Nesting help

Em

So I'm in nesting mode at 31w1d. How harmful is it to be breathing in cleaning fumes?

Most of my stuff is on the natural/less harmful side, but bleach is my best friend when it comes to the bathrooms. Which, both have poor ventilation. A mask doesn't seem to cut it. Also if there's any recommendations for alternatives to bleach that work just as well, I'd love to hear it.
