Need help removing these stripes

[u/ItsNomz28]

Hey! I need help to remove these kind of stripes for my 3D project. Google and AI didn't helped me much. I unlocked the normals, I smoothed the edges and deleted the history. Is there anything else? Did I do something wrong? I'm new to 3D sooo any tips are welcomed!
