Rust treatment and removal
(OP)
I have a 5 years old car and I find that some of the parts like door hinges and bolts etc are starting to get rusted.... is there a product available that would clean and protect these parts?

Would there be any benefit to applying these products to clean carbon steel before priming?

They react with rust, not iron.

It is H3PO4 based product and does a marvelous job with the greatest of ease. The H3PO4 products are excellent wash primers for some paints especially oil based, lacquers, and some epoxies. It made by nearly everyone Duro, Permatex, and Loctite to name a few.
The rust converters as mentioned above work mainly with reacting tannic acid or a salt with the iron oxide. They seem to work best with lite rust. I've had very poor luck with thicker rust scales. I've found that if you can knock off the loose stuff, treat it with Naval Jelly and let it age a day or so then apply the converter it work quite well with oil based paints.
Most H3PO4 products are a good wash primer for new steel. They work as stated above with most water based paints being excluded.

If the corrosion you see is on the stamped edge of a hinge or the formed edge of hardware it is most likely "edge" corrosion. Root cause is usually ineffective adhesion of the surface coatings to the comparatively rough edges seen in these parts. It is not an uncommon concern in automotive even in mildly corrosive environments. It is usually cosmetic in its early stages and can be treated using a phosphorous based solution sparingly. Too much for too long may stain. A brush touch up after removing the residue may fix it.
If it is coming from under a bolt on hinge you may find the unibody is not painted at the interface. Use the same process above.
