Same here, except lemonade.

Easy to fix though, get some tiny screwdirivers.. this video shows you what 6 screws to undo:

The start of the video shows you how to take the 2 halves apart, once you've done that clean all the guides and exposed sliding parts with some isopropyl alcohol or wet earbuds or cotton or similar.. reassemble and it will be as good as new, mine is..

Good luck!
