There's a Wipe For That
Just like today’s mobile devices with their “Apps” designed for every conceivable function, pre-moistened wipes have been fitting niche cleaning needs for years.
Various wipes are available to clean leather, glass, whiteboards and stainless steel, as well as remove graffiti, spot clean carpets and disinfect surfaces.
Wipes can even be used on the janitors themselves. For example, cleaning or sanitizing hands between tasks or applying sunscreen or insect repellent before working outdoors.
