Question I spilled a tiny milk drop on my mouse wheel by accident and now it won't work

[TheManyzzz]

So the other day I accidently spilled a bit of milk on my mouse (don't ask me how I'm just dumb by nature) and everything works fine except the mouse wheel that scrolls up and down normally on the mouse itself but doesn't work at all on my pc! If you had a similar problem or know how to solve it please help me because it's really weird that the wheel scrolls normally but doesn't work at all on my system.

test with another mouse?

I didn't do it yet because I couldn't find any other mouse but I did test it on my second pc and it also didn't work there

try cleaning it or replace it

What mouse is this? Before any attempt to disassemble the mouse, be aware that some of Logitech models have a mechanism that is set up so when the wheel are removed, the spring (that cause mouse weel to rotate in small steps) have a tendency of flying away (I've lost a couple of springs this way) - so make sure the springs cannot fly/jump far away.

Now, if you insist on try to clean it yourself, know this:

• Under the cover, the mouse wheel consists of thin spokes, having a infra red transceiver and sender on each side.
• Those are the sensors that detect the scrolling.
• If you spill milk or other liquid substances on the mouse, it's a good chance that it get between the mouse wheel spokes and on the infra red censor itself. Those are the parts that you have to flush/clean.
• However, just flush it with water without disassembling will probably not help.
• Before assembling it back again, make it dry first.

It is a Logitech G502, I've never disassembled any moused and certainly don't have the tools for that so I might think about buying a new one or send it to a shop that does that. Still thank you very much for the info, I couldn't find any info as helpful as yours on the matter so again thanks alot!

My question: which model G502?

I found 4 (four) models. The shop may charge you more than it would cost to buy a new G 502 mouse of the same model.

G 502 models: Hero, Lightspeed, Proteus, Proteus Core.

Per @Grobe:

"However, just flush it with water without disassembling will probably not help ".

Agree. However my view is that there is probably little to lose by trying.

Flush the unplugged mouse with distilled water, shake out, and flush/shake again. Do not overdo the shaking part.....

Place mouse in a warm dry ventilated place and let thoroughly dry as recommended. Position so any remaining water could drain out/away from the scroll wheel.

My belief is that the repair shop is likely to try that (or something similar) as a first step anyway. Maybe put the mouse in a bag of rice.

Safer for them, in some ways, than risking a runaway spring.

(Scenrio: They lose a spring, give back the mouse, say the mouse cannot be fixed - then bill you.)

Just my thoughts on the matter.
