Many people have issues with the smell since it's really overpowering. I've read a few places you're supposed to dilute it, it's basically a concentrate in the bottle (weird I know that they put the sprayer on it and everything!).
I just looked at my bottle it says use 1:1 or 1:10 dilution and 1:30 dilution for light cleaning. I just looked at their online site and this page
has some specific dilutions for certain surfaces and areas of the home. There are a ton they recommend a 1:32 rate. I'm sure that would make a big difference in the smell.
Thanks for asking the question, I learned something new...been on my list to look into but I kept forgetting until I saw your post
