Use a brush or a sponge to apply the product onto the part to be pickled. It can also be diluted in water for use by immersion or in suitable washing machines.
Dilution varies from case to case and in a very remarkable way: 1/1, 1/3, 1/10 up to 1/50 and more. In these cases, the particles of iron or foreign metals present on the surface are also eliminated (passivating cleaning of steel).
Always check dilution and immersion times.
