Quick Rust Removal
Here is an incredibly fast and inexpensive way to remove rust without using abrasive materials, hot tanks, or specialized rust removers:

Muriatic Acid (aka Hydrochloric Acid) is quite inexpensive:

It can also be found at local hardware stores:

(It isn't "standard" muriatic acid, so it may not be as effective as the Acid in the video)
Acids react quite well with most metals, any HCl residue left on clean metal will continue to react. So it is necessary to rinse the clean metal with a strong Chemical base to neutralize the acid, like vinegar, lye, or baking soda dissolved in water.
It may be desirable to dilute the Hydrochloric Acid with water before using it to remove rust. This would create less fumes, it would be safer for the person using the acid (just in case it comes in contact with clothing or skin), and it would give the person time to neutralize the acid, just in case it begins to react with and corrode components that the person wishes to keep intact. A slower reaction time is preferable.
It may be useful to have two tanks, one filled with a water solution of HCl and another tank filled with a water solution of a strong base like lye or vinegar. Place the object one wishes to clean in the HCl for a couple of minutes, check on the object to ensure it isn't reacting with the clean metal, and once it is sufficiently clean, place the object in the lye or vinegar.
Here is the ideal way of using HCl to remove rust:

This method holds several advantages over electrolysis:
1. It is faster. A couple of minutes vs a couple of hours
2. It can clean the coolant passageways in cast iron engine blocks, unlike traditional electrolysis.
3. This method may also remove burnt caked oil, carbon deposits, and possibly gasket material that bonded with the block.
Be careful, HCl also reacts with the human body.
