Rust Transfer

Hey guys,

So I purchased a 2015 15" Macbook Pro and I'm a super happy customer for what I got. The only thing that haunted me before with my Macbook Air, was that if I touch any rusty metal, or rust dust or something of the sorts would transfer to my macbooks aluminium finish.

So keeping things short with this, if I touch something that has a bit of rusting showing like a screwdriver or something like that with signs of rust, and after washing my hands can the rust transfer, and affect my macbook ?

Thanks in advance.
