Soap nuts and Rockin Green
Tell me about soap nuts. I know nothing. What are they? Are they actual nuts, grown on a tree? How do they work? How do they clean? Does it lather or bubble up? What are they like on stains? Do they catch and snag on clothes? Does it wear out, or wear down... how do you know when to change it? Can you soak with it? Does it have a smell? How many do you need for a washing machine, does it matter what size the machine is?
And what is Rockin Green? Is it a detergent or is it like a soap nut? Apparently you can soak MCNs in it, and it doesn't break it down???!!???
