I believe that's the water...

Was it just water or something else also? (e.g. soap)

You can always spray it again if you want to.

You put this plate in the dishwasher with an alkaline capsule, didn't you? I can't imagine how else such amount of the zinc layer could have been etched away. There's not much you can do about it now, except to just replate the affected part or repaint the entire chassis.

Thank you so much,

I simply washed it by hand with water and hand soap. The strange thing is that when I submerge it in water, it looks perfectly fine. The problem appears when it dries. I am attaching photos.

I would be very grateful if anyone has any ideas.

Thanks again!

Polish it with a leather chamois, like you would chrome on a car.

It looks like hard water and alum oxide layer. Mechanical polishing with a low abrasion buffer should shine it right up.

Wow, ignore my first comment, in the first picture it looked like the zinc layer was etched all the way down to the iron, but now it looks like that polishing would be enough here, as wierd_w suggested.

Very important to not use an abrasive.

Soft leather chamois, and nothing else. Zinc is soft and easily damaged/stripped off.

Make sure there are no dirt particles on either the surface or the chamois.
