The day that my girlfriend got me a Razer Onza controller was like the best day ever, it was so sexy until it started to fail, then i was like WTF… Razer isn’t supposed to fail at two weeks from purchase, the left stick became less sensitive, followed by left trigger, so i turned for some good ol’ google search, turns out that it’s so common for it to break really soon, but my curse was that i live in Mexico, so no warranty for me, so i started the “Let’s fix this thing” quest.
Since i had this cool canister of silicon oil (used to clean potentiometers without damaging any plastic) laying arround i cracked open the controller case, and sprayed a little bit of oil on the trigger and stick pots, the trick worked but only a few weeks, then i became sad… what other thing i could use to fix this great controller.
This was the point when i tried WD40, it’s like canned sweat from gods, it’s been more than 2 months without any simple fail, controller is working just as it was on the 1st day, if you have a Razer Onza laying arround just remove the rubber caps with a toothpick, then a phillips screwdriver for removing the screws.
Some WD40 on every potentiometer (orange little things inside the controller) there are 6 of em, 2 on each stick and 1 on each trigger.
You can soak them wet, then clean the excess with a paper towel, since WD40 it’s dielectric it won’t cause any harm to the electronics inside of it.
Hope this works as good as it did for me.
