Expert Answer
Following are the methods of prevention from rusting:
i.Putting paint over the surface of iron implements.
ii.Galvanization: In the method of galvanization, surface of iron is covered with layer of more active metal like zinc. In this way, iron is prevented to come in contact of air and moisture which are required for rusting and zinc metal does not undergo rusting and hence, prevents the rusting of iron.
iii.Putting oil or grease over the surface of iron objects.
