I spilled tea on my magic keyboard

I spilled tea on my magic keyboard. I mopped up the spill and continued using until I noticed the keyboard acting funny. Then I remembered I was supposed to make sure I had drained out any remaining tea in the keyboard. I was working and I did not have another keyboard so after I felt all tea had been removed after shaking it out and mopping up again and again with tissue I continued using it. However, I noticed the E and R keys were no longer working...

What do I do?

Thank you.
