While you want to clean connections, little is gained polishing the antenna overall as it actually increases its deterioration. As aluminum weathers it forms a oxide layer than slows further oxidation. Removing this oxide looses a few thousandths of aluminum and open door to further accelerated loose vs what you would see without polishing. Also while it might not be case here sometimes aluminum is coated with a very thin layer of pure aluminum (called Al Clad) that is very resistant to weathering, polishing will remove it.
I think we specifically mean to clean the pipe joints with steel wool. Not the whole antenna. I would never remove oxide as it actually protects the antenna. Only remove it at the connecting joints.
I agree but LXP's post seems to suggest polishing whole antenna then waxing it.
