Fixing Dead Keys on a Musical Keyboard

I'm going through the process of me fixing dead keys on an Akai MPK Mini Keyboard. I plan to use this keyboard to help me compose an original intro song for the channel. Here's a quick run down of what I did. -Opened up the keyboard -Clean the PCB contacts for the keys. I used a cotton swab dipped in 90-100% Isopropyl alcohol -Dried out the keyboard -Reassembled it.
