So, the way to clean copper coins in households that don't use
Coca-Cola is to swallow them ?
Does that work for dirty contacts on motherboards, too ?
Sorry ! Couldn't resist. :)
Actually, the acid properties of Coca-cola are well known. Together
with most fizzy soft drinks it contains a range of acidic materials,
including, but not restricted to, orthophosphoric acid, fumaric acid,
tartaric acid, citric acid (lemon flavour), and so on. If it wasn't
acidic the compressed carbon dioxide that makes the bubbles would all form
soluble carbonate, and it would no longer fizz.
Trust me, I am a chemist.
It's not the acidic properties of soft drinks that concern me too much,
it's the other "flavour" ingredients. I do consulting work for a company
or two that formulate "flavouring mixtures" for foodstuffs and beverages.
If they weren't used very diluted in the final product, some would have to
be labelled as toxins, corrosive, carcinogens, teratogens, mutagens and so
on. Many would have to be declared as "dangerous goods" for transport by
road, rail, air and sea. Even some of the colouring materials used are
nasty in the pure state.
I should explain: Dangerous Goods, Poisons, Occupational Health and
Safety is my consulting speciality, and mostly concerns compliance with
these families of regulations, both in Australia and internationally. I
compile the material safety data sheets for products like these - it is my
job to find out about the nastiness of ingredients.
I have almost stopped buying "prepared" foods.
Regards,
Ron
