Remove Concrete Rust Faster

As a neat-freak, I want to see my place organized and best of all, clean. But, nature has it that our stuffs, and house in general, are also deteriorating. I have been only using acid to do away the rust or scrape them off with a metal but then, these only remove the outer layer of the rust. That is quite tedious too. I have to spend the entire one hour only on small area. This is really what I hate in cleaning.

But, would it be better if you can remove rust from concrete using natural ingredients without the usual hard works? We are also a family with all sorts of allergies. For one, my kid is asthmatic. We usually catch colds from harsh scents of chemicals.

However, these ingredients are naturally organic, so we don't have to worry with stingy smell. More importantly, you can also have natural and organic care and cleaning stuffs for your car, pets, carpets and for the entire households. Simply incredible.
