Ok, it seems a silly question, but I want to know if I keep TF toys with rust along with ones without rust, let's say in a plastic bin or in a display cabinet, will the clean toys be "infected"?

Thanks in advance.  

 

I'd say that unless the metal parts were touching other metal parts, you have nothing to worry about. Oh, and get some WD40 and scrub that rust off. Carefully.

 

^This.

Rust is autocatalytic, not contagious.

 

It can be.

 

Most screws that would rust are recessed into the plastic. I don't see why this would be a problem.

 

Thanks for all the replies/advice guys, really appreciate it!  

 

Is it cosmic rust or just regular rust?
