Also worth stripping the lantern and giving a quick spray with high temp paint or plastikote (I know, I said it before). A tiny drop of your wife's perfume in the tank or on the top of the hood will stop any odour but keep your wicks trim and tidy, don't burn too high and there should be very little smell.
If you've not stripped one down before, the ring on the top is not for hanging, pull it while holding the tank to raise the hood which allows the globe to tilt back for easy removal and cleaning/wick trim/change or spraying with paint. The globes on the bigger lanterns will be fragile so careful how you handle them and wash in warm water.
Worth getting in a stock of wick, buy by the metre off ebay, its cheap enough.
