I've been putting my LC Dutch ovens in the dishwasher for 20 years without problem.
LC website says they are dishwasher safe but that the finish might dull some over time with constant dishwashing.
I washed one of mine in the dishwasher the other day and I opened the dishwasher door to a trashed exterior finish. It's dull and looks like it's coated with dust and you can mark it by running your finger over it?
What happened? I used the same detergent as always and no other unusual items were washed with it.
Is it safe to use?
