Help with discoloration question please

[KelchUSMC]

This is my AR-15 that I picked up several years ago. It had faint discoloration or smudgy white whatever around the text. Never really bugged me until I got it out recently and I'm curious if there is something I can do to clean it up.

Not entirely sure what previous owner has used to clean it up. I only use regular gun lube (CLP or whatever) and soft rags.

Looks like a sloppy DIY color fill job by the previous owner. You might try hitting it with some acetone, but you may also lose the color fill.

Hrmmm, maybe I'll try that then. Just wanna clean it up a bit, but I guess it doesn't really matter. Won't damage the actual receiver will it?

Why would it, the receiver is metal and that is just paint. Paint is used to preserve what is underneath.

Acetone definitely won't hurt the original black anodized surface.

I have no idea, that's why I'm posting. If I knew anything about it I wouldn't have posted.

Alright, awesome... I'll see if that works then. Thanks again.
