The zep cleaner uses DIETHYLENE GLYCOL MONOBUTYL ETHER as an active chemical. It is reasonably safe product however it takes 2 or three days to completely break down unlike Chlorahexidine or quantryammonia compounds (F10). I will not say it is safe to use as I am actually unsure, the lethal dose (50%) for rats is 6550 mg/kg and bleach is 8910 mg/kg.
Personally based on the LD50 ratings I'd avoid it. Both chlorahexidine and F10 are good alternatives to it. I don't like using bleach either as it toxic and must be so carefully washed away (or everything left in the sun for hours) I am in the process of switching to F10 as it is more stable than chlorahexidine and does not need to be mixed just prior to use.
