I use it at work (hospital ward), but not anywhere else. I wash my hands a LOT throughout the day (they are sore and dry), and when I get home - I drive - but I haven't ever wiped my groceries, nor wiped a supermarket basket or trolley, a petrol pump, garage vacuum, etc. I don't believe any of it is necessary if I wash my hands as soon as I am able to.
