Remote controls. We’ve got several here, as I’m sure most homes have. Now these things are meant to be held and used yes ? And hands aren’t always perfectly clean when the channel needs changing, the volume needs altering – that too is true I think. So these useful chunks of plastic can get a tad ‘unclean’. So why on earth are they not designed to come apart more easily to facilitate the easy cleaning of not only the outer case but also the inner membrane ?
