The Most-Touched Surfaces in Your Building's Common Areas: 5 Areas to Disinfect Regularly

In any residential building, dozens of people touch the same surfaces every day: doors, elevators, stair railings, intercoms. These contact points are also where fingerprints, germs and residue accumulate fastest — yet they are often the areas a regular cleaning pass covers most quickly.

Here are the 5 most-touched areas in your building's common spaces, and how to make sure they stay clean between visits.

1. Door handles and entry push bars

Front door handles, hallway door handles and community room door knobs are touched by nearly everyone entering or leaving the building. They show visible fingerprints within hours.

How to treat them properly:

- Wipe them down on every visit with a clean cloth and a disinfectant suited to the material (stainless steel, brass, aluminum)

- Pay special attention to panic bars on emergency exits — heavily used but often forgotten

- Avoid abrasive products on metal finishes, which lose their shine over time

A regularly disinfected handle sends a strong signal to residents: this building is cared for.

2. Elevator buttons and control panels

In a building with elevator, every resident presses the same buttons several times a day: the call button on each landing, the floor buttons, sometimes door open and close. It is one of the most concentrated contact points in the building.

Best practices:

- Clean the buttons and touchscreen (if any) on every visit, with a lightly damp cloth rather than a soaked one to protect the electronics

- Do not forget the landing call buttons on every floor, not just inside the cab

- During flu season, a higher frequency on these specific points is greatly appreciated by residents

3. Stair railings and handrails

Stair railings are touched with fingertips, palms, or gripped firmly — especially by children and seniors. They collect not only fingerprints but also an oily film from hands.

To keep them clean:

- Wipe the full length of the railing, including curves and joints, not just the most visible section

- Match the product to the material: varnished wood, metal and plastic do not have the same needs

- Check the sturdiness of the brackets at the same time: a wobbly railing is a fall hazard before it is a cleanliness problem

4. Intercoms, keypads and fob readers

The entry intercom, the parking keypad, the garage fob reader: these electronic devices are handled by everyone, sometimes with dirty hands (after parking, after taking out the trash), and they are fragile.

What to do:

- Use a soft, lightly damp cloth and a disinfectant without aggressive alcohol to avoid damaging screens and keys

- Never spray directly onto the device: apply the product to the cloth first

- Clean the frame and the surrounding wall too, often marked by fingerprints that missed the keys

5. Light switches and garbage room handles

The garbage and recycling room is a mandatory stop for every resident, and its light switches, door handles and bin lids are among the most contaminated surfaces in the building.

The protocol to follow:

- Disinfect switches and handles on every visit, without exception

- Provide the cleaning team with gloves dedicated to this area, to avoid cross-contamination with the rest of the common areas

- Report any damaged lid or latch: a bin that does not close properly quickly becomes an odour problem

Make it a habit, not an exception

Disinfecting these 5 areas takes only a few minutes per visit when it is built into the routine. The most common mistake is leaving it to the team's memory: add these contact points to your written cleaning plan, with a clear frequency.

A building whose touched surfaces are visibly clean inspires confidence in residents, visitors and prospective tenants. It is a detail that matters far more than most people realize.
