Cleaning High-Touch Surfaces Like a Pro


    High-touch surfaces — door handles, light switches, faucets, remotes, phones, keyboards — are the spots many hands contact, so they’re where germs most easily pass from person to person. To keep them clean, wipe them regularly with soap and water or an all-purpose cleaner (daily in shared spaces, more often if someone’s sick), and switch to a proper disinfectant only when there’s illness in the home. Just as important: wash your hands often with plain soap and water, and don’t overuse antibacterial products, which can encourage resistant bacteria. Here’s a room-by-room and surface-by-surface guide.



      What are high-touch surfaces?

      A high-touch surface is any area lots of people touch with bare hands — door handles, stair rails, light switches. They carry more risk because germs pass easily from hand to hand. An object that can transmit disease this way is called a fomite; how likely a surface is to act as one depends on its material and the germ involved.

      How long do germs survive on surfaces?

      Not every surface is a good home for microbes. Copper is naturally antimicrobial — little survives on it for long — while a damp sponge is a prime breeding ground. Viruses generally last longer on hard, non-porous surfaces (plastic, steel) than porous ones.

      A 2020 study in the New England Journal of Medicine measured how long the COVID-19 virus survived on various surfaces under lab conditions:

      SURFACE
      TIME SARS-CoV-2 SURVIVED (HOURS)
      Copper
      10-20
      Cardboard
      20-60
      Stainless steel
      45-80
      Plastic
      60-90+

      Important context: while the virus can persist on surfaces, real-world contact tracing showed fomite transmission of respiratory viruses is uncommon. By 2021 the CDC concluded surface transmission is not a common way COVID-19 spreads — it’s mostly airborne. One Massachusetts study of public surfaces found the odds of catching COVID from a fomite were under 5 in 10,000. So clean high-touch surfaces as good hygiene, but ventilation and handwashing matter more for respiratory illness.

      Why high-touch surfaces still matter

      Even though fomite transmission of COVID is low, it isn’t the only concern — plenty of other germs spread readily on surfaces. Cold sores, hand-foot-and-mouth disease, norovirus and other stomach bugs, cold and flu viruses, and more can survive and transfer on high-touch points. So keeping them clean is worthwhile in any season, not just during a pandemic.

      High-touch surfaces in offices

      Common high-touch spots in workplaces:

      • Desktops
      • Computer mice, trackpads, keyboards
      • Chair arms and backs
      • Lunchroom coffee machine and microwave
      • Phone headsets and buttons
      • Copier lid and control panel
      • File cabinet drawer pulls

      These should be cleaned regularly. If you’re working in or visiting one, also mind what you touch and wash your hands often — plain soap and water kills most germs, or hand sanitizer with at least 60% alcohol if soap isn’t available.

      High-touch surfaces in schools

      Kids aren’t known for sanitary habits, so schools spread illness easily. Common spots:

      • Drinking fountains
      • Desks, chairs, and computers
      • Bus handles and seatbacks
      • Shared, hands-on learning materials

      Janitorial teams should give these extra attention, and students and teachers can help by being mindful of what they touch and washing hands frequently.

      High-touch surfaces in hospitals

      Hospitals are generally more attuned to fomites, but they also have more — and more dangerous — germs circulating, so they take extra care. High-touch areas include:

      • Bed rails and frames
      • Movable lamps and IV stands
      • Tray tables
      • Bedside tables and chairs
      • Blood pressure cuffs

      Most hospitals follow strict cleaning protocols, but as anywhere, washing your hands regularly is wise while inside one.

      High-touch surfaces at home

      Most new illness comes in from outside, but homes have high-touch surfaces too — and cleaning them helps stop one family member’s illness from spreading to everyone. Common ones:

      • Light switches
      • TV remotes
      • Tabletops and counters
      • Door and appliance handles
      • Faucets
      • Phones and tablets
      • Play areas

      An all-purpose cleaner is usually plenty for daily cleaning. If someone’s sick, switch to an EPA-registered disinfectant for the duration of their illness and a day or two after, used per the label (and never mixed with other cleaners).

      How to clean high-touch surfaces

      For everyday cleaning, soapy water or an all-purpose detergent on a microfiber cloth is sufficient — apply, then wipe away with clean water. Avoid using antibacterial or antimicrobial products on everything all the time, which can encourage resistant bacteria. Save disinfectants for when someone in the home is ill.

      Pro Tip: everything you need to know about toxic vs. non-toxic cleaning products.

      High-touch surface cleaning checklist

      HIGH-TOUCH SURFACE
      CLEANING METHOD
      Door handles and push plates
      Spray cleaner on the handle/plate and wipe off the excess with a clean microfiber cloth.
      Light switches
      Spray a little cleaner onto a cloth (not directly onto the switch, to keep liquid out of the electrics) and wipe the plate; dry with a clean cloth.
      TV remotes
      Remove the batteries, wipe all buttons and surfaces with a slightly damp cloth, and dry fully before reinserting batteries.
      Computer mice, keyboards, trackpads
      Power off and unplug, apply a little 70% isopropyl alcohol with a lint-free cloth or swab, and dry thoroughly before powering back on. Don’t spray liquid directly on electronics.
      Desks, chairs, and tables
      Spray with an appropriate cleaner and wipe off the excess with a microfiber cloth.
      Faucets
      Spray with an appropriate cleaner and wipe with a microfiber cloth (mild soap and water on special finishes).
      Children’s toys
      Use a cleaner labeled safe for food-contact/toy surfaces, follow the label, and rinse with clean water afterward since kids mouth toys.

      Final thoughts

      High-touch surfaces are easy to overlook but worth including in a regular cleaning routine, at home and at work, to limit the spread of illness. The risk of catching COVID specifically from a surface is low, but other germs spread on surfaces readily, so cleaning them matters year-round.

      Two balanced habits go furthest: don’t over-disinfect (everyday soap and water or all-purpose cleaner is enough most of the time, and constant antibacterial use breeds resistant bacteria), and wash your hands often with plain soap and water — gentler on skin, effective against viruses, and no need for antibacterial soap.
