How to Clean Your Keyboard

Spending hours at your computer, whether for work or play, is unavoidable for most of us. Constant use is going to take a toll on your keyboard. Dust and hair buildup is inevitable, and fallen tortilla chips and sandwich crumbs can be avoided only by the kind of discipline many of us do not possess. We’re not here to judge; we’re here to help you clean up. In this guide, we’ll highlight the supplies you might need, and run through how to clean your keyboard step by step.

Keyboard Cleaning Supplies

You can definitely clean your keyboard with stuff you already have in the house, so don’t feel like you have to buy special cleaning supplies. Here are some things you might consider and a few household alternatives you likely have lying around.

Brush: I have had a pop-up brush ($7) for a few years, and it’s perfect for sweeping debris out of your keyboard, but you can use any soft-bristled brush you have at home (a toothbrush or a 1.5-inch paintbrush can work).
Compressed air: A 10-ounce can of Dust-Off ($11) will last you for ages and can be very effective at blasting things loose from your keyboard.
Electric Air Blower: A good alternative to compressed air is a rechargeable electric air blower that you can use again and again. I have the KiCa Jetfan 2 ($99), which has a sliding control for upping the power and blasting everything out and a couple of attachments to concentrate the air. Battery life is surprisingly good and you can recharge via the USB-C port on the bottom. It’s pricey, but I love it. You can use it to blast dust out of anything, from keyboards and PCs to radiators and mesh chairs.
Cloth: You probably have microfiber cloths already, and any cloth will do, but I have found the fancy thin ones you use for glasses work best—pack of microfiber cloths ($10).
Cleaning slime: A tub of cleaning gel ($6) can be effective for removing dust from hard-to-reach places like a keyboard, but I don’t recommend it. Apart from general ickiness, it leaves a residue, gets dirty, and deteriorates quickly, leaving you with a slimy mess that can’t be eco-friendly.
Cotton swabs: You might have Q-Tips already, or you can snag cheap cotton swabs ($3) and use them to clean between keys. Wooden toothpicks work well for caked-on grime.
Isopropyl alcohol: Dampening your cloth or cotton swab with water will usually do the trick, but alcohol is a very effective cleaner. This Max Professional spray ($10) is easy to use.
Magic eraser: For scuff marks and stubborn dirt, magic erasers ($7) made of melamine can be amazingly effective. Sometimes regular pencil erasers can do the trick.
Keycap removal tool: If you’re really going to town and deep cleaning your mechanical keyboard, you may want a keycap removal tool ($6). (This one includes a switch puller and a pair of brushes.)

You probably won’t need most of this stuff unless your keyboard is truly filthy, so try cleaning it with what you have before springing for extras.
