I doubt it. First of all Burton's no newbie, and I'm sure he can recognize SS spokes vs. plated. But more important, carbon and alloy steels would have rusted in the classical way, vs the type of brittle inclusions you see in chloride attacks on stainless. This is a unique phenomenon and doesn't happen to most non stainless alloys..

I first hear of in a different context when I dealt in ultrasonic cleaners. When dentists started cleaning their instruments in Clorox using ultrasonic cleaners, suddenly there was a rash of Stainless steel basins turning porous. My ultrasonic vendor sent out letters warning of the problem, and specifying that use of any products containing chlorine directly in the unit would void the warranty.
