Have you thought about how clean – or not – the surfaces you leave your accessories on when travelling are? The tray tables and seats of public transport are all hotbeds for germs. Cue PhoneSoap, a portable device that sanitises phones, tablets, keys and headphones. There’s no actual soap or bubbles involved, just UV-C (germicidal wavelength) radiation that eradicates bacteria. Available in three sizes, from Dh185 at phonesoapme.com.
