Nonferrous materials like titanium, magnesium, and aluminum form a hard-oxidized layer when subjected to an electrolytic process. Aluminum is the most commonly used anodized material. Because aluminum is cheaper, more sustainable, and a better heat conductor than other nonferrous materials.
Aluminum immersed in a chemical bath – typically made from sulphuric acid or chromic acid, when subjected to direct current forms an oxide layer (Amorphous aluminum oxide). The oxide layer hardens, and as a result, gives the aluminum material a corrosion-resistant property.
Immersing aluminum inside a chemical solution with higher temperature and electrical input improves its corrosion-resistant property because higher voltage and temperature increases the thickness of the oxide layer.
Cookware created from this type of aluminum is known as Hard Anodized Cookware.
Restoring Hard Anodized Cookware
Hard anodized cookware is semi-nonstick and corrosion-resistant.
The hard anodized cookware’s semi-nonstick property saves it from superficial food stains. But over time, hard-to-remove grease stains can build-up to ruin its glossy, stainless body.
The Hard anodized cookware’s corrosion-resistant body is extremely delicate. So using barbaric-methods to restore its previous look will result in a scratch-filled surface. You have to either use a company-made cleaning solution or follow our cleaning method to restore your hard anodized cookware.
How to restore hard anodized cookware?
There are two ways to restore hard anodized cookware, one for removing light grease stains and the other for heavy grease stains.
Follow these steps to restore hard anodized cookware that has light grease stains:
- If you don’t have a company-made cleaning solution, you’ll need to buy a liquid dishwasher and steel wool.
- Take your hard anodized cookware and heat its grease-stained surface on a stove-top. Heat the anodized cookware on high-heat for at least 10 minutes.
- Take a steel spatula and gently scrape the grease stains that are on your hard anodized cookware.
- Pour liquid dishwasher on your anodized cookware’s grease-stained surface. Use the steel wool to scrub the grease-stained surface for at least 10 to 15 minutes.
- If you’ve done everything properly, washing the liquid soap will reveal stain-free cookware.
Follow these steps to restore hard anodized cookware that has heavy grease stains:
- If you don’t have a company-made cleaning solution, you’ll need to buy white vinegar, lemon, baking soda, detergent powder, steel wool, Scotch-Brite, and sandpaper.
- Fill a pot, larger than your anodized cookware, with boiling water.
- Add four teaspoons of baking soda, two teaspoons of detergent powder, two teaspoons of liquid dish wash, a teaspoon of white vinegar, and the juice of one lime to 3 liters of boiling water. Let the cleaning mixture boil for 10 to 15 minutes.
- Place your grease-stained hard anodized cookware inside the cleaning mixture. Turn the heat off, keep the grease-stained hard anodized cookware inside the cleaning mixture until it cools down to room temperature.
- Take the grease-stained cookware out of the cleaning mixture. Use a small amount of cleaning mixture and start scrubbing the grease-stained surface using steel wool.
- Use sandpaper with a little bit of cleaning mixture to remove the remaining hard-stains from your anodized cookware. Wash your hard anodized cookware to reveal a clean, stain-free body.
