I love the scroll wheel on top of the Apple mighty mouse, but after a while the sweat and oil on your finger combined with grit and dust clogs the whole thing up. This manifests itself in the scroll wheel not scrolling down, or up, or in worst cases, not scrolling all. Here’s how to fix the problem.

I rang Apple and said my scroll wheel was not working and they gave me this simple but effective solution over the phone.

Simply take a sheet of clean white paper, put it on top of the mouse, and press down on the scroll wheel with your finger, but with the paper between your finger and the scroll wheel. Press quite hard with it and at the same time scroll around – moving it up and down and round and round. Move to a different area of the paper and give it another go.

The paper seems to absorb all the oil and gunk off the scroll wheel, and the scroll wheel in turn when it is clean must absorb the gunk off the sensors or whatever is underneath it.

I have found that a better method, especially with a dirty mouse, is to turn the mouse upside down and run the scroll-wheel in circles on a clean piece of paper until all the dirt comes off.

Make sure you use a brand new clean piece of paper.

Do not use alcohol. The rubber scroll wheel is sensitive and the alcohol is not needed.

No not use water. You don’t want water getting into the inside of your mouse!

It’s just dirty. It’s funny that I could not find this information anywhere on Google or on the Apple web page.

This clean paper trick works amazingly well.

      THANKS !, thought I was up for a new mouse and a long trip to go and get it ! Took 30 seconds to fix using mouse inverted and gently rubbed on sheet of paper, sat the paper on the mouse pad to make sure was a nice flat surface, cheers !

    THANK YOU !!!!!

    Clean paper – invert the mouse – press firmly and roll it around the paper – I saw quite a bit of fluff come out – you will see he webpage go nuts !!!! :)

    Did it a few times now works great again

    In the past with this, I’ve taken the previous mouse apart – cleaned it, but couldn’t get the roller pins back in correctly – it ended in the bin

    Now usually use a BT Magic Mouse with Mac Pro 2008 – had difficulties with BT lagging – just fixed that also:

    Did a SMC reset – power down, unplug the cord, press power button for 5 secs, reassemble and power on
    Also did a PRAM reset

    Then re-paired the BT mouse and all is well

    So with this trick I’ve not got BOTH mice working great

    Thanks again

  7. Carolyn says:

    Thanks!!! Love the internet to quickly solve problems. I thought I would need to buy a new mouse. It would only scroll in one direction. Now – back to new!!

    WOW! This really worked. I was skeptic. IT was too busy to replace the mouse asap so I found this on search and tried it. Rubbing upside down really hard brought out sone yellow gunk and now it works fine.

  9. Angela says:

    OMG, this works! I have 3 more in my desk drawer, getting them out and trying this!

  10. Jenny says:

    I tried paper, wiping the scroll wheel to get the oil off. But it didn’t work. Then I realized I have these oil absorbing sheets (for facial use), and tried that. It worked, so I will keep one sheet just for the scroll wheel.

  11. Bob says:

    Wow. Just wow. It did work :) thanks!

  12. Steve G says:

    Brilliant solution. I have two mice which had this problem, and now they are both working like new – thanks for the advice.

  13. Taruya says:

    WOW, amazing, it works!!!!
    It took me some tries to find out what you’ve meant by upside down… because it looks so weird..
    It’s a shame that it doesn’t appear in Apple site.
