Hydrochloric acid (which is also called muriatic acid in its diluted form), as well as phosphoric acid and sulfuric acid may be used in rust removal formulas using strong acids. These are mineral acids, and they are highly corrosive, especially in concentrated forms.
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.

Yes. First paint both sides of the rusted area with POR-15; then use body filler or putty as soon as the POR-15 is dry to the touch.
Reaction between Vinegar & Rust
Applying vinegar to rust dissolves the oxide and leaves behind a water-soluble salt that you can remove easily. It is called neutralisation, and this reaction happens between rust and acetic acid, which is why cleaning vinegar helps remove iron oxides from household surfaces and objects.
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.
Rust is what happens when iron reacts with the oxygen in air or water. Most rust can be easily removed with a combination of abrasion (tinfoil) and corrosion (phosphoric acid, found in Coke).
Residue – While WD-40 can be effective for cleaning and shining, it may leave a greasy residue if not properly wiped off. This residue can attract dust and dirt, potentially leading to a dirtier surface over time. Potential Damage Over Time – Frequent use of WD-40 on car paint is not recommended.
