Pickling

It’s the basic treatment to remove oxide trails caused by thermic alterations (such as welding). Pickling is not just an aesthetic treatment to remove the “welding dark color”.
Actually, a good pickling action has to remove the chrome depleted surface layer consequently to thermic alterations, sensitive area for corrosive attacks as it’s not protected; it cleans the “welding dark color” only as a secondary effect.

A good pickling treatment takes about from 1 to 2 hours and has to act on a clean and degreased surface, because if there is oil or grease, then the pickling product works only as degreaser and not as pickler. For this reason the degreasing treatment is essential before pickling.

It’s possible to carry out this treatment by spray, immersion or brush.
