Subject: What are the rust removal products made out of?

Hi,saw your article on rust.Wonder if you could  answer a question?Do 
you know what the new user friendly,environment friendly  products for 
rust removal are made of?I currently dip my antique auto parts in  
phophoric acid and water solution.This removes rust but is not user 
friendly.The  new products have a low ph,no fumes,no acid burns,and 
supply a degree of rust  prevention to the metal surface.Also I've 
heard of adding chromium acetate to  the phosphoric acid for rust 
conversion to a primer.Are you familiar?Regards  Larry
