Consumer Reports emphasizes the importance of routine maintenance to keep electronics like phones, TVs, and computers functioning optimally. Common issues often stem from dirt and debris accumulation, particularly in charging ports and speakers. Home expert Courtney Lindwall advises against using sharp objects for cleaning, recommending softer tools such as cotton swabs or makeup brushes instead. For screens, using microfiber cloths is essential, as harsh materials like paper towels can scratch surfaces. Nicholas De Leon from Consumer Reports highlights that food particles can hinder keyboard performance, suggesting that users should avoid eating over their devices. Before cleaning, it's crucial to power down and unplug the device, and to consult the owner's manual for specific guidelines. For those who prefer professional help, tech repair shops like the Apple Store and Best Buy offer cleaning services.
