Hello DOMD
Welcome to the Coffee Forum web site!
I've never looked inside of a Bialetti Moka pot.
Is the inside of your Bialetti made of real metal or the silver-shiny fake looking metal that's sometimes used for things.
Will the metal particles stick to a magnet?
You'd be surprised how many new things have metal particle residue in them. I'm surprised when I see people taking things out of the box and using them without washing them first. I've seen the metal shavings on cookware and bakeware dozens of times, so it really doesn't surprise me that there would be some in your Moka Pot. What surprises me is that there is so much. Quality control at the factory should have spotted that!
If you wash it thoroughly a few times and wipe the parts with a new paper towel each time, as well as run a few brews through the Moka pot, the metal particles should be gone.
Of course, contacting the manufacturer may result in you getting a new replacement Moka pot. It's worth a phone call.
Good luck with your new Moka Pot. Please let us know how everything works out.
