It's a good question because you definitely don't want any products or solutions brought into your home that may not be perfectly safe for occupants... your family members.
Much has gone into the formulation of cleaning products, from the detergents used for typical cleaning to deodorizers and spot and stain removers. Yes, some are powerful for specific tasks, like removing tough stains, yet these solutions are quickly rinsed out of the carpet or furniture fabric. Most companies use truckmounted cleaning machines which removes rinse water along with soils from the home and out to the work truck, to be hauled away for safe, legal disposal.
So put your mind at ease. When you use a reputable cleaning company, ask your questions on the topics that concern you but remember the professional cleaning products are as safe - or safer - than the cleaning solutions you purchase for your own use.
