tools to avoid rusting?
To prevent kitchen tools made from iron from rusting, one can paint them, use stainless steel alloys, or store them in a way that prevents contact with air and water.
To help preserve kitchen tools from rusting, there are few precautions that you can take. The first method is painting iron tools. Water and oxygen come into touch with iron and cause rust, but a coat of paint can stop this from happening. The iron is immune to rust as long as the paint is still on it.
Another strategy is alloying the iron with other metals to form, for example, stainless steel, an iron alloy containing a small amount of chromium. Chromium tends to collect near the surface, where it erodes and forms a passivating oxide layer that protects the iron from rusting.
Lastly, storing your iron kitchen tools under kerosene or mineral oil or in sealed containers could prevent rust by limiting their contact with air and water.
