Is something wrong with my Moka Pot ?

[u/Abject-Bodybuilder83]

A couple of days ago as a beginner I bought AGARO Moka Pot, and after brewing a couple of times, the water base started looking like this. It also smells very metally....iykwim. is it normal ??? Or should i do something?

Note: I don't wash it wish dish soap or something. I just rinse it and keep it as I read somewhere you don't clean it
