Once a leak is discovered, the leak site should be ______ and prepared for brazing or soldering.

Preparing the leak site by cleaning is essential because brazing and soldering require a clean metal surface for the filler metal to wet and bond properly. Oil, grease, dirt, oxide films, and corrosion create barriers that prevent the filler metal from flowing into the joint and forming a tight seal. Cleaning removes these contaminants, exposing fresh metal so the braze or solder can adhere, wet the surfaces, and create a robust, leak-tight joint. Sealing alone wouldn’t remove the contaminants or enable proper metallurgical bonding, and cooling or heating without cleaning won’t preparation the surface for a reliable repair.
