I have my late grandpa’s silver spoon attached to my fridge with a neodymium magnet. What kind of chemical reaction causes that discolouration?

I’d use a pencil eraser to polish off surface level tarnish, no need to bust out the grinders here. But otherwise your comment is on point.
He’s not saying use a grinder. He’s describing polishing as micro-grinding.
