I was surprised to use them: I usually spray little nozzles as fast as I can until the sprayer trips over itself, then use what comes out to clean it, but they just don't stop spray, I accidentally keep using it like 1/4 of a bottle and trying to see if I can mess things up. If something is so well done that I can't stop it on purpose, it gets 5 stars. They are also ideal for cleaning with hydrogen peroxide as they are darkened.
