Good budget Keyboard, with cleaning problems

Degree because we have a young daughter who now already happy times sitting with her 5 years at our computers and their children's pages as kika.de or Toggolino visited, there are sometimes on dirt, or overturned glasses and crumbs.
Therefore, we were pleased to find a keyboard that is insensitive to liquids.
It did not take long until the first apple juice found its way onto the keyboard.
Wet wipe was no problem, even the juice caused no loss. Very good!
There's just one small problem: you can not deduct reasonable and certainly not reinsert the key.

In any normal keyboard, you can remove the key, and then remove the collected crumbs or sticky liquids, which have sought their way between the keys.
I had begun to test with a key and they carefully removed. When I wanted to but she reinsert one point of filigree substructure is quickly broken plastic. On the one hand it's a real Fuddelarbeit to put the clip into the grooves while you have to snap the plastic prongs; on the other hand breaks a fast times as a plastic prongs from the button and then hangs crooked and possibly is no longer correct, or only with a lot of pressure.

Quietly, she is definitely, especially if you have become accustomed to having to exert relatively little pressure on the keys. Nevertheless, the keys have a very pleasant pressure point and feel; not spongy.

Those looking for a quiet, beautiful and good keyboard that performs its work in an environment without crumbs and sticky liquids, which should access.
Drivers who have to clean the keyboard and under the keys more often, perhaps you should take a more maintenance-friendly keyboard.

Or someone has a ready disassembly / assembly instructions for the keys of this keyboard?
Would appreciate tips or instructions.
