Re-using pots - how do you sterilize?

[Fairorchids]

Ray, this is from Chlorox web site:

Some quick background: The sodium hypochlorite active in liquid bleach naturally degrades into salt and water in the bottle. The major factor determining the rate of decomposition is temperature. The higher the temperature the faster the active is lost; older product also decomposes more rapidly. We even compensate for this by adding more bleach during our summer production. Generally, we say that under average storage (~70°F) conditions, bleach has a 12-month shelf life.
