I’ve just gone through this interesting exercise with a wired Apple keyboard

First, take a picture of the keyboard so you can refer to it when you’re 
replacing the keys. And also so you can proudly reflect on your cleaning 
prowess. 

The safest thing is to not wipe the keys just yet, simply flick them out one by 
one. Once the first comes out you’ll figure out the right force and angle, but 
a small finger placed under the edge of an exposed key and flicked up to 
release the clip is the best action I can describe. You may need a spodger to 
get the first one, a plastic stick. 

Once all the keys are off, they can be washed in a bowl of cleaning liquid and 
water, rinsed and dried

The exposed base can be wiped clean and the various biscuits you’ll deny ever 
eating, must have been the cat, can be cleaned up. 

Then it’s a matter of clicking the clean dry keys back in place, using the 
photo as a guide. 

I used an overly damp wipe to start with and found excess liquid has seeped 
into the electronic components so the keyboard failed. 

This led me to dismantling it entirely and drying the three layers of printed 
circuit that perform the switching function of the keyboard. There are little 
soft plastic cones that give the soft touch we enjoy. They fall onto the floor 
and hide behind chair legs, so some agility may be required to rescue them. 
Rest assured They don’t fall out unless you dismantle the electronics. Once 
resembled twice, I first put the cones in the wrong way, my keyboard is clean 
and functional and has passed the most stringent assessment of my wife. 

I hope this helps
