I take all of the keys off of both desktop and laptop keyboards at least once a year. Just make sure the dogs, cats and/or kids are otherwise occupied, and to remember to turn your head and cover your mouth when you sneeze!
Second, make sure to have an image (photo or otherwise) printed out to make placing the keys back in proper order a bit easier. (I actually keep them all laid out on a cloth in front of me and haven't ever had a mishap requiring the image/map, but it provides some peace of mind)
Carefully pop up a key by prying up on one corner and you won't have any problems with breakage. Just make sure to pay attention when removing and replacing the longer keys, like the spacebar, since there are some added wires to consider. (Having some confidence in one's ability to take things apart and then reassemble them properly, or at the very least having someone with said confidence in the same room, is probably best.)
I remove all of the keys, clean the keyboard base, then clean each key as I'm reassembling the keyboard. I use a combination of canned air and electronics/plastic safe cleaner & disinfectant, some cotton swabs and a soft cloth for wiping down keys and getting into nooks and crannies. While cleaning the keyboard base, I make sure to spray any liquids being used on a cloth or swabs, to avoid having any excess liquid getting into unreachable spots on the keyboard.
It's actually pretty easy to do, and doesn't take more than an hour. I look at this in much the same way I look at car maintenance. A little preventative work can make things work better and help them to last longer.
