brass nut, any special treatment/maintenance?

[Jimbilly]

do the slots get a little corroded and sticky? maybe polish with some really fine sandpaper folded to an edge?

I'd use a toothbrush or soft wire brush before using sandpaper to clean the grooves

Slightly off-topic, but to clean brass, anything acidic will work. For example, ketchup. Yeah, it sounds funny, but it works.   : )

1000 grit paper folded in half.  Once cleaned, apply chapstick to avoid corrosion and lube the string in the slot.

I gave up: measured carefully and ordered a Graphtech. Apparently I ordered the right one, I didn't have to touch it with a file or anything, and it stays in tune much better now.

And improves the taste.  

My Peavey T-60 came with an aluminum nut.  I've never had any issues with it.

I just remembered I have a small bottle of Flitz under the sink, I bought it to polish my Eclipse quite a few years ago
