How to quickly remove rusty tin?

Thick rust is mainly composed of iron oxide and a small amount of ferrous oxide. Mechanical methods are not easy to remove, and it is also difficult to remove with vinegar. It should be brushed with 3-5% dilute hydrochloric acid, which is simple, rapid and thorough and has the best effect. Dilute sulfuric acid is also acceptable. And easy to obtain. Idea, acid solution has a strong corrosive effect, so it must be protected. Never let acid get into your eyes! Thank you for your adoption.
