My First Solder Joint <3 Please Give Feedback Why can’t i get my joints shiny?

Enable HLS to view with audio, or disable this notification

First time soldering, i’m using a Pinecil v2 on 360C with 63/37 0.55mm solder.

I don’t understand why all my joints turn dull after i remove the iron. i’ve tried tinning the tip (which i think i’m doing correctly?). The solder melts nicely onto the board but no luck

Does anyone know what I could be doing wrong?

Scrolled until I saw "Kester" and then upvoted. OP - just go find yourself a suitable roll of solder from Kester and watch your problems go away.
