less than 5% would do this.. yuk

When you have a can of drink...do you wash the top of the can?

less than 5% do..
for the rst we put our mouths on the can, and it could have been in contact with anything, also dirt,dust, etc has landed on the can probably..
in storage who knows what has crawled in the boxes...
