So Very Tiny

Samsung is coming out with a new washer that uses silver to clean clothes, according to Reuters:

The South Korea-based manufacturer said in a statement that its new front-loading washer, which will start selling in the United States this month at a suggested price of up to $1,399, injects tiny silver ions into the tub during the wash and rinse cycles to sanitize clothes.

That's great, but "tiny" silver ions? Why not large silver ions? Wouldn't they get the clothes even cleaner?

I love that phrase, though--"tiny ions." It's very evocative somehow.

But surely the washer doesn't really "inject" the ions. The washer doesn't have an "ion injector," does it? Sounds like something you'd see at Los Alamos. They must mean that some part of the tub is just made of silver, right?
