How to clean your smartphone

Community Manager





Please Note: Do not use compressed air. Don't apply or spray bleaches, cleaners or liquid solutions directly onto your phone. Never submerge your device in cleaning agents or use soap, water or vinegar.


Washing your hands well and regularly is a crucial way to prevent the spread of germs, but many harmful substances can live on the surfaces of devices for hours or even days. This is especially problematic when we consider the amount of times we touch or lift a phone to our faces, or even pass it to others to take photos or calls.


According to a study done by research company Dscout in 2016, we touch our phones about 2,600 times a day. Tapping, swiping, moving and lifting are all examples of physical contact with your device – and contact with whatever germs are living on its surfaces. Keeping it clean should be part of your general maintenance routine all year round. 


How to clean your Galaxy device

Instructions applicable  for: Galaxy smartphone, Galaxy tablet and Galaxy Watch (excluding watch strap). Not applicable for Galaxy Buds/ Buds+, keyboards, plastic straps for wearables or other Samsung products.


  1. Wash and dry your hands thoroughly before starting
  2. Turn off your device and unplug any charger
  3. Remove any covers, cables and accessories 
  4. Find a clean, soft microfiber cloth. Dampen the corner with a small amount of distilled water or disinfectant
    • Use either a hypochlorous acid-based (50-80ppm) product or alcohol-based (more than 70% ethanol or isopropyl alcohol) product
    • Avoid harsh chemicals that have not been approved to use on electronics. They could wear down your display's coating layer
  5. Gently wipe any glass, ceramic or metal surfaces on the front and back of the device, avoiding openings and gaps
  6. For guidance on cleaning accessories like cases, seek advice from the manufacturer

I must admit that I have cleaned my screen today using this procedure (Even though I was already well aware). 


Just some advice to not cheap out on water, it might sound a good idea but you will never get a final result that's just as good as with a specialised cleaning liquid for screens (Keyword: For screens :winking-face: ). It might be a bit more expensive but its definitely worth it! :smiling-face:

Particularly important during Covid-19   but you should regularly  clean your phone anyway to minimise the risk.   of course make sure you following the best advice  and do not cut corners.   We now hear about methods such as UV Light Sanitisers but not sure if I'm sold on that.

I've been using window cleaners with ethanol or glycerin for ages and I'd simply wash the case with soap and water.

For me, I wash it occasionally with wet cloth and water

I like this!👍


Is it safe to use alcohol-based product (70%) to clean the galaxy S10 since it has the fingertip sensor on its back?


I do not think so, but I am willing to hear more from Samsung.

@luissthefirst  yes think it is ok to use alcohol-based (more than 70% ethanol or isopropyl alcohol) product on S10,   just do not apply on a microfibre  cloth and not directly .  It is also important not to use too much pressure.  Just a need to be a bit careful with practices when we are still dealing with Covid-19  (become more of a concern again in the Uk/Europe lately). 


Of course there are alternative cleaning solutions, just to point that the S10 range and successors are highly water resistant with Ip68 rating, though that is not the same thing as being waterproof. 


This is so useful, just cleaned my A10 following these steps 🙂
