How to sanitize a phone: Step-by-Step

Tools:

E-Cloth
Disinfectant wipes (with at least 70% isopropyl alcohol)
Cotton swabs
Mild dish soap
Water

Proper Preparation

Turn off your phone and unplug it from any chargers.
Remove the case if possible so you can sanitize all surfaces.

Cleaning Process

Use a disinfectant wipe containing at least 70% isopropyl alcohol. Gently wipe the front, back, and sides of your phone.
Avoid moisture getting into any openings; steer clear of applying the solution directly to the device.

Allow to Dry

Let your phone dry completely for a few minutes before turning it back on.
Reattach the case only when it is also dry.

Precautions:

Disconnect Power & Avoid Moisture Exposure

Ensure your phone is powered off and unplugged from any chargers to prevent electrical issues during cleaning.

Use Minimal, Approved Cleaning Fluids

Opt for a small amount of manufacturer-approved disinfectant to avoid damaging sensitive components.

Avoid Direct Liquid Application

Always apply any cleaning solution to a cloth first, rather than spraying it directly onto the phone.

Be Gentle with the Device

Use a soft microfiber cloth and gentle motions to prevent scratches or physical damage.

Mind the Ports and Openings

Clean carefully around charging ports and buttons to stop moisture from seeping into internal components.

Avoid Harsh Chemicals and Abrasives

Stick to mild disinfectants; harsh chemicals can strip coatings and damage the phone’s finish.

Check Manufacturer's Cleaning Guidelines

Refer to your phone’s manual for any specific warnings or cleaning instructions to keep your warranty intact.

How to Correctly Sanitize The Phone: Extra Tips

Turn Off and Unplug the Device

Ensure Safety: Always switch off your phone and disconnect it from any cables before cleaning; this reduces the risk of electrical issues.
Prevent Short Circuits: A powered-off device minimizes the risk when in contact with any moisture from cleaning solutions.

Title

Use a Safe, Alcohol-Based Cleaner

Select the Right Product: Opt for a 70% isopropyl alcohol solution which is effective in eliminating germs without harming your phone's materials.
Apply with Caution: Dampen a microfiber cloth slightly; never spray the liquid directly on the device to avoid seepage into openings.

Title

Avoid Excessive Moisture and Pressure

Gentle Cleaning: Use soft, light strokes when wiping your phone to prevent pushing liquid into sensitive areas like ports and speakers.
Focus on Surfaces: Concentrate on cleaning the exterior surfaces while avoiding aggressive scrubbing that might dislodge internal components.

Title

Follow Manufacturer’s Guidelines

Consult Instructions: Read your phone’s manual or manufacturer recommendations to ensure that the cleaning methods and solutions used are safe and won’t void warranties.
Stay Updated: Manufacturers might update guidelines over time, so keep an eye on any new instructions or cleaning precautions.

Common Mistakes When Sanitizing Phone

Using Harsh Chemicals on Your Phone

Many people reach for bleach or strong cleaning sprays, not realizing these can strip the screen’s protective coating.
Alcohol wipes might seem like a quick fix, but using formulas with over 70% alcohol or added chemicals can lead to discoloration or damage over time.
Always check the manufacturer’s guidelines to ensure that the product is safe for your device.

Overlooking Small Crevices and Ports

Ignoring tiny spaces like headphone jacks, charging ports, and speaker holes can allow dust and bacteria to build up.
Using compressed air sparingly and a soft brush helps remove stubborn particles without causing damage.
A regular, gentle clean keeps these areas functioning properly and minimizes the risk of moisture intrusion.

Not Letting Your Phone Dry Completely

Wiping down your phone without giving it a chance to dry can lead to moisture being trapped against sensitive components.
After cleaning, use a dry, soft microfiber cloth and allow the phone to air dry before using or putting it back in a case.
This ensures that residual cleaning solution doesn’t seep into any openings, potentially causing long-term damage.

How Often to Sanitize Phone

Recommended Frequency

Daily Sanitization: Clean your phone at least once every day. This routine helps prevent a build-up of germs from constant handling throughout the day.
After High-Exposure Situations: If you’ve been using public transport, dining out, or in any crowded space, give your phone a quick wipe once you’re back home.

Why Daily and Post-Exposure?

Constant Contact: Your phone is one of the most frequently handled items, making it a hotspot for bacteria and viruses.
Minimized Health Risks: Regular cleaning reduces the chance for harmful microbes to accumulate, keeping you a step ahead in preventing illness.
Simple Habit, Big Impact: Incorporating a daily cleaning routine not only keeps your device hygienic but also offers peace of mind in a busy world.
