True or False: To remove flux residue, it's recommended to douse the joint with hot water before it has had sufficient time to cool.

The statement is false. It is not advisable to douse a joint with hot water before it has had sufficient time to cool. When solder or braze joints are exposed to hot water immediately after the application, it can lead to thermal shock, potentially damaging the joint or causing it to weaken. Additionally, the intention of removing flux residue is to ensure the integrity and cleanliness of the joint, which is best done after the joint has cooled to avoid issues that could arise from rapid temperature changes.

Proper practices recommend allowing the joint to cool naturally, and then cleaning the residue with an appropriate degreaser or solvent, depending on the type of flux used. This approach ensures that the joint remains solid and maintains its strength, avoiding any unnecessary complications that can arise from improper cooling techniques.
