Subject: What bactericides could be used in preventing the growth of rust on nails?

I am doing an experiment dealing with the growth of rust on nails and 
whether a strong bactericide could be a factor that prevents this growth. 
So, I have two variable groups: one jar containing a powerful bactericide 
that might prevent the growth of rust on the nails, and one containing 
some natural baceria, such as dirt from the backyard, that would enhance 
the chance of bacteria growth. So basically, I am just looking for some 
examples of some bactericides that might be able to prevent the growth of 
rust on nails. Also, I am not looking for any deadly bactericides that 
could kill anything it comes in contact with, just some strong ones that 
could prevent rust from growing.
