Plenty of houses never need this. If your carpet is clean and nobody's been sick, a regular cleaning is all you're paying for, and that's what your technician will tell you.
Sanitizer earns its place in a few specific situations. A stomach bug that went through the whole family. The first cold of the school year coming home from Westwood High in September. A new baby about to spend a lot of time face-down on the living room floor. An older parent moving in. A rental between tenants, where you have no idea what the last people tracked in. In those cases, cleaning removes the soil, and the sanitizer goes after what's living in the fiber.
Landlords tend to get the most out of it. With so many people relocating in and out of Blythewood, rentals turn over often, and a new tenant who walks into rooms that smell like nothing, with no trace of the last renter's dog, starts the lease in a better mood. You also end up with a dated invoice showing the carpet was cleaned and treated before move-in, which is handy if a deposit dispute ever comes up.
Cleaning first, then the mist
The sanitizer goes on after the carpet or upholstery has been cleaned, never before. Dirt shields germs, so loose soil, hair and grime come out first and the treatment can reach the fiber directly. Your technician applies an EPA-registered product with a fine, even mist across the rooms you choose, and it works its way down into the pile and fabric while it dries.
The product is labeled to kill 99.9% of common household bacteria, and it also acts on many viruses and on mold and mildew spores. It's non-toxic once dry, leaves no sticky film, and doesn't add a perfume smell. Very little moisture is involved, so the treated rooms dry about as fast as a normal cleaning, usually within the hour. Kids and pets can go back in once it's dry to the touch.
We can treat carpet, area rugs, sofas and chairs, mattresses, and the cushions on a nursery glider. Mattresses are a good candidate after an illness, since they hold onto more than anyone wants to think about.
Timing is up to you. Most people call a day or two after the last person in the house feels better, once nobody's lying on the couch anymore. Families with allergies or a medically fragile relative sometimes put it on a schedule, every three to six months with their regular cleanings, and that's plenty. More often than that is mostly money spent for nothing.
Where the sanitizer stops
A sanitizer is a hygiene step, and it has limits. It kills what's in the carpet when it's applied, and the room starts collecting new germs as soon as people walk on it again, the same as any clean surface. It also won't fix a pet urine problem. Urine odor that's soaked into the pad needs the enzyme work described on our pet odor and stain removal page, and spraying sanitizer on top of it doesn't reach deep enough to matter.
The easiest way to get it is to add it to a carpet cleaning or an upholstery cleaning you're already booking. The tech can price it room by room at the start of the visit. Questions first? Call 803-393-7625, or send a note through the contact page about which rooms you have in mind and why.
