When I picked up this Kitchenaid 3.5 qt Dutch Oven it had this cast on the finish. None of my LeCruset or other Enameled cast iron had every developed this.   When I researched it, I didn’t find anything that addressed this singular issue.

I do think it was caused by repeatedly putting it in the dishwasher.  But I had wrongly assumed it was lime scale, but it didn’t respond to anything that would remove it on a chemical level.  My conclusion is that the outer finish gets eaten away by the minerals in the tap water.

Experimenting with abrasives to repolish the finish, yielded much better results. Melamine sponges and soft scrub didn’t affect it at all. Metal polish like Simichrome worked a little bit better when applied with a rag. But when I combined it with a scrubbing pad or sanding sponge, it worked a treat!

After a very long polishing session, applying tiny smidgens of Simichrome to small sections at at time and working my way around the pot. I eventually managed to wear the white cast off and get down to a dull colored patina.
