Leslie, I believe that phenoxyethanol is the chemical name for anti-freeze. You could probably ring an auto store and ask them to check the ingredient list on a can.

Just on the topic of bacteria in the home ... bacteria need food, water and warmth to survive and reproduce. Cleaning with hot water, rinsing all surfaces so there's no soap scunge or detergent residue, and drying the surfaces will kill more bacteria than most anti-bacterial cleaners.

The cleaning sprays with anti-bacterial agents need to 'set' for more than 30 seconds in order to be effective. Then, if they aren't rinsed completely, the surviving bacteria will feed on the residue and reproduce. I have some research on this somewhere; will post if I can find it.

(We don't use any toxic chemicals in the house, just disinfectant when scrubbing the litter trays.)
