We have become much more conscious of cleaning in these pandemic times (Covid-19 Corona Virus times). It is lock-down day 57 here in South Africa. I am spending more time when I get into the office to clean my workplace, and also my smartphone. I have also been keen to know if I am doing it right. The Cleanipedia portal has some very useful tips for cleaning, I have been spraying anti-bacterial sprays on tissues/paper towels when cleaning my electronic devices. It's not too far off the mark, but it is great to get some extra insights.
Cleanipedia has the following suggestions to clean your smartphone. See also their tips on cleaning your laptop, keyboard and other electronic devices.
