We clean surfaces before we disinfect them

Every sanitization visit starts with cleaning

A sanitization visit has two passes, and the order matters. First we clean the surfaces people touch: door handles, light switches, stair railings, the fridge handle, faucets, the flush handle on every toilet. That pass lifts off the grease and skin oil sitting on top. Then the disinfectant goes on the clean surface and stays there. Wiping it straight off is the usual mistake, because most products need to stay wet for several minutes to do their job.

Skip the cleaning pass and the disinfectant ends up working on the dirt instead of the germs under it. A film of cooking grease on a cabinet pull, or soap scum around a faucet base, soaks up the product and shields whatever is underneath. The surface smells clean and looks wet, but the germs in that film are still there. That is why a spray-and-wipe on a dirty kitchen does far less than people think.

When the work is finished, there is not much to see. Counters dry without streaks and handles do not feel tacky under your hand. We use eco-friendly, non-toxic products, which matters in a house where a toddler crawls across the kitchen floor or a dog licks the cabinet doors. You should not walk in afterward to a heavy chemical smell. Fabric on a sofa or a rug is a different job, handled as carpet and upholstery cleaning.

• Grime cleaned off before any disinfectant goes on
• Door handles and light switches in every room
• Kitchen counters and appliance handles
• Faucets and flush handles in each bathroom
• Disinfectant kept wet for its full contact time

Older Canton homes need more careful disinfecting

Much of the housing around Canton is older, from center-entrance colonials and Capes to raised ranches and split-levels. Older houses come with older surfaces. An original brass doorknob or a stair rail worn down to bare wood holds dirt differently than a new laminate counter does. A hard, sealed surface can be disinfected. A porous one, like raw wood or old unsealed grout, soaks up dirt and product together. It needs a longer scrub first.

Old finishes are also easy to damage. Brass hardware dulls and spots when a harsh product sits on it, and the painted trim in an older colonial can soften or lift. So before we treat a surface, we look at what it is made of and how worn it is. When we are not sure, we test the product on a hidden edge first. Skipping that check is how a cleaning visit turns into a repair bill.

Bathrooms in older homes bring their own trouble. Plenty have a weak exhaust fan or none at all. After a shower on a humid July afternoon or a closed-up February morning, the walls and fixtures stay damp for hours. The caulk line along a tub and the floor around a toilet base collect grime fast in that dampness. We scrub and dry them by hand before the disinfectant goes on, because a surface still wet from steam thins the product.

Germs spread faster in a shut house

From late fall into spring, a Massachusetts house stays shut tight. The storm windows are down and the heat is running. Everyone spends more time inside and touches the same handful of things: the thermostat, the fridge door, the TV remote, the bathroom light switch. When a stomach bug or a cold gets into a house like that, some of it travels by hand, through those surfaces. Airing the place out is not really an option in January.

After an illness runs through a house, we plan the route before we start. We begin in the rooms the sick person stayed out of and finish in their bedroom and the bathroom they used. A fresh cloth goes into each room, so nothing gets carried from one room into the next. Every handle and switch along the path from the bed to the bathroom gets its own pass. This works best once everyone is well again, so a surface we just treated is not touched by someone still sick an hour later.

Disinfection has a limit worth knowing. It kills the germs on a surface when we treat it, and it does not keep working for weeks after we leave. The next person who comes in from the driveway and grabs the door handle starts the cycle again. It makes the most sense at set moments, like the week a newborn comes home or before a parent moves in for the winter.

We disinfect offices and shops after closing

In a business, the surfaces that matter are the ones strangers share. At a shop counter that means the card reader, the pen on its chain, the glass and the front door push bar. In an office it is the break room, where the coffee maker buttons and the microwave keypad get pressed by a dozen people before lunch. Those spots get the same two passes as a house: clean first, then disinfect.

It rarely works to disinfect a shop during business hours. The product needs to sit wet on a surface for its full contact time. That is hard to manage when a customer reaches for the counter a minute after it was sprayed. Evening and weekend visits solve that. With the space empty, every surface can stay wet as long as the label calls for. Your staff come in the next morning to counters that are dry and ready to use.

An after-hours visit means handing someone a key or an alarm code, so it matters who shows up. Everyone we send has been background-checked and trained. We are licensed and insured, and the company is bonded, which property managers tend to ask about. Every job is covered by our satisfaction guarantee, so if something on your walkthrough the next morning looks wrong, call us and say so.
