What to Look For
Dishwasher detergent is harsh. Modern dish soap is fine on cast iron (it's pH-neutral). Dishwasher detergent is the opposite — alkaline, harsh, and designed to dissolve grease. That's the same chemistry that dissolves seasoning.
Soaking is the real killer. Even setting aside the detergent, the 60-90 minute wet cycle is fatal. Cast iron rusts within an hour of sitting in standing water. Hand-washing takes 60 seconds; dishwasher would require 6+ hours of re-seasoning to recover from.
