Only been using cheap chains, and had a couple in the past that rusted after I washed the bike. But then the wax on them were old. So I suspected it was time to re-wax. The cleaning method (petrol + degreaser + method) will strip the chain of any additives that are originally coated in the factory. So if the outer surface of the chain is no longer waxed, it'll rust after exposed to water.
