Regular cleaning of rubber keyboards is vital not only for maintaining their appearance and functionality but, more importantly, for ensuring hygiene and preventing the spread of germs. Keyboards are high-touch surfaces, accumulating dust, skin oils, food particles, and microorganisms over time.
Regular cleaning of rubber keyboards is crucial to prevent the buildup of dirt, dust, and oils that can degrade the material and affect tactile feedback, while also significantly reducing the accumulation and spread of bacteria, viruses, and other pathogens that thrive on high-touch surfaces. Especially in shared environments or critical settings like healthcare, consistent cleaning protects users and maintains a healthy environment.
Selecting the right cleaning supplies is paramount to effectively clean a rubber keyboard without damaging its silicone material or printed legends. Gentle solutions and non-abrasive tools are generally recommended to preserve the integrity of the keypad.
Basic and safe cleaning supplies for rubber keyboards include lukewarm water with mild dish soap, isopropyl alcohol (IPA) diluted to 70%, or approved disinfectant wipes. Essential tools are soft, lint-free microfiber cloths or sponges, and for intricate areas, a soft-bristle brush like a toothbrush.
Here's a list of safe supplies:
Cleaning Solutions:
Mild Soap and Warm Water: For general cleaning and removing everyday grime. Use a small amount of liquid dish soap.
70% Isopropyl Alcohol (IPA): Effective for disinfecting and removing oils and stubborn residues without leaving moisture. Ensure it's 70% concentration, as higher concentrations can dry out or damage some rubber over time.
Disinfectant Wipes: Pre-moistened wipes designed for electronics or medical surfaces are convenient. Always check the label for silicone compatibility.
Hydrogen Peroxide: Diluted solutions (e.g., 3%) can be used for sanitization, especially in medical environments, if the keyboard material is compatible.
Cleaning Tools:
Soft, Lint-Free Microfiber Cloths: Ideal for wiping surfaces without leaving lint or scratching.
Soft Sponges: Gentle enough for thorough scrubbing without abrasion.
Soft-Bristle Brush (e.g., old toothbrush): Useful for cleaning around keys or in textured areas.
Cotton Swabs or Q-tips: For precise cleaning of small crevices, if any exist.
Routine cleaning of a rubber keyboard is a straightforward process designed to remove surface dirt and maintain hygiene without requiring deep disinfection. This should be performed regularly to prevent buildup.
For routine cleaning, first, unplug the rubber keyboard to ensure safety. Then, gently wipe the entire surface with a damp, lint-free microfiber cloth moistened with mild soap and water or 70% isopropyl alcohol, ensuring no excess liquid enters crevices. Finally, dry the keyboard thoroughly with a clean, dry cloth.
Here are the step-by-step instructions for routine cleaning:
Disconnect the Keyboard: Always unplug the keyboard from its power source or computer before cleaning to prevent accidental input or electrical hazards. If it's wireless, turn it off.
Remove Loose Debris: If applicable (for some rubber dome keyboards with keycaps), gently shake the keyboard upside down or use a can of compressed air to dislodge any loose crumbs or dust trapped underneath the keys or in crevices. For fully sealed keyboards, this step is less critical.
Prepare Cleaning Solution: Dampen a clean, lint-free microfiber cloth with warm water mixed with a small amount of mild dish soap, or with 70% isopropyl alcohol. Wring out the cloth thoroughly so it's damp, not dripping wet.
Wipe Down the Surface: Gently wipe the entire surface of the rubber keyboard, paying attention to individual keys and any textured areas. For keypads with printed legends, avoid aggressive scrubbing to prevent wear.
Clean Hard-to-Reach Areas (if applicable): If your rubber keyboard has slight indentations or textures, use a cotton swab or a soft-bristle toothbrush dipped in the cleaning solution to gently scrub these areas.
Rinse (Optional, for soap): If using soap, wipe down the keyboard again with a cloth dampened with plain water to remove any soap residue.
Dry Thoroughly: Immediately after cleaning, dry the keyboard completely with a separate, clean, dry microfiber cloth. Ensure no moisture remains, especially if there are any subtle seams or ports. Allow it to air dry fully before reconnecting power.
Deep cleaning or sanitizing a rubber keyboard is necessary for removing pathogens, especially in environments like healthcare or food service, and for tackling more stubborn grime. This process leverages the sealed nature of silicone.
To deep clean or sanitize a rubber keyboard, use a medical-grade disinfectant wipe or a cloth saturated with an approved solution (e.g., diluted bleach or hydrogen peroxide) to thoroughly wipe down all surfaces, ensuring adequate wet contact time as per the disinfectant's instructions. For truly waterproof (IP68) models, immersion cleaning or even dishwasher cleaning (low-temp cycle, no detergent) may be an option.
Detailed steps for deep cleaning/sanitizing:
Disconnect and Activate Cleaning Mode (if available): Unplug the keyboard. Some medical or industrial rubber keyboards have a dedicated "clean" or "lock" key that temporarily disables input, preventing accidental keystrokes during cleaning. Activate this mode if available.
Pre-Clean (Optional but Recommended): Perform a routine cleaning (as described above) to remove any loose debris or visible organic matter before disinfection. Disinfectants work best on pre-cleaned surfaces.
Apply Disinfectant:
Disinfectant Wipes: Use pre-saturated disinfectant wipes (e.g., those commonly found in hospitals). Wipe down every surface of the keyboard thoroughly.
Spraying/Wiping: If using a spray disinfectant, spray it onto a clean cloth first, then wipe the keyboard. Avoid spraying directly onto the keyboard unless the manufacturer explicitly states it's safe for direct application and immersion.
Observe Wet Contact Time: Crucially, allow the disinfectant to remain visibly wet on the surface for the "contact time" recommended by the disinfectant manufacturer (e.g., 1-5 minutes). This is how the disinfectant effectively kills pathogens.
Rinse (if required by disinfectant): Some disinfectants require a final wipe with a water-dampened cloth to remove residues. Check the disinfectant's instructions.
Dry Completely: Dry the keyboard thoroughly with a clean, dry, lint-free cloth. Air dry for an extended period to ensure no moisture remains, especially in any connector areas.
Immersion/Dishwasher Cleaning (For IP68 rated keyboards ONLY):
If your rubber keyboard is specifically rated IP68 (fully submersible) or advertised as dishwasher safe by the manufacturer, it can be immersed in water or placed in a dishwasher.
Dishwasher: Use a low-temperature cycle (below 130°F / 55°C) without harsh detergents or heated dry cycles, as these can damage silicone. Some manufacturers recommend no detergent at all. Always consult the specific product manual.
Immersion: Submerge in clean water or a very mild, compatible cleaning solution. Agitate gently.
Thorough Drying is Paramount: After immersion, ensure the keyboard is completely dry, inside and out, before reconnecting it. This might involve air drying for several hours or even days in a well-ventilated area.
While rubber keyboards are durable and easy to clean, certain practices can cause damage, degrade the material, or compromise functionality. Observing specific precautions is vital to ensure the longevity and effectiveness of your keypad.
When cleaning a rubber keyboard, never use abrasive scrubbers, harsh chemical solvents like acetone or paint thinner, or excessive amounts of liquid that could seep into internal components. Avoid submersing non-IP68 rated keyboards, and refrain from using high-pressure water or extreme heat sources like hair dryers, as these can degrade the silicone or damage electronics.
Key precautions and "don'ts":
DON'T Use Harsh Chemicals or Solvents:
Avoid Acetone, Toluene, Xylene, Strong Acids/Bases, Petroleum-based Solvents: These can dissolve, swell, discolor, or otherwise degrade silicone rubber, plastic housings, and printed legends.
Avoid Abrasive Cleaners: Powders, scouring pads, or abrasive brushes can scratch the silicone surface or wear away printed key legends.
DON'T Use Excessive Liquid:
Avoid Spraying Directly: Unless explicitly stated by the manufacturer for waterproof models, do not spray cleaning solutions directly onto the keyboard. Always apply to a cloth first.
Avoid Soaking (Unless IP68): Never submerge a keyboard in liquid unless it is specifically rated IP68 and designed for immersion cleaning. Water can seep into electrical components and cause irreparable damage.
DON'T Use Abrasive Tools:
Avoid steel wool, stiff brushes, or anything that could scratch or gouge the soft silicone surface.
DON'T Use High Heat:
Avoid Hair Dryers or Heat Guns: While silicone is heat resistant, excessive, concentrated heat can deform the rubber or damage internal electronics. Air dry or use a low-setting fan from a distance.
Dishwashers: If using a dishwasher, ensure it's on a low-temperature, no-heat-dry cycle. High heat can soften or warp the silicone.
DON'T Use Bleach Concentrates: If using bleach, ensure it's diluted to the recommended concentration (e.g., 1:10 solution) as per health guidelines; concentrated bleach can be overly aggressive.
DON'T Force Drying: Do not attempt to use sharp objects or excessive force to dry crevices. Gentle wiping and air drying are best.
DON'T Disassemble (Unless Expert): Attempting to disassemble a sealed rubber keyboard can compromise its IP rating and internal components.
The frequency of cleaning a rubber keyboard largely depends on its application environment and usage patterns. In hygiene-critical settings, cleaning must be more frequent and rigorous than in a typical home or office.
The cleaning frequency for a rubber keyboard should be determined by its environment: daily or between each user in medical/food-grade settings, at least weekly in shared public spaces, and monthly for personal home or office use. Visual inspection for dirt and spills should prompt immediate cleaning regardless of schedule.
Here's a guideline for cleaning frequency:
Medical and Food-Grade Environments:
Between Each Patient/User: In hospitals, clinics, or food preparation areas where contamination risk is high, cleaning should occur after every use or between shifts, following strict disinfection protocols.
Daily: Even if not shared, daily disinfection is highly recommended to maintain sterile conditions.
Shared Public Spaces (Libraries, Kiosks, Call Centers):
Daily or Multiple Times a Day: Due to high traffic and multiple users, daily disinfection is crucial.
Before/After Each Session: Ideally, if feasible, clean before and after each user session.
Personal Home or Office Use:
Weekly: A quick wipe-down with a damp cloth and mild soap or alcohol wipe is generally sufficient to remove surface grime and minor germ buildup.
Monthly (Deep Clean): A more thorough clean, perhaps with a disinfectant, can be performed monthly or bi-monthly.
Immediately After Spills or Visible Dirt: Any spills, crumbs, or visible smudges should be addressed immediately to prevent stains or residue buildup.
Industrial/Outdoor Environments:
As Needed: Depending on exposure to dirt, grease, or chemicals, cleaning should be done as needed to maintain visibility and functionality. Resistance to harsh conditions is a key benefit here.
Regular visual inspection is key. If the keyboard appears dirty, sticky, or discolored, it's time for a clean, regardless of the schedule. Consistent, gentle cleaning not only maintains hygiene but also helps preserve the tactile feel and extend the lifespan of your rubber keyboard.
Maintaining and cleaning a rubber keyboard is a straightforward process that leverages the inherent durability and sealed nature of its silicone construction. By consistently employing appropriate cleaning solutions—such as mild soap and water, 70% isopropyl alcohol, or approved disinfectants—and utilizing soft, non-abrasive tools, users can effectively remove dirt, oils, and pathogens without compromising the keyboard's integrity. While routine wipe-downs are sufficient for daily care, deep cleaning and even immersion (for IP68-rated models) are possible for hygiene-critical environments.
