i spilled a sweet drink on my keyboard [duplicate]

Right now I’m using on-screen keyboard. Yesterday I spilled a sweet drink onto my keyboard so I cleaned up the liquid that didn’t go in the keyboard with a damp towel. I thought I fixed it so I continued what I was doing. The next day, I couldn’t type anything. if I typed the letter “s” it would come as “[/s” what do i do now? I tried searching it up what to do, but all of them are about as soon as it happened. I found one that told me to shake it, but nothing came out. The keyboard is a logitech K360.
