Having a clean Xbox One controller is important not only for it to stay looking good but also for it to perform optimally. Dirt and grime easily stick to the controller’s plastic housing. However, you may not know that this debris can also get inside the controller and wreak havoc on its internal components. Fortunately, cleaning your Xbox One controller is easier than you may think.
The worst-case scenario is that liquid has infiltrated the casing. If this happens, you need to move fast to prevent further damage. Otherwise, a dirty controller by itself likely won’t be fatal. Further, dirt can quickly gum up the moving parts, such as the buttons, causing them to stick, which will have a negative impact on your gameplay.
Nobody wants their controller to stop working, so before that happens, here’s how to clean it.
Step 1: Take the Batteries Out

The first thing you need to do is take the batteries out of the Xbox controller. This prevents you from doing any damage to the internal components when using a cleaner. While the batteries are out, you should also inspect the metal contacts to look for signs of rust or debris.
Step 2: Get Supplies

Next, you need to get some supplies. Cleaning electronic components is pretty easy and can be done with household items. The only liquid you should use is isopropyl alcohol because it dries quickly and does not leave any residue. You can use something more powerful on the casing, but spray the cleaner on a rag first, then use the sprayed rag on the controller. It is also a good idea to have a toothbrush and some cotton swabs handy.
Step 3: Clean the Xbox One Controller Casing

Start the cleaning by wiping off any obvious dirt from the casing. While not critical, it will at least make taking the controller apart much easier. Similarly, you shouldn’t worry about the buttons and sticks too much, as you will be able to access them better once you have disassembled the controller.
Step 4: Disassemble

Before you go tearing apart the controller, you should determine whether it really needs to come apart. If any liquid got inside, then it must come apart. However, if one of the buttons is sticking slightly, you may be able to clean the sides of it to get it clean enough. Also, make sure your controller is out of warranty because opening it will void your coverage.
To take the controller apart, you need to pop off the covers on both grips. Then, remove the two Torx screws on each side, followed by the one under the sticker in the battery compartment. Finally, separate the casing and disconnect the ribbon. From there, you can access most of the necessary components for cleaning.
Step 5: Clean the Xbox One Controller Buttons

A common problem is buttons getting liquid on them, which causes them to stick. Carefully clean the sides of the buttons, as well as the button holes in the controller casing. You can use a clean rag, a toothbrush, or a cotton swab.
Step 6: Clean the Xbox One Controller Thumbsticks

The thumbsticks are another common point of failure because they contain complex moving parts. Like the buttons, drinks and other liquids can get on them and cause problems with movements. Be sure to thoroughly clean the entirety of the thumbstick as well as the inner part of the casing near the holes while you have the controller taken apart.
Step 7: Wait Before Using

Lastly, wait a few minutes before reassembling to let the isopropyl alcohol dry. Typically, 5-10 minutes is more than enough before putting the controller back together. Finish up by putting the screws back in and snapping the covers on. Then, all that is left is to replace the batteries and test it out.
Happy gaming!
Stick Drift
Stick drift is an increasingly common phenomenon where the thumbsticks cause the action on the screen to move without the user touching the controls. What this means is that the thumb sticks are beginning to fail. Even worse is that these are not easily replaceable and are considered one of the more complex repair jobs on an Xbox controller.
If your character in a game is moving without you touching any buttons, then you likely have stick drift. Unfortunately, cleaning alone will not work as the problem lies in the sensor. The first thing you should do is contact Microsoft to see if your controller is still under warranty. Then, if you don’t feel comfortable repairing it yourself, look into local repair options or purchase a new controller.
