How we test for touchscreen hygiene
After swabbing 30 tablets, 30 phones and 30 office keyboards and sending, we received the stomach churning results you see above. On one particularly dirty tablet, we found a swab count of 600 units per swab for Staphylococcus aureus, which can cause a severe stomach bug.
To put this figure in context, the Health Protection Agency classes any count of between 20 and 10,000 units for Staphylococcus aureus as a potential risk. By comparison, a typical toilet seat we tested had a Staphylococcus count of less than 20 units.
“A count of 600 on a plastic device of any sort is incredibly high,” says James Francis, the microbiologist who carried out our testing.
“In the food industry, if we found those levels of bacteria from a hand swab of a food handler, they’d have to be taken out of the workplace and retrained in basic hygiene.”
How to keep your smartphone and tablet clean
Now you’ve seen our tablet-toilet seat comparison, there’s a strong chance you’ll want to give your iPad a scrub with a soapy sponge. Don’t do it – you’ll risk damaging your touchscreen device with water.
Thankfully, there are some easy and safe methods for keeping your smartphone clean:
Do – hygiene tips
- Unplug any cables before you start cleaning.
- Use a damp, soft, lint-free cloth to wipe clean.
- Use a dry lint-free cloth to remove streaks and dry your phone.
- Avoid getting moisture in any openings or ports.
- Disinfect using specially-designed screen wipes. Apple advises against using alcohol-based cleaners on iPads or iPhones as these can damage the screen.
Don’t – hygiene tips
- Use a scratchy or abrasive material, as this would leave permanent marks on the screen.
- Use an aggressive detergent that could erode fragile surfaces on phone or tablet touchscreens.
- Use alcohol-based cleaners on iPads or iPhones, according to Apple’s advice for these products.
- Only rely on wiping your phone on a shirt sleeve or dry cloth.
