Can you remove tarnish on this aluminum kitchen tool?

Take a green Scotchbrite scrubby pad to it. The tarnish is only a few molecules deep, and the green scrubbies are abrasive enough to remove that layer. It will also remove that nice, shiny finish, however

The shiny finish is already long gone. No worries there. The only other concern is that the face with the sharp points all over it might be impossible to get in between. Is there anything I can also soak this hammer in?

For the toothed face, wet an old toothbrush and pack some baking soda into the bristles. That’ll do it.

I would try immersing it in good old Coca-Cola. Seriously.

That might actually work and it’s a better use of the Coke than drinking it

The Coca-Cola trick seemed like it might work when I started, but this turned into a huge mess. When it comes down to it, I can’t see myself using this tool for food prep. It’s tarnished to the point that it turns anything it touches black. :(
