I have nickle-plated hardware on my kitchen cabinets: hinges, door-pulls,
knobs, etc. The hardware has started to tarnish a bit, especially those
pieces that are used often. The knob on the drawer where I keep my knives
is turning dark gray in color and I want to polish it up a bit.
Unfortunately, I don't know how to go about this without ruining something.
What is the best way to go about polishing my knob?
