Have you ever blown through the Switch’s cartridge slot? Nintendo recently said on its official Twitter: Stop doing this again.
Ren Tianang wrote on Twitter that if the game card slot of the Nintendo Switch is dusty, do not use blowing or other actions, because when blowing, the droplets may adhere to the contacts, which will cause parts to rust or corrode. If there is dust, it is recommended to use a vacuum cleaner to suck it out.
In addition, Nintendo also stated that do not use cotton swabs to clean the game card slot, because it may also get stuck and damage the contact points that read the game card. Insert the card.
If dust gets inside the game card slot, use a vacuum cleaner to suck it out.

The matter of blowing the cartridges started from the Famicom (FC), and it was a habit that many players had when the console could not read the cartridges. At that time, it was really useful in certain situations, and it became a word of mouth among players. Folklore therapy” did not disappear until the game took CD as a carrier. But later Nintendo publicly clarified that the droplets when blowing air are actually more likely to damage the contacts, which made many players quite surprised that blowing air was the wrong way when they were young.
