TrackPad Gone Crazy After Cleaning (Wet Cloth)

I cleaned my Macbook Pro 15 Unibody by wiping it with Radtech OmniCleanz spray while the mac is On,three days ago,and since then the mouse pointer gone crazy :

- Randomly moving and applying clicks & gestures without touching it.

and when i try to touch it and try to move the pointer it gets worse.

In order to get control over the mouse i connected external mouse and disabled the trackpad.

I tried : restarts\ shutdown down and power on with Option+Command+Power Button

I cleaned my mac hundreds of time the same way and never had any problems , except for one problem simliar to the current one, and it got fixed by its own few hours later.


It got fixed by it self , I think the problem was related to calibration or something like that.

thank u anyway :)

Answer this question I have this problem too

Is this a good question?

Did you sprayed it directly on the mac ? Anyway, never clean your mac or any electronic device with something humid while turned on, this is what happen if you do so.

Some liquid has probably infiltrated by the side of the trackpad and short circuits the electrodes under it.

I don't know if it can be repaired, probably. But what you can do until someone else answers, is to open it up, take off the battery, disconnect the trackpad and try to unscrew it to see if there is still water.

I found this guide but it's for macbook 13"

I would make an appointment at an Apple store to see a "Genius" if I were you...I definitely don't think you should try to disconnect the trackpad yourself if you don't know what you're doing. People online make it sound like its easy to do, but you can really make things worse tweaking around with it. Believe me. The people at the Genius Bar usually hook you up, at the very least they can tell you how much replacement parts will be...
