Things You'll Need:
- Salt
- Vinegar
- Flour
- Warm water
- Drying towel
-
Step 1
Combine a mixture of 1 tsp. salt, 1 cup vinegar and flour (as much as needed to form a paste).
-
Step 2
Apply the paste liberally to the copper items you're cleaning.
-
Step 3
Allow the paste to sit for a while for maximum effect--no less than 15 minutes. For items that have been neglected for years or have high levels of corrosion, a longer period of time is recommended (up to 1 hour).
-
Step 4
Rinse away a small area of the paste to test its effectiveness. Determine whether a longer period of time is needed: If the copper below is bright and shiny, rinse the entire item with warm water; if not, allow the paste to sit longer to complete the cleaning process.
-
Step 5
Dry each copper item thoroughly to maximize the time between necessary cleanings. The end result should be a nice, clean, corrosion-free, copper shine.
