A cleanable computer keyboard

Look at your keyboard and you know what I mean.

Why is there still no cleanable keyboard around?  That is nice to use at the same time I mean.

Some ten years ago I tried cleaning a keyboard thoroughly.  I popped 10 keys a day loose and cleaned.  After two weeks I was finished and the keyboard was only a tad cleaner.

Dishwasher cleanable, only the keys or preferably the whole keyboard.  Or washing machine washable even.
