I recently learned that "Sterilex 6-Q Sanitizing Tablets" are EPA approved for restaurants to use to sanitize dishes, equipment, etc. for bacteria and viruses. This can now be obtained on the internet or at a restaurant supply. It is now called "Steramine Tablets", same ingredients as above. I now use this to wipe clean everything before it is brought into the house, including the mail, kitchen counters, etc. Google and learn more about it.
