My apple wireless keyboard got wet a year ago i sprayed the cleaning spray on it some of the keys are working but some of the keys aren"t working. it got sprayed a year ago What should i do??? Can it be recovered plz tell?

There is almost no chance it can be recovered, except at a cost far greater than a new keyboard. Once wet, spraying with a cleaner will not do any good and most likely will make the situation worse.

Best thing at this point is go to your Apple store, or the on-line store, and buy a new keyboard. Water damage is not covered by the warranty or AppleCare.

taken many keyboards apart and cleaning the membrane of coffee/soda/wine/beer and the likes

few if any ever ended up with all keys working if I were you I would flush it down the toilet and buy new one
