Hello! Apologies for paranoid post, but i am currently pregnant and moving house. My husband booked a cleaning company to clean before we move in , and they have told us they will use 'industrial strength' cleaners to clean before we move in. We will open windows and air the house after they have been, but I am worried that the cleaning products will linger somehow on surfaces and cause damage to my unborn baby. Am I being paranoid? I read articles on internet about dangers of toxic cleaning products and so a bit worried!!
