We will need:
1. Hydrogen peroxide (3%).
2. Citric acid.
3. Salt.
In order to make it more visual, I specifically do everything in a glass jar.
We produce the rust remedy itself:
1. Pour 100 ml of peroxide into a jar.
2. Pour 30 grams of citric acid.
3. Pour 10 grams of salt.
4. We actively mix and lower
the metal things into the jar.
Now we wait an hour and take sparkling objects from the jar. Attention, this process is best done outdoors!
I hope that my advice will be useful to you. Thank you for your attention!
