Alicia Bodine

Mailboxes take their share of abuse and need to be cleaned every so often to be kept looking their best. Some mailboxes are made out of copper because of the copper's ability to resist wear and tear and remain strong. If the cooper mailbox needs a cleaning, you can't just clean it any old way. There are some great home remedies that will do the trick and restore your mailbox to looking like new.

  1. Slice a lemon into six wedges with your knife. Take some salt and lay it on a flat dish. Now dip the sides of the lemon wedge in the salt. Rub it on the spots of your mailbox where you see tarnish.

  2. Sprinkle some salt into a cup of vinegar. When you see that the salt has disappeared, begin to slowly add some flour. You want your mixture to look like toothpaste. Once it gets that consistency, apply it to the copper mailbox. Let it sit for half an hour and then rinse off with a bucket of warm water. Use a towel to dry.

  3. Spoon out some cream of tartar sauce and add some lemon juice. It can be a little bit runny. Spread this mixture over the mailbox and let it sit for about 10 minutes. Get a bucket of warm water and pour it over the mailbox. Dry with a towel.

  4. Sprinkle some baking soda in a bowl and add lemon juice. When it becomes like a paste, add it to the copper mailbox. Let it sit for 5 to 10 minutes and then wash off with a bucket of water. Make sure you towel dry so you don't leave any water marks.

  5. Squeeze some lemon juice into a bowl and dissolve a tablespoon of salt. Spread over the copper mailbox and leave for 10 to 15 minutes. Remove by rinsing with warm water. Towel the mailbox dry and return it to its post.
