Ur right about copper corroding fast. Before I turn on the iron, I take out the tip hold it in a vise and brush it like hell with a wire brush (brass wires). Then, soon as it's hot, i flow solder all over the tip - it wets really good after the brush up - & flick off the excess. Seems to minimise the rate of corrosion by protecting the core somewhat.
