Solved mouse wheel orientation turned 180° after Sprayed with WD40

December 25, 2015 at 17:37:05
Specs: Linux x86_64)
I sprayed wd 40 into my wireless mouse and left became right and up became down. Sometimes it acts normal but mostly it is as if the mouse wheel has been turned 180 degrees (it is also hyper sensitive). Any idea how to fix it. It has been going on for 11 hours now (ample time for it to have dried). Any idea how to fix it? I did it because I think I had corrosion on the terminals and I was cleaning them. I realize now that I should have dabbed the terminals. oops

Maybe it will dry out further in time. As you say, mat might help too.

Use Ethyl Alcohol or contact cleaner to get the grease of the laser lens.
If you have problems with dirty contacts use the Contact Cleaner.

"ample time for it to have dried"

Among other things, WD40 is a lubricant. I don't know why you felt is was something to use on a wireless mouse, but you will now have to clean off all the oily residue. You may have to buy a new mouse.

WD-40 is a petroleum based product. Oil doesn't dry, depending on it's viscosity it can take months to years to evaporate.

"I realize now that I should have dabbed the terminals."
The wheel is optical using infrared sensors and the buttons are sealed micro switches. There is nothing that would have been fixed by spraying WD-40 inside a mouse would have fixed. You might try opening it up and see if the WD-40 can be cleaned off the sensors and wheel.

yes, there is no actual wheel as it is an optical mouse. What I meant by saying the wheel has been turned 180 degrees is that up is down and that left is right. I'll go to lowes today and get some wd-40 cleaner. Thanks for the suggestion. We'll see what that does.

I remember long ago my dad had this stuff that I would spray onto oily stuff that would absolutely strip the oily stuff and clean it. Any ideas as to what does that? I thought it was wd-40 but I guess I was wrong.

You don't spray "stuff" into things to fix faults. You either replace the item or, if you are experienced enough, disassemble the item, find the reason for the fault and then fix it. Sounds like you've been watching too many soaps.

You can spray stuff on electronics in hopes that it will work but not WD40 but alcohol. Indeed WD40 dissolves some oils and lubricants even makes grease to be cleaned out easier but on cars and bikes not on electronics. Now you take that mouse and bathe it in alcool(Isopropyl or ethyl) take a clean brush and clean it properly until there is no WD40 left at at and by bathe i mean submerge it completely leave it several minutes and then maybe you will salvage it. As it is said above WD40 takes a long time to dry and even if it dries leaves residue behind.

There's nothing to stop anyone hoping whatever they like I guess. If this is some new religion then I've missed out on it.

bmike 1 said in the original post that he used WD40 because he thought
there was "corrosion on the terminals" and he was cleaning them. There is
nothing obviously wrong with that. I wonder what "terminals" those could be,
though. And I wonder why he thought they were corroded.

A problem I sometimes have is friction between plastic parts. I doubt that
WD40 is appropriate for that, but it is something I might try if WD40 was the
only lubricant at hand.

The problem of a backward mouse is one I've seen asked about before, but
I can't imagine how it could result from monkeying with the hardware.

A mixture of WD40 and dust can cause unwanted electrical conduction on the circuit board, which could result in any old symptoms. "Squirting" WD40 into a mouse means it could go about anywhere. It is not a controlled method of dealing with a delicate thing like a mouse - far more suitable for easing rusty bolts. To have a chance of repairing a mouse requires care and thought.

The easiest way to prove/disprove whether the mouse itself is faulty or not is to try another one.

okay.... the final thing I did was followed the suggestion of soaking the mouse in rubbing alcohol and to clean the board. I took the mouse apart and soaked it for like ten minutes. I then took an old toothbrush and lightly wiped anything I could access. I then put it back together and let it sit. It is slowly becoming functional again. If, in two days, it is NOT back to normal I will take it apart again and then remove the board so I can access the underside of it. I didn't do that the first time because it entails removing a cable that I fear I won't be able to reattach without breaking something. It seems very delicate.

I am considering locating wd-40 contact cleaner as sluc suggested and trying that before I take that board apart. Anyone know where I can get that in the USA? Supposedly walmart carries it but Lowes is supposed to carry it as well but doesn't.

EDITED because post #10 wasn't there when I first replied.

Wouldn't it be better to just buy a replacement mouse? The corded optical ones are inexpensive.

Also, what was the original fault you were trying to fix with WD40? Quite possibly that fault will still be present.

yeah... it works fine. I bought one at goowill for like $2. I know it would be easier to just buy a new one but I am extremely poor (on ssdi) and I need to do something to entertain myself!

The original fault is that the battery contacts had a little corrosion on them (I think). it was not working periodically.

OK, well now you've looked inside you will understand that the way around the presence of WD 40 is to clean the board with cleaning fluid. Maybe you can get to the underside with a cotton bud. It is still possible that the original fault will be there.

If you have to buy cleaning fluid it could cost nearly the same as a replacement corded mouse.

Re your #17. It sounds like all you really know then is that the left right buttons (presumably) were playing up. Corrosion is unlikely inside a mouse unless it has become wet at some time. Much more likely is contact wear or some other defect inside the micro-switches. The contacts were probably not closing sufficiently.

When you've cured your WD40 trouble, if necessary perhaps you can get a touch of cleaning fluid to run into the switches. You could drop it on using a very small screwdriver. You might be lucky I suppose. Sometimes giving faulty switches a series of firm taps can get them going, at least for a while.

EDIT:
The irony is that if you had used some implement to apply the WD40 so that it ran into the micro-switches it "might" have helped, although cleaning fluid would have been a more suitable option. The mistake was getting it all over the place and not focussing on where the actual trouble was. That approach just added an extra fault.

Yeah.... realized that I should have just dabbed it after I did it. I dabbed it on the termonals of the keyboard (which was doing the same thing) and it works great now.

Battery terminals seem to corrode in lots of situations even without water.
I suspect that it is a galvanic effect involving different metals in contact.
But a mouse has a great source of water all around it: perspiration from
the hand.

Using WD40 on the battery terminals makes sense, but not by spraying it
and getting it on everything.

Derek,

It doesn't appear that he had any problem with the buttons. The problem
is that the directions reversed. Move the mouse forward and the pointer
goes down. Move the mouse left and the pointer goes right. I've heard of
that before but I can't imagine how it happens.

now everything moves correctly though it does not move as fast as it should and it wobbles to the sides of the direction you are moving the pointer.

okay, now the mouse is acting normal when I use it against my leg but it moves slow and jaggedly when I use it on my desk or a piece of paper or on a book or a folder. How strange and stranger still. I suppose I'll get a mouse pad?
