I strongly dislike dirty keyboards, especially if the dirt does not come from me. I also read a newspaper article which claimed that some studies proved that many keyboards are more contamined biologically than the average toilet. Now, I always did take apart the keyboard, put everything (except the electronics and the contact foil) ie. keys, springs etc. in hot water with dish washing products. After an hour I cleaned the parts with clean water from the dish washing products. Then I let the parts dry from a whole day and put everything together again. It all takes a lot of time. I only did it because I needed and wanted this keyboard. I would never have done it for a normal PC keyboard (which I simply would have replaced by a new one). The results are very good. The keyboards now all looked like new ones. I think that if you really want to remove all the hair, food rests from other people you will have to take it all apart! It is not possible otherwise.
