If your keyboard is part of your laptop, shut down the laptop before you begin cleaning. This will help prevent damage from occurring during the cleaning process. If the keyboard is part of your laptop, unplug the laptop entirely. Otherwise, disconnect the keyboard from your computer, laptop, or tablet. First, carry your keyboard over to a trashcan and tip it upside down. Gently shake and move it side to side to dislodge any loose dirt or objects. Run your hand gently over the keys to loosen dirt that may be stuck. First, turn the keyboard at a 75 degree angle, so it is not quite vertical. Then, spray some compressed air left to right across the surface of the keyboard. Keep the straw of the air compression can about ½ inch away from the keys. After spraying the whole keyboard, rotate it 90 degrees to one side, and spray all keys again from left to right. Repeat this until you have sprayed the keyboard at all angles. Apple doesn't recommend the use of compressed air for all keyboards, as it may push particles further into the the keyboard. This step is specifically for MacBook laptops from early 2015 or later. Get the cloth damp, and then ring out any excess moisture before touching your keyboard with it. Run the cloth gently over the surface of the keys to remove dust and dirt. Be sure that you don't get any excess moisture in between the keys in this process. For stains on your keys or keyboard, use a bit of pressure to scrub them off. Get the cotton swab or cloth slightly damp, and then apply it to the stain. You can rub in a circular motion, gently, until the stain is gone. If you have a white keyboard, take extra time to scrub the dark brown areas that tend to develop on the spacebar and where your fingers rest. Consider using a microfiber cloth for this step. Run it over the keyboard to remove any remaining moisture or dust that may have collected.
