Blowing on electronic connectors is a temporary fix with negative long-term ramifications. Your breath contains particles of saliva. That saliva corrodes the contacts worse over time.
Here's the right way to clean a DS cartridge slot (if the damage isn't permanent already):
First, make sure the Nintendo DS is all the way turned off, not just resting in low-power mode. It would be a good idea to discharge the whole battery too. Make sure there's no electric current. This is a precautionary measure to prevent damage to your DS.
Second, Spray electric contact cleaner into the cartridge slot. Wait a few seconds for it to dry, and spray it again. Repeat as necessary. Make sure you hit every single pin in that cartridge slot. Use the included red straw to aim the electric contact cleaner.
Third, use a can of compressed air to blow away any remaining dirt, dust or debris. One again, use the included red straw to aim your blasts.
DON'T OVERLOOK THIS PART!
Finally, use the same method to clean all of your DS cartridges too - even if they already look clean. You can't always see the tiny bits of grime on those little connector pins. There's no point putting a dirty cartridge back into a clean cartridge sot.
Good luck, and happy gaming!
