After completing the brazing process, how should the joint be cleaned?

Cleaning the joint after brazing is essential for ensuring the integrity and appearance of the connection. Using a wet cloth is advantageous because it helps remove flux residues and oxidation that can be left on the joint surface after the brazing process. These residues can compromise the strength and corrosion resistance of the joint if not properly cleaned. A wet cloth allows for effective removal of contaminants without risking damage to the joint itself.

In contrast, using a dry cloth may not adequately remove all residues, while a wire brush could potentially scratch or damage the surface of the joint, leading to defects. Chemical solvents, while effective in some cases, can introduce additional complications such as residue from the solvent or reactions with the metal. Thus, a wet cloth is the most effective and safest method in this context.
