For stubborn rust, citric acid may be the way to go. Make a paste using two parts baking soda and one part lemon juice, and then apply the paste to the rusty area using a sponge and allow to sit for at least 30 minutes. Use a brush or steel wool to scrub away the rust from the metal.
To tackle items with significant corrosion, submerge your rusty tools or knives in a bowl of white vinegar and let them sit overnight or as long as 24 hours. Once they have had a good soak, remove them from the vinegar and scrub the rust off with steel wool, a scouring pad, or a wire brush.
All you need to do is sand away the areas affected by rust (you may need to use a wire brush if the rust has begun to cause scaling), apply a protective coating like oil or dry coat, and then seal the area in with a rust-preventing paint or clear coat.
Tools that are too large to fit in a container can be wrapped in a cloth soaked with vinegar and sprinkled with salt, then put in a plastic bag. The vinegar-and-salt mixture needs time to break down the rust. This can take anywhere from one to three days. Check the tool periodically to see if the rust has softened.
Vinegar and Baking Powder:
Baking powder can work wonders with rust. It makes an effective paste mixed with vinegar. Rub the paste onto the rust spots and leave to work for at least 30 minutes. Rinse off with warm water.
However, please don't leave it on any surface for too long, as vinegar can erode it, weakening the metal and making it more susceptible to rusting.

The most common way to stop rust on metals is by fragmenting or brushing the metal surface using sandpaper. Another rust removal method is to apply phosphoric acid which converts the red iron oxide into black ferric phosphate on direct application to rusted iron.
Everyone from the professional to the DIY home handyperson has come across rusty tools. Tools can become so rusty that they seem entirely unusable. But before you throw them away, know that you can make them work (and look) like new by applying a little CLR Calcium, Limescale & Rust Remover.
You simply spray it on the surface, wait around ten minutes, and scrub it off with something abrasive. Its lubricating qualities loosen the bonds between the rust and the metal surface it has adhered to. And because it's also a moisture deterrent, it offers temporary rust protection after its initial use.
With so many choices, it's not easy, but we have a clear favourite. Our top pick is the JENOLITE Rust Converter Spray, thanks to its fast-acting formula, easy application, and long-lasting protection. It neutralises rust in 15 minutes, creating a paintable surface that prevents future corrosion.
A common method of dealing with rusted screws and bolts implies removing them from their sockets and leaving them to soak in a hydrogen peroxide solution overnight. Hydrogen peroxide is known to dissolve accumulated rust from metal surfaces and can even break up the entire tarnish in some cases.
Coca‑Cola can help clean rust or corrosion, because it contains phosphoric acid, an edible food acid found in lots of foods and drinks. Any acidic drink like orange juice, lemon juice and champagne has the same effect as Coca‑Cola on metal.
To remove light rust, leave parts in the solution for 1-3 hours. To remove heavy rust, leave parts in the rust removal solution overnight. Do not use on parts that have bluing, browning or protective oxide paints, as those protective coatings would be removed.

Dawn dish soap can help clean metal surfaces but is not specifically designed to remove rust. You'll need a more potent agent like vinegar or a commercial rust remover for rust removal.
As you can see Coke didn't do much to remove rust. Being less acidic than the other 2 liquids it would probably take more than 24 hours for it to be effective. Vinegar on the other hand does a good job (6% acidity, PH between 2.5 and 3) but leaves some rust attached.
While vinegar by itself is a mild acid, the salt increases the acidity in the solution and let it chew rust even faster. When using a full gallon of vinegar, add a full cup of salt per gallon of vinegar. For this block plane, two hefty tablespoons, distributed evenly, was the perfect amount.
