TSC (or Farm & Fleet, I suppose also) carries "21st Century" Kerosene Additive. The stuff comes in about 5 different scents (we got pine) and an 8 oz. bottle treats up to 80 gallons of kero. It cost about $3. "Cleans the wick, reduces odor, and disperses water" (helps save your wick). I imagine if you are storing kero in the cold, and bring it into the house, you might get some condensation in the works...
