They have a new range out should your missus not like the blue/clincal small of the normal anti bacterial ones, some yellow and coconut ones available too which are also anti bacterial.
My Seven month old Has just had a Rota virus/ Gastroenteritis We was washing our hands all the time with this only to find out later that it does not Kill RotaVirus. Also Suface cleaners that Kill 99.9% of bacteria are not affective. Just a thought.
That's why the small print says bacteria not virii, also for youngsters I would imagine basic hygiene + allowing them to get ill to build up an immune system is important.
