PSA: Old terminal block cleaning trick still works like a charm

Had a corroded terminal block on a 727 nav unit last month. Tried contact cleaner twice, no luck. An old guy told me to use a pencil eraser on the contacts - cleared the oxidation right up. Anyone else got an old school fix that still beats the fancy stuff?

Wait, a pencil eraser on electronics?

Wait, you're telling me I've been buying overpriced Deoxit this whole time when I could've just used a pencil eraser? That's like finding out toothpaste works just as good as fancy acne cream. Bet the guy who told you that also fixes his car with duct tape and a hammer. Classic old school move that probably saves you twenty bucks and a trip to the store. Honestly, I'm kind of annoyed at how simple that is.
