My keyboard isn't working properly

When I was cleaning my display, I spilled a little bid of the cleaner on my keyboard. Only a few drops. Later I noticed it my keyboard was freaking out and all the keys I pressed would input symbols. I turned my computer off and let it chill for a bit and then my keyboard didn’t work at all apart from the power button. I tried the P ram reset, didn’t work, I reinstalled OS X and the keyboard worked again except when I press 1 - 9 or q - o it double presses. For example q inputs q1 or 1 inputs q1, w inputs w2 and 2 inputs w2. Does this mean it’s a hardware failure and I need to replace my keyboard?
