TV units are susceptible to dust, dirt and cobwebs if not cleaned or maintained regularly. Set up a weekly routine to clean out and rearrange your TV units, make sure the wiring is neatly coiled and organised and the cabinets are not cluttered with too many accessories. Use a moderately-damp cloth to get rid of stubborn fingerprints, stains and grime, or material-specific cleaning solutions for materials such as wood and glass.
