**The answer is phenolics. Tuberculocidal disinfectants, the ones proven to kill TB, typically fall into this class.**

Quats are common and effective for everyday shop sanitation, but they're not the category tested against TB the way phenolics are. Sanitizers and antiseptics are different tiers entirely — sanitizers reduce germs to a safe level, and antiseptics are formulated for skin, not tools.
