Method 4

But this is not all, since cast iron has a porous structure, and acid treatment can be used to remove rust from an especially old-fashioned origin. You have the right to choose between oxalic, acetic or orthophosphorous.

Important! Experts recommend to stop their choice on orthophosphoric acid, as it is more effective. This chemical compound is used for anticorrosion treatment of metal, and creates a protective layer against corrosion.

If someone is embarrassed by the use of acid, then you have another way - to take advantage of the world-famous drinks "Pepsi" and "Coca-Cola."In the allowed amount they contain the food additive E338 - the orthophosphoric acid we need.

Let's consider the simplest method - the full immersion method with the required volume of acid. To do this, proceed as follows:

1. Degrease the frying pan by any means.
2. Prepare a container with a solution in a ratio of 100-150 g of 85% acid per 1 liter of water.
3. Lower the cooking utensils in a container and leave for 1-1.5 hours.
4. Stir the solution from time to time.
5. Remove and rinse with warm water.
6. In the end, make a neutralizing solution in the following proportions: 48% alcohol, 50% water, 2% ammonia.
7. Rinse the frying pan with this solution.
8. Rinse again with warm water and dry.

Important! Do not miss one of the stages, they are all interconnected.

After you safely remove the rust and wash away all acid residues from the cast iron, you must turn on the oven to maximum. Proceed to the procedure for its hardening.
