I have a cleaner who comes once a week.
She obviously never smokes in the house, or takes smoke breaks while she’s cleaning, but I know she’s a smoker because I can smell it on and around her while she’s in the house.
I work from home so I notice the smell while she’s here, but DD is always at nursery while she’s here. By the time the cleaner has left, and DD is back home, I can’t smell smoke any more.
Could this still be a health risk to DD? I know it must be a minuscule amount, but tiny smoke particles must be lingering around the cleaner and maybe settling on the floors and furnishings in our home.
