A ratio of 1 part chlorox to 10 parts water is the usual recommendation for sterilizing cuttings. That's what I've always used. There may be other options. It never hurts to dip your pots in the same solution and any tools you use, plus using non-soil media or heat sterilizing your planting mix if it contains soil.
