Engadget sets out cleaning guide for secondhand electronics
The guide recommends switching devices off, using suitable tools and allowing them to dry fully before use.
Secondhand electronics should be switched off and unplugged before cleaning, according to a guide published by Engadget. The advice covers devices including phones, laptops, earbuds, cameras, turntables, smartwatches, televisions and monitors.
Engadget recommends a soft microfibre cloth for removing dirt and fingerprints, particularly from screens. Compressed air can be used around ports and vents, while soft-bristled brushes are suited to delicate components and intricate parts such as turntable needles.
The guide advises against cleaners containing chlorine, peroxide, solvents or ammonia, which may damage internal components or protective screen coatings. Isopropyl alcohol should be used cautiously, if at all, because guidance varies and compatibility depends on the device and its manufacturer’s instructions.
Small amounts of moisture should be kept away from openings, and devices should be allowed to air dry completely before being switched on again. The advice also extends to accessories such as cases, chargers, cables and smartwatch bands.
For ongoing maintenance, Engadget suggests cleaning phones weekly, with daily wipe-downs, earbuds at least monthly, and laptops every three to six months. Television screens and monitors are recommended for cleaning every two to four weeks.
The guide presents cleaning as part of giving used technology a second life, potentially helping owners save money while extending the useful life of products. It also mentions portable ultraviolet sanitisers for smaller items, while noting that their effectiveness and suitability can vary by device, contaminant and product.
