Cleaning Keyboards, Phones and Touchscreens at Work
Shared electronics get handled more than almost anything in the building, yet the usual spray-and-wipe routine can ruin them. What to use, what to keep away from them, and who should clean which device.
Why devices need their own method
Count the hands that touch a conference room’s control panel in a week, or the desk phone at a reception station, and electronics come out near the top of any office’s list of most-handled surfaces. They pick up skin oil, lotion, crumbs and coffee splashes like any desk, and they show it faster: a greasy touchscreen or a keyboard with grey keys makes a whole workspace look neglected.
The trouble is that the normal surface routine is wrong for them. Spraying a cleaner and wiping works on a laminate desktop. On a keyboard it sends liquid between the keys; on a monitor it strips the anti-glare coating; on a phone handset it seeps into the seams around the earpiece. Most damage to office equipment from cleaning comes from too much liquid or the wrong chemical, not from cleaning too often.
So electronics get a method of their own, written down separately from the general dusting and wiping, with a clear answer about which devices the cleaning crew handles and which ones it leaves alone.
Before anyone wipes a device
Three checks come first. Is the device off, locked or in a cleaning mode? Wiping a live touchscreen opens menus, changes settings and occasionally ends a call. Many room-control panels and tablets have a lock or cleaning screen; for a monitor or keyboard at a desk, switching off the display or locking the workstation is enough.
Second, should it be unplugged? For a desk phone or a mouse, unplugging is rarely needed and plugging back into the wrong port causes more trouble than it solves. For anything with a power brick under a desk, cables stay where they are. The crew wipes the outside of the device and leaves connections alone.
Third, what does the maker allow? Equipment makers publish care instructions, and they differ: some coatings tolerate alcohol, some screens only want a dry or water-dampened cloth. Keep a one-page summary for the devices your office uses most and give a copy to whoever does the cleaning.
What to use
The kit for electronics is small and gentle:
- Lint-free microfiber cloths kept only for screens and devices, washed separately from restroom and kitchen cloths
- Plain water or a screen cleaner the maker permits, applied to the cloth and never to the device
- Wipes of 70 percent isopropyl alcohol for hard, nonporous exteriors where the maker allows them, wrung so they are damp rather than wet
- A soft brush or short bursts of compressed air to lift crumbs from between keys
- Cotton swabs for the grooves around buttons, bezels and phone keypads
Work from clean to dirty: screen first, then the casing, then the keyboard or keypad, so grime from the most-handled part does not travel onto the glass. Fold the cloth to a fresh face between devices.
What to keep away from electronics
A short list of things to avoid prevents most of the damage. Never spray anything directly onto a device, including water. Keep bleach, ammonia-based glass cleaners and acetone off screens and casings; they cloud plastics and eat through coatings. Skip paper towels and tissues on monitors, because the wood fibers leave fine scratches and lint.
Abrasive pads, scouring powders and general-purpose degreasers have no place near a keyboard or touch panel. Neither do soaking-wet wipes: if liquid beads up or runs when you press, the wipe is too wet. And a fogger or whole-room spray treatment should never run with equipment uncovered.
Finally, leave the inside of every device alone. Opening casings, cleaning internal fans or vacuuming inside a computer is IT work, and so is anything in a server room, a network closet or a rack of equipment.
Device by device
Keyboards and mice: tip the keyboard and brush or blow out crumbs, then go over the keys and the surrounding frame using a damp cloth or an alcohol wipe. Pay attention to the space bar, the enter key and the mouse buttons, which take the most contact. Desk phones: wipe the handset, the coiled cord and the keypad, using a swab around the buttons and keeping liquid out of the earpiece and mouthpiece holes.
Monitors and touchscreens: dust first with a dry cloth, then wipe in straight passes with a cloth barely dampened with water or an approved screen cleaner. Conference room panels, presentation remotes and video-call controllers get the same treatment, plus the edges people grip. Check-in tablets and visitor kiosks in a lobby are wiped on the same principle, more often because strangers use them all day.
Shared office machines round out the list: copier and printer control panels, badge readers, time clocks and the keypads on microwaves and coffee machines. Headsets are the exception to sharing. Ear cushions and microphone covers are personal, so the simplest rule is one headset per person, cleaned by its owner.
Reading the warning signs
Devices show cleaning damage before they fail. A cloudy or rainbow-tinted patch on a monitor usually means a coating has been attacked by the wrong cleaner. Keys that stick or feel gritty point to liquid or crumbs underneath. Faded lettering on key tops and handsets is a sign the wipes are too harsh or too wet. When any of these shows up, stop and check the product and method against the maker’s guide before the next round.
Ask whoever cleans the devices to report problems rather than work around them: a cracked screen, a loose cable, a phone with no dial tone. A short note to the office manager the next morning gets the equipment fixed and keeps the crew from being blamed for damage it found, not caused.
Who cleans what, and how often
The cleanest split is by ownership. The cleaning crew handles shared equipment in common areas and at hot desks, on the exteriors only and following the list the office provides. Employees look after their own laptops, phones and personal headsets. IT owns anything that needs opening, unplugging or moving, along with server rooms and network closets. Write the split into the task list so nobody wipes a device they were never meant to touch.
Frequency follows use. Conference room panels and remotes in rooms booked daily, lobby kiosks and hot-desk keyboards suit a nightly wipe. Desk phones and keyboards at assigned desks usually need a weekly pass, or nightly if the office asks for it. On busy days, a day porter round can wipe lobby kiosks and meeting-room panels between sessions.
Ascent Cleaning crews wipe electronics with a dampened cloth instead of spraying them and follow each maker’s care guide, as part of janitorial service or with the products you approve under green cleaning. List the devices you want covered when you request a quote, and that list goes into your task sheet.
A few useful answers
Common questions.
Can disinfecting wipes be used on a keyboard?
On most keyboards, yes, if the maker allows it. Many makers accept 70 percent isopropyl alcohol wipes on hard exteriors. Wring the wipe so it is damp rather than wet, keep it away from openings, and avoid bleach-based wipes, which can discolor key tops.
Should cleaners touch employees' laptops and personal phones?
Usually not. Personal devices stay with their owners, who clean them. The crew handles the shared equipment on the office’s list: hot-desk keyboards, conference panels, desk phones in shared spaces, kiosks and copier controls.
What is the safest way to clean a computer monitor?
Switch the display off, dust it with a dry microfiber cloth, then wipe in straight passes with a cloth barely dampened with water or a screen cleaner the maker permits. No ammonia glass cleaner, no paper towels and no spraying the screen.
How often should a conference room touch panel be cleaned?
Nightly in a room booked every day, with a midday wipe added when meetings run back to back. A room used once or twice a week can go on the weekly round.
Will Ascent Cleaning wipe the shared electronics in our office?
Yes. Shared devices you list are wiped on each visit with a dampened cloth rather than a spray, following the maker’s care guide. Personal devices and anything inside equipment stay off the list.
