Prevent dust getting into your audio-visual equipment’s delicate parts.

Every day: TV screens are a magnet to dust – give a passing flick as often as you can with a microfibre cloth. Wiping with a fabric softener sheet will reduce the static charge, too.

Every week: Get the vacuum out and suck dust out from the ventilation grilles of TVs, PCs, hi-fis etc. Give the casings a wipe with a just-damp cloth but steer clear of chemical cleaners.

Remote controls can be a cosy home for bacteria so give them a regular clean, too. A firm wipe with a damp cloth should do the job, or if a crust is starting to form you’ll need to get in between the buttons with a cotton bud and a mild solution of washing-up liquid.
