Step 1:
Stick your fingernail in the top part of the outer ring.
Step 2:
Pry the ring out lightly with your finger nail.
Step 3:
Pry out the 2nd ring VERY lightly, as the 2nd ring is very thin and easy to bend.
Step 4:
Take out the base of the trackball, again by prying it out with your finger nail.
Step 5:
Use rubbing alcohol and a Q-Tip and DON'T soak the Q-Tip with the alcohol, jut have a little bit on the swab and let the cotton swab roll around the trackball to remove any excess dirt and make ur ball cleaner ! Then use the opposite side to dry it of course....
Step 6:
Do the same thing you did when you took it apart, and you may want to use a lead pencil to get the 2nd ring into its place because there is a small slot to get it in... If you want pictures on how to get the trackball together, just ask !!
