Honestly... I mix everything. I'm fine. Never passed out. Never got chemical burns. I do a small cap of bleach, Mr clean unstoppable, and vim often and none are the same product. Buuuut my house be smelling clean and amazing, smell lasts, and the floors actually feel clean. Some people clean but the floors feel gross and sticky or they don't rinse properly or something idk. Long as your careful about breathing it in. And when I use bleach it's usually a tiny cap full.
