Taking them to the cleaners

I recently got an email from a reader about the use of cleaning products in the house - YAY, my favourite subject (no, seriously). Don't know about other dads but I keep seeing these ads for all purpose cleaning products in the house that promise to remove 99.99% of all germs. Sounds great, eh? Until you realise that whatever kills 99.99% of all bacteria must be pretty lethal all round. So I'm not sure I prefer my little man to lick a surface with some leftovers from the cleaning product vs picking up the germs that were there naturally.
