Problem: Screen smudges or fingerprints can ruin anything you do on your computer — from completing important work to unwinding and anything in between. Solution: The OXO Sweep & Swipe laptop cleaner is a super compact and efficient accessory that will keep your computer looking brand new on the cheap. Spotless computer screens and pristinely clean keyboards have been an obsession of mine since getting my first desktop PC in the mid-’90s. At the time, this was the most significant tech item I had ever received and my most prized possession. Naturally, I was constantly consumed with making it look like it just came out of the box.My knack for wiping screens, dusting keyboards, and removing lint from various connectors grew exponentially over the following years, as touchscreen laptops, big-screen smartphones, and tablets became everyday household objects. And by the time I began testing and photographing tech gadgets for a living, the process of cleaning them had become a legit side gig. In my experience, a good cloth and a brush are essential for reliably cleaning tech and gadgets. That’s why when the Sweep & Swipe laptop cleaner by OXO — a brand synonymous with cheap and clever household products — appeared on my Amazon search feed, I didn’t hesitate to order one. By combining a microfiber pad, a soft brush, and a price tag that’s just a tad north of $10, the minuscule product was just what I was looking for. The accessory’s microfiber pad impressed me by expertly removing smudges and dust specs from the screen of any laptop without the need for a cleaning liquid. All I had to was remove its protective cover and wipe the spot. The Sweep & Swipe was just as effective in cleaning the screens of an iPhone and an iPad, making the devices look as if I had just unboxed them.On the other hand, the retractable soft brush of the OXO cleaning tool came in handy for cleaning keyboards, speaker grilles, and connectivity ports, to name a few essential gadget bits. I particularly liked its adjustable length because it brought even more versatility. I used shorter bristles to swipe between the keys of a MacBook Pro and longer ones to get a mechanical keyboard ready for a clicky work session. The shorter bristles also efficiently removed lint from my iPhone case’s cutouts. And best of all, the brush slider doubles as a proper fidgeting toy with satisfactory clicks.Cleaning the gadget’s brush and microfiber pad was as easy as using them. All it takes is warm water, a bit of soap (for the microfiber pad), a paper towel to dry them, and a few hours to let the excess moisture air out. Weighing well under 2 ounces, the Sweep & Swipe is lightweight and easy to carry. I could throw it in my bag, put it in a jacket pocket, and even fit it in the small pocket of my jeans before heading out to work. It saved me space without skimping on utility. Wrap-Up: I can’t imagine my daily routine without the OXO Sweep & Swipe laptop cleaner. A couple of weeks after ordering my first one, I snagged two additional ones. Now I have one on my office desk, the side table I use as my home workspace, and my backpack.If you are obsessed with mechanical keyboards like I am, consider this just-as-affordable OXO deep-clean set. Its loop brush is particularly impressive, as it can effortlessly clean between keys. This cleaning brush by the same maker is a cheaper and more compact cleaning tool that’s great for harder-to-reach spots.Shop OXO Sweep & Swipe
