 Eyes, okay. Okay, yeah. I think you need to do that really with any... I mean, if you squirt lemons juice in your eye, you've got a problem. That's it. But probably the most dangerous thing, and it's not really dangerous, but if you sprayed it on a slick floor and left it, it will be slippery. So you want to wipe it up because slippery is still, you know, it can cause problems. So wipe it up on surfaces, leave it in cracks and crevices, and you'll be a very happy orange guard user.
