The oxidation mechanism involves the introduction of oxygen molecules into the surface structure of the metal. Each metal reacts to this in its own way: it darkens, becomes covered with rust or patina.
How to clean metal before painting
Professionals use a 5% aqueous solution of hydrochloric or sulfuric acid with an inhibitor (it slows down oxidation, prevents damage to the metal), or a mixture of vaseline oil and lactic acid - they turn corrosion into iron lactate and dissolve it. At home, vinegar, soda, citric acid are suitable.
How to clean metal from corrosion at home
Prepare a mixture of salt and soda, add a little water to make a homogeneous thick slurry. Apply the mixture to the rusty areas, soak for 30 minutes, then rub with aluminum foil or a brush. After such cleaning, the integrity of the surface structure of the metal is violated, so protective agents must be applied.
How to wash dirt from metal
Vinegar and lemon juice
The simplest rust remover is a mixture of vinegar and lemon juice. We mix them in equal proportions and apply to the rusty surface with a sponge or cotton swab (while avoiding contact with mucous and wound surfaces).
