How can I get this corrosion off of my turntable platter?

I got a new turntable a couple of weeks ago and I’ve been loving it! I’ve done some maintenance on it (lubrication, cleaning, etc.) however, it appears that there is some corrosion on the aluminum platter and I was wondering how I could get it off? It’s not anything major but it still annoys me whenever I see it lol

2000 grit sandpaper and wet sand it.

I did this with my TD-160 Super that had severe corrosion. Worked for me and my platter looks better than it would have new.
I would use this as a last resort and try aluminum polish first like others are suggesting. I used Brasso after sanding and it worked well for me.

scotch bright and lemon juice

Which product? I see sponges, steel wool, and brushes sold by scotch bright. i also already tried using lemon juice (with a towel) and it didn't work

Maybe the 7448. I’ve used the 7447 before and I worry that it’d be too abrasive. I’d try it on an inconspicuous area first, to be sure. I need to do the same to my platter and was considering the scotchbrite pads. If you do this while on your turntable (which I don’t recommend), I’d remove your head shell and set it somewhere safe as this could cause some fine metal particles that you don’t want near your stylus.

Just be patient, take your time and it'll be good as new
I used to work in corrosion. Please do this and don’t start attacking it with acids and steel wool like others have suggested.
Yeah I was slightly apprehensive about doing what the other people were saying lol. I like doing things the proper way, not the cheap way. Not to mention that doing something super abrasive/acidic sounds like a great way to get more wow/flutter
It’s certainly a way to set the stage for future pitting corrosion issues that cannot be polished out or repaired.
thanks!
Just wondering, do I use it on a specific spot, or would I use it on the entire platter so one part doesn’t look shinier than the other parts?
Start with the discolored spot and see if they match. I'd guess the entire rim will need a bit of polishing to look like new. My Ariston deck needed the full treatment on the platter to shine. It's not hard work but you do need to be patient, take your time.
You'll have plenty, may as well shine up the whole thing.
I need this as well. Thank you and thank op too for bringing up this topic. I have 000 Steel wool and it actually could put a nice shine on it (used it to clean up my frets on my guitar and worked amazingly well), but I want.. a more consistent shine on mine
