Up arrow key not working after cleaning
I have this Apple Aluminium Keyboard A1243. Some days ago i saw that these white keys are looking very pale. So i used a shiner / cleaner liquid, sprayed on the keyboard and cleaned it with the cloth.
The keyboard looked very clean but then many keys stopped working. So i unplugged it and placed it at side for drying and started to use a Dell keyboard. After some hours only "K" and "Up arrow" keys were not working. Then next day i plugged it in and it was like K is being pressed and in any text area "kkkkkkkk...." would appear and after sometime it started to work normally.
But its been a week now almost and the UP Arrow key doesnt works. i have tried to remove the key and checked beneath there, nothing unusual there.
