Ozone? Could you please elaborate? What's with storage that increases ozone exposure?

Electric motors in a garage or storage room (e.g. for a heating system) might be a source of ozone, or sunlight on oils and solvents. The storage itself isn't the problem, it's the higher-than-average level of ozone in typical places rarely used bicycles might be stored.
