Option #1: Using PaperMaterials:
- A clean Sheet of Paper
1. Create the Cleaning Surface After unplugging your mouse or removing the batteries (just in case), place the sheet of paper on a cushioned surface (such as a book).
2. Clean the Ball Hold your mouse upside down and drag the ball with slight pressure (still letting it rotate) across the paper. You'll see the gunk come off as you do this. Once residue ceases to come off the ball, it should work better.
Additional notes: This removes some grit and grime, but in my experience the roller ball still does not function at 100%.
Option #2: Using TapeMaterials:
- High quality Scotch Tape
- Utility knife or scissors
1. Cut the Tape Cut a 3" piece of clear scotch tape to about 1/8" in width with a utility knife.
2. Feed the Tape After unplugging your mouse and removing the batteries (just in case), begin to feed the tape (sticky side up) below the ball. This is tricky, but once the tape grabs hold of the ball all you need to do is apply slight pressure while rolling the ball away from the tape so that it takes. Using pressure and patience, eventually the tape will emerge from the other side. Use your finger nail or utility knife to unstick the tape from the ball so you can feed it all the way through.
3. Buff the Ball Gently tug the tape back and fourth, buffing the underside of the ball. Repeat until the ball is clean all the way around.
Additional notes: This is a satisfying and effective cleaning method. Source: Brendanfenn
