The specs of saliva that go along with blowing corrode the contacts over time, so it is actually better to find an alternative with a soft brush and non/less-acidic cleaning solution.
Nintendo sold cartridge cleaning kits in the 90s (maybe even the 80s).

No one bought those. By the time any corrosion occured, you mastered the game.
