Final answer:

Technician A and Technician B are both incorrect. It is not acceptable to use Brake cleaner to clean throttle bodies, and it is not acceptable to mix DOT 5 Brake fluid with DOT 3 Brake fluid.

Step-by-step explanation:

Technician A and Technician B are both incorrect.

Firstly, it is not acceptable to use Brake cleaner to clean throttle bodies. Brake cleaner is specifically formulated to clean brake parts and should not be used on the throttle body, as it can cause damage to the delicate components.

Secondly, it is not acceptable to mix DOT 5 Brake fluid with DOT 3 Brake fluid. DOT 5 brake fluid is silicone-based, while DOT 3 brake fluid is glycol-based. These two types of brake fluid should never be mixed as they have different chemical properties and can cause brake system failure.
