USB keyboards can be unplugged before you shut down the computer. Doing this with a non-USB keyboard may damage your computer, so if you’re unsure, always shut down the computer first. Take the batteries out of wireless keyboards, especially if you plan on deep cleaning the keys.
Listen for the sound of debris rattling around inside the keyboard. This happens sometimes with mechanical keyboards and other devices with raised keys. Consider taking the keyboard apart to give it a deep cleaning. If you’re cleaning a laptop, hold the screen open while supporting the computer’s base with your other hand. You can also try using a cleaning gel product to remove debris from between keys. These products are a slimy (yet sort of solid) consistency and can be laid across the keyboard and peeled off. When you peel the product off, any loose debris will adhere to the slime. Before investing in a keyboard cleaning gel, be sure to read each product’s reviews so you don’t wind up with a poor product.
To fully clean the keyboard, blow at it from different angles. Face it towards you at first, then rotate it to either side. If you’re cleaning a laptop or membrane keyboard, try holding it as you blow it out. Keep it tilted at about a 75-degree angle so it isn’t completely vertical.
Make sure none of your keys are loose, especially on a laptop. If a key comes off, retrieve it from the vacuum, wash it off, and slide it back into place. Fit it over the key stem or clip to bind it to the keyboard again.
Isopropyl alcohol dries very quickly, so it is a better option than water. You can get it at most drug stores and general stores. Another cleaning option is to wrap a microfiber cloth around a knife. Moisten it with isopropyl alcohol, then push it down into the keyboard’s grooves. This works best for mechanical keyboards with raised keys. Be cautious when working on a laptop. Isopropyl alcohol is still a great cleaning choice, but the laptop’s delicate hardware is right underneath the keyboard. Don’t let moisture drip underneath the keys.
Watch out for frequently used keys like the space bar and enter key. These spots tend to have more grime. You may need to scrub them multiple times to clean them. For very dirty areas, use a toothpick to break through the grime. Hold the toothpick almost flat against the key and rub the grime to loosen it. Scrub the rest off with isopropyl alcohol.
Any isopropyl alcohol on the keyboard dries within about a minute. Water takes longer. If you used water or think moisture got into the keyboard, let it dry out for as long as 24 hours before plugging it back in.
Whatever you do, if your laptop gets wet, do not turn it back on until it is completely dry.
Tilt the keyboard around to help draw out the liquid. If you have a laptop, direct the liquid to the keyboard to keep it away from the motor and other vital parts. Keep the laptop open and upside down, tilting it towards you to force the liquid towards the keys and out.
Paper towels and tissues leave behind debris, so always use a lint-free cloth if possible. During an emergency, you may not have the opportunity to hunt down the correct cloth, so grab the best thing you have available. A dish towel, paper towels, or even an old T-shirt will do.
Most spills dry up within about 24 hours. If you have time to spare, let the keyboard air out for possibly 2 or 3 days.
Unless you spilled plain water, chances are some of the keys will be sticky. Take apart the keyboard to give it a deep cleaning. Consider getting a professional cleaning for an expensive laptop. Laptops are much more delicate and difficult to clean than regular keyboards. A professional can check the internal components of your laptop for damage.
Unplug the power cord if you’re working on a laptop. Touch a key to make sure the computer is completely off. Consider calling a professional to clean the inside of your laptop’s keyboard. A professional technician can take apart your laptop, find damaged parts, and clean electronic components safely.
Take a quick picture of the keyboard with your phone before pulling off the keys. It will help you put the keys back in the correct order later.

If you can’t remove the keys, you usually can remove the faceplate. Take the keys off afterward, if possible, to give the faceplate a more thorough cleaning.

" This may bring up some helpful videos that can walk you through safely unscrewing your laptop to access the keyboard from inside.
If rinsing isn’t enough to clean the keys, try using a liquid dish soap. Fill a bowl with warm water, then mix in 1 US tbsp (15 mL) of dish soap to create soapy water. Denture tablets are also very effective and can be used in place of soap.
If your keyboard is very grimy, soak the faceplate and keys in soapy water for up to 6 hours. Scrub and rinse off everything when you’re done.
Make sure the cloth isn’t dripping or else some of the moisture may reach the electronic components. Use an electronics cleaning brush from a general store to help remove tough debris.
Change out the cotton swabs as they get dirty to avoid leaving any debris behind. Isopropyl alcohol dries quickly, so it’s safer to use than water. Avoid using a lot of it. Dampen each swab lightly.
Make sure the computer parts are in a secure spot so they don’t fall on the floor or get lost. Keep them inaccessible to children or pets so they dry out fully.
If your keyboard doesn’t work, take it apart again. Make sure you assembled it properly and plugged in all of the cables.
