Keyboard mushy after disassembly

So, about a month ago, I spilled about 1/5th of a glass of water on my Logitech K120 keyboard. I immediately disassembled it and removed any water that was in there. After I reassembled it, every key worked flawlessly but it felt really mushy. The keys didn’t spring back up after a keypress. So I got a new one and I was wondering if I could fix it to use it with my also water damaged late 2007 Macbook. Does anyone have any suggestions? (Sorry for my bad english)
