How could i achieve this look?

Hello Community, I am new to blender, I am working my way through learning texturing and render in eevee.
I am using a still life image on line by the artist Simone Riley as a reference.
I am wandering how i can achieve the dirty glass bottle look and the old aluminium flask. Thanks in advance.
