The usual stains come from sweat, urine, vomit, food or drinksSometimes they're not visible to the naked eye, but they do leave an olfactory trace; the sooner you act, the better the result.
Humidity is a special case. It can be due to poor ventilation, condensation in insulation or spills that aren't properly dried. Moisture encourages mold and bacteria, which are a source of odor and health risks.

Homemade methods that really work
Sodium bicarbonate: the great neutralizer
