Keyboard typing wrong keys

[pointlesssoul789]

Whenever I try to type the lower case letter U, it comes up with su
I can go back and delete the s, but if I press the left arrow key it comes up with a / aswell as moving back a key
I spilled juice on it yesterday, but nothing happened so I left it alone after wiping it clean

disassemble the keyboard and clean it with alcohol or similar
