Lasting legacy from my mother-- the dish scrubber she gave me a few years ago that I just used-- "it's wonderful, gets absolutely everything off but it's soooo gentle!" has wrecked the inside enamel of my Le Creuset.

That thing I will probably never be able to buy more than once in my life, that thing I saved up forever for, that thing that totally changed my cooking game. Sure I bought it 50% off at a discount store, but it's still more than I could ever dream about spending again.

For good measure-- I was using both my Le Creuset and my cheaper Sur La Table knockoff and washed them at the same time, so now that's wrecked too.
