How to Avoid Rust. Metal cookware should not be allowed to air dry to prevent rust from developing. After washing, dry the metal pan with a microfiber towel to eliminate any remaining water from the pan or flatware. Place the towel in the sun to dry it out.
If you don't have time for this step, then at least open a window while drying your pans.
Now, if you want to go the extra mile, then apply a protective coating to your cookware. There are two types of coatings: non-stick and enameled. Non-stick surfaces are easy to clean and don't require special treatment other than occasional oiling. Enameled cookware is coated with a layer of hardened glass mixed with metals such as iron, steel, or copper. These materials provide heat resistance and durability to cooking tools. They also help retain flavor when cooking with fat or salt. Unlike non-stick surfaces which tend to wear away over time, enameled cookware can be used for many years without replacement.
Non-stick surfaces are very convenient because they don't need to be cleaned after use. However, these surfaces cannot withstand high temperatures very well so baking recipes won't come out right unless you use some type of spray oil on them regularly.

How to Remove Rust
The following are the most effective strategies to avoid rust:
Stainless steel is not appropriate or cost-effective for all purposes, but it will suffice in many. Apply Oil: An oil coating will assist to prevent or delay rust because it prevents moisture from accessing the iron in the metal. This method isn't recommended for all stainless steel, just some brands.
Anodize: This process creates a hard, color-changeable layer of oxide on the surface of the metal. It can be done either before or after cooking with no effect on the flavor or nutrition value of the food. This is your safest option for preventing rust if you can afford regular anodizing fees ($30-$100 per panel).
Aluminum/copper/zinc pouches: These are lightweight, inexpensive options that can be used instead of plastic if you plan to cook the noodles right away. They are available in different sizes and can be reused for storing rice or other grains.
Wooden spoons: These will help to protect the blade of your knife as well as the outside of the pan. Make sure to wash them thoroughly after use.
The keys to keeping stainless steel clean and rusted free are oil and heat. Always wash hands after handling steel tools and always rinse vegetables under cold water to remove any lingering salt.
You may paint over rust to stop the deterioration without having to sand all of the rust off the metal's surface.
