Just bought a couple $1 microfiber cloths at Staples, hoping to do something about the ever-streaky mirror in our bathroom. LOVE it already. Just a little bit of water and the thing gets everything super shiny and clean. Not just the mirrors, but the stainless steel and chrome on kitchen stuff, and the tiles everywhere. And I don't need to use any sprays or Earth-hating chemicals.
$1 microfiber cloth where have you been all my life.
This has been your PSA of the day. Happy almost Halloween!
