Iron does not rust from oxygen itself. Iron needs to be in contact with H2O, which is water and oxygen. So just keep iron out of contact with water, or when you do, make sure you wipe the iron dry. :) Hope this helps!
is a method of rust prevention. The iron or steel object is coated in a thin layer of zinc. This stops oxygen and water reaching the metal underneath - but the zinc also acts as a sacrificial metal .
