Using a metal-bristled brush to clean tungsten carbide jaws of needle holders is correct because tungsten carbide is a very hard material that can withstand the abrasive action of metal bristles. This type of brush effectively removes debris, blood, and tissue from the intricacies of the jaws without damaging their surface or compromising their functionality. The hardness of tungsten carbide means that it can endure the scrubbing action typically associated with metal brushes, making them suitable for maintaining the precision instruments used in sterile processing.

Other types of cleaning tools would not be as effective; for example, soft bristle brushes may not provide the necessary abrasion needed to clean effectively, while disposable sponges might not have the scrubbing capability required for tougher residues. Identity-marked brushes are often used for specific tasks and to prevent cross-contamination, but they do not directly pertain to the cleaning of tungsten carbide jaws in this context.
