How to Clean the Nintendo Switch Card Reader


“The game card could not be read. Please remove and reinsert it.”

“There is nothing inserted in the game card slot.”

If you’re seeing the above game card reading errors on the screen of your Nintendo Switch it could be because your console’s card reader is dirty.

Recently, on more than three occasions I got these messages while trying to load Monster Hunter Rise and Super Mario Odyssey game cartridges on my Switch.

Only on the second or third attempt was the Nintendo Switch card reader able to load the games.

I did some research online and found that cleaning the Nintendo Switch card reader could make these random card reading errors go away.

I cleaned my Nintendo Switch card reader, and now all game cartridges I have loaded on the first attempt.

If you’ve found yourself in a situation where your Nintendo Switch card reader isn’t working as it should, it might be time to clean it.

While the Switch game card slot is covered and rarely needs cleaning, it is possible for some dirt could collect in it, compromising how the card reader connects to cartridges inserted into it.

So, how do you clean the Nintendo Switch card reader? To clean your Nintendo Switch card reader you’ll need Q-Tips or cotton swabs and a 70% Isopropyl alcohol cleaning solution. You’ll use these two items to remove any dust or debris which may have worked its way inside the Switch card reader. While it is common to use compressed air to remove dirt in electronics, I don’t recommend you use it to clean your Switch card reader. The condensation caused when you spray compressed air into the card reader could damage the Nintendo Switch card reader.

What to do if your Nintendo Switch card reader isn’t loading Nintendo Switch game cartridges

Use a flashlight, or torch if your from the UK, to look into the Switch game card reader slot.

Several reasons could cause your Nintendo Switch card reader to have trouble reading a game cartridge.

So, before you proceed to clean your Nintendo Switch card reader I recommend that you do some troubleshooting. 

Here are a few tips to help you troubleshoot a Nintendo Switch game card slot that is not working properly:

  • Take a flashlight or bring your console under a bright light to inspect the card reader slot. You’ll be checking to see if the metal points inside are bent, broken, dirty, or have any issues.
  • An old systems software could prevent games from loading as they should. Therefore, confirm if your Nintendo Switch has the latest system update. You can do this by going to System Settings from the Switch’s Home Menu, then select System, and System Update. If a new software version is available the console will begin to download it immediately. Once the download is complete try loading your game cartridge again to see if it will run.
  • Check for software updates for the game refusing to load by going to System Settings, >System>Auto-Update Software.
  • At times a bug could be the reason why your Nintendo Switch game card reader isn’t working well. You can fix this by: powering off your console. Then remove the Nintendo Switch cartridge from inside the card reader slot before putting it back in and turning on the Switch. 
  • Confirm that the game cartridge you have is compatible with the Nintendo Switch and if it is an original cartridge. Fake Nintendo Switch cartridges might not be read by your Nintendo Switch card reader.

If after troubleshooting everything looks OK you can try cleaning your Nintendo Switch card reader slot to see if it will sort out the game card reading issues.
