Hello,
my mom has always thrown down the sink drain the coffee grinds after
making the coffee, beliving that it helps to mantain the drain free of
rust and germs, but a friend doesn't belive this. in my opinion, it is
true because the coffee grinds have a certain level of antioxidants.
to what point is this true?

Thanks
Cheers,
Nadia
