Need help removing a color from a reflection

I’m working on isolating some photos in PhotoShop, and this one I’m working on is giving me some trouble. There’s a corner of the image (see photo) that is reflecting some yellow paper that was sitting nearby when the picture was taken. I’m trying to remove that yellowness, and make it consistent stainless steel like the rest of it is. Can anyone give me any ideas on how to go about it? I’ve started messing with the Clone Stamp and Pattern Stamp tools, but it wasn’t quite working how I’d hoped. Thanks!
