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. Once the rust has softened, use a metal brush or steel wool to scrub off the surface.
Allow the object to soak in the vinegar for at least 30 minutes. Check the progress. Excessive amounts of rust will require longer soaking, up to two hours.
Yes, vinegar can react with certain metals and cause them to turn black. This is often due to the formation of metal oxides or other compounds on the metal's surface.
Place the rusty objects inside the container and let it remain for 12 hours or overnight. If the item is extremely oxidised, leave it for a day or two, as per requirement. Afterwards, take it out and scrub with a steel wool pad or a brass-bristled brush to remove the loosened rust.
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.

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.
This is often due to the formation of metal oxides or other compounds on the metal's surface. The reaction is more noticeable with metals like iron or steel, where the vinegar can accelerate the formation of iron oxide (rust), giving the metal a black appearance.
The only real side effect from leaving vinegar to its own devices is that its acidity will gradually decrease over time, making it less potent. This is why a "best by" date can be found on the bottle, but it's still perfectly fine long past that — it isn't an "expiration date," by any means. Vinegar does not expire.
Vinegar. If your tools are significantly rusty, and you are able to submerge them without affecting any of the other surfaces, a vinegar bath can be a good way to remove the rust. Submerge your rusty implement in white vinegar and leave overnight.

Weak acids: Weak acids, like oxalic acid or EDTA react with rust less intensely than strong acids, with a slightly different reaction. These weak acids are less caustic and are safer to work with and they are easy to dispose of.
Leaving a baking soda and vinegar mixture on stainless steel for about 5-10 minutes is usually enough. This allows the mixture to work on stains without causing damage to the surface.

"While white vinegar typically contains around 5 to 7 percent acetic acid, cleaning vinegar might have an elevated concentration, sometimes reaching 6 to 8 percent." The higher acidity level makes cleaning vinegar a great choice for cutting through grease and grime but makes it unusable for cooking.
Acid concentrations: Apple cider vinegar contains about five to six percent acetic acid, while white vinegar contains five to ten percent. This higher acid concentration makes most white vinegars more acidic than their apple-based counterpart.
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.
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.
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.
