How to Remove Aluminum Corrosion on Pans
Aluminum by itself would be too weak and soft to perform as a metal, but as an alloy it's strong and durable. Aluminum cookware is usually cast in a mold with other metals to keep it from bending out of shape and from burning. Aluminum is also very susceptible to oxygen and prolonged exposure will create a gray dull appearance to your pots and pans. This sign of exposure can be cleaned with regular maintenance.
Step 1 – Preparation
Fill the sink with warm water and pour in some mild detergent. Washing liquid is a good option. Use a non abrasive cloth to scrub any excess grease from the outside of the saucepan. It is important that you remove any surface grease before you attempt to clean the corrosion.
Step 2 – Boiling
Pour warm water and cream of tartar into the aluminum saucepan and place it on the heat. Allow the water to boil and simmer for approximately five minutes. Remove the pan from the heat and scrape any excess corrosion or burnt-on food from the inside of the aluminum saucepan. If this procedure partially cleans the inside of the pan, repeat the process, with fresh water and scrape until the aluminum pan is free of corrosion on the inside.
Step 3 – Abrasive
Clean the outside of the aluminum saucepan with an abrasive cleaner. Use circular movements to clean the saucepan and bring back the shine. Clean the bottom of the saucepan with the same method and bring the shine to that part also.
Step 4 – Inside
Once the inside has been boiled and freed of excess grease, food or corrosion, you may still find an element of dark gray staining. To remove this, pour in some white vinegar and bring to the boil again. Pour the hot vinegar away and scrub the inside of the saucepan with an abrasive cleaning pad. Repeat the use of circular movements and remember to get into the edges of the saucepan to remove the entire gray coloring from the inside of the saucepan.
Step 5 – Polishing
Once the saucepan has been cleaned and the corrosion has been eliminated, dry the saucepan with a clean, lint-free dish towel. Take some kitchen paper and pour some of the olive oil onto it. Wipe the inside of the saucepan with the olive oil and coat the entire inside of the saucepan. Wipe the outside of the saucepan with any leftover oil from the kitchen paper. Use a fresh piece of kitchen paper to wipe excess oil from the outside, just leaving it clean and shiny. Wipe the rest away with the clean dish towel.
