One of the biggest bits of Nintendo lore comes from the NES days, back when kids were blowing into their NES cartridges to get them to work? Did that actually bring your NES games back to life? Nintendo would say no, but millions of children would argue otherwise!

Decades later, Nintendo is still warning against spitting your hot breath at their products. In a recent tweet from Nintendo, the company has told Switch owners that they should hold off on blowing into the Switch game card slot to clean things out. As you might guess, there’s a much better and safer way to clean out the card slot.

Inside of game card slots, there are contactors that read the game cards. If you try to clean this area with a cotton swab or insert a damaged game card, you could possibly damage the card reader. Please do not touch the inside of the game card slot.

If dust gets into the game card slot, use a vacuum cleaner to clean it. Do not breathe into it or similar. Saliva may adhere to the contactors and cause rust or corrosion.


Sure, it might be a lot easier to blow into your Switch to clean out the card slot, but you’re risking some serious damage by doing so. Next time, grab the right tools to get the job done in a safe way.
