I use a hospital grade equivelant at work (instead of washing hands between patients we use this - more effective than hand washing, more convenient, and more gentle on our hands believe it or not).

I have a small dettol one in my handbag. I use it when I'm in a public toilet but very few other times. I usually forget I have it. I rarely use it on DD. The only time I religiously use it at home is when someone has gastro.
