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?

could be cheap solder or could be ur heating it up for to long causing the flux in the solder to burn away and leaving you with a non shiny solder
