The powder coat is the enamel. It's a ceramic powder that's sprayed on and then cooked in a furnace.
You have etched it. That, I am sorry to say, is permanent. If you have access to a furnace you could try refiring it, a few minutes at 1500 f would do it, if it can be done at all. You've basically turned a smooth glass layer in to a kind of sponge. You need to melt that outer surface again.
Oh no.
Thanks for letting me know. I may have access to that kind of furnace, but I’m not sure I could convince them to put my stupid little colander in there, because that’s silly.
I appreciate your insight, even though it makes me sad. I kinda thought that might be the case, though. Cheers.
You might also try googling local powder coat seevices, but it may end up being more expensive than just replacing it.
The powder itself looks cheap enough though:

The problem is finding someone with the skill and tools to apply it and bake it. :(
When I needed to anodise an aluminium object, I took it to the back door of a medium-sized coating company that serves businesses. I included a note with some relevant information: "no rush, do it when it's easy for you", acceptable range of colours, and my contact info. Took a while, the result was perfect, the price was low.
