Rust is a problem for most metal products. Getting rid of it can be tricky. Especially when it comes to cleaning up corrosion in hard to reach places. For example, on the carving of parts and hardware. There are many ways to get rid of a harmful growth, but not all of them are equally good.
Manual cleaning

Manual cleaning of threads from rust is one of the simplest, but not the most effective and fastest ways to resolve the issue. Most importantly, such cleaning does not require "serious" funds. It is enough to have a hard brush and any "aggressive" liquid on the farm. For manual cleaning, gasoline, kerosene, and an auto cleaner are suitable. Just soak the rusted items in the liquid for a couple of hours, and then brush them well. If you can't clean it right away, repeat the simple procedure to the bitter end.
Dry cleaning

Chemical methods of cleaning threads from rust differ from manual ones in much greater efficiency and speed of solving the problem. However, in order to implement such measures, you will have to acquire special means, as well as remember about safety precautions. In addition, dry cleaning differs from manual cleaning in a wide variety of methods.

Soaking the parts in sulfuric acid with an inhibitor or zinc will help remove rust. After such soaking, you still have to work with a brush, but you will have to rub an order of magnitude less than with manual cleaning.

In addition, you can use such "old-fashioned" techniques as soaking in Coca-Cola, in a solution of glycerin, water and tooth powder, in a slurry of soda and water. Potatoes and laundry soap (you need to rub the part with them), as well as fish oil and even "porridge" made from flour and vinegar, copes well with rust.
We finish any cleaning by rinsing off the used composition or solution under running water.
