Hey, attached are the battery terminals of a unit I’m cleaning up. Any advice on cleaning these corroded terminals? I would like the unit to be able to function with batteries. Thank you in advance.

You can get light rust / corrosion off with with sandpaper. Some use a paste made from water and baking soda to clean. I've also seen lemon juice used to clean corrosion. I would start with the baking soda paste and then go from there. Your terminals do not appear to be too bad.
I did the baking soda paste and it worked very good. Much thanks!

I haven’t seen too many people mention it, but magic eraser would prob work well too.
I used a dish scrubby once to clean a chrome piece and with some elbow grease it took all the corrosion off. Took a while but doesn’t leave behind any scratches. The kind that are sponge on one side and sand paper on the other but soft.

Baking soda and water paste has been a trick for battery corrosion in the auto world for decades. Very cheap solution that's already available in most households.
It's excellent on the green corrosion but will also attack rust. I've used it many times on rusty terminals.

If you can pop the coils out, soak them in vinegar. Take a toothbrush to it occasionally to kick off loose chunks.
Depending on the amount of rust it will be 100% clean after about 2 to 5 days
