The fumes, odors and mists come from the cleaning agents. I don't know about you, but we use commercial cleaning chemicals, one (Spartan NABC) in a spray bottle to clean walls and tile, around toilets and urinals. Another, a urine cleaner and odor neutralizer in a spray bottle to remove urine stains and odors from the floor and grout around toilets and urinals. That's where the mist comes from that can get all over your clothes. We also use a mop and floor cleaner, sometimes with bleach on the floors. Tell me that the last time you used bleach to clean you didn't come away smelling from it. I suppose if you consider restroom cleaning flinging around a damp mop then I can see your point.
