soft cloth, foam sponge or soft horsehair brush. Also, leaving the color in the crevasses helps add depth!
