How to fix 3DS cartridge not reading?

To fix a 3DS game card that won't read, start by powering off the console, removing the card, and reinserting it firmly; if that fails, gently clean the gold contacts on the cartridge and the pins in the console's slot with 91%+ isopropyl alcohol and a cotton swab or folded paper, then try reinserting a few times, as dust or minor grime is the most common culprit. If it still won't work, check for bent pins in the slot using a bright light and a dental pick, and if all else fails, try deleting any update data for that game and redownloading it from the eShop.

Should I use 70% or 91% isopropyl alcohol?

For general disinfection, 70% isopropyl alcohol is better because the water helps it penetrate and kill germs effectively by slowing evaporation; 91% is better for cleaning electronics or removing adhesives, where faster drying is needed but disinfection isn't the primary goal. The water in 70% IPA acts as a catalyst, denaturing proteins and destroying the germ's cell membrane, while 91% can coagulate proteins too quickly, frying the outside without fully killing the microbe.

If you must, use a very diluted mixture (like 50/50 with water) applied to a microfiber cloth, never directly on the screen, and only if manufacturer guidelines allow for tough spots; otherwise, stick to plain water or specific electronics cleaners.
