For some history, let's remember the words of an internationally recognized expert. There are 3 basic methods of eliminating undesirable odors: concealing them with stronger scents, like the ubiquitous lemon and pine fragrances chemically flaking or absorbing them, as with activated charcoal or vera gel and numbing your nose out, so that you can not smell something. To be precise, not long after air fresheners had moved on from using formaldehyde as a nasal anesthetic. Alright, so obviously Febreze can not make odor evaporate. Odor is not some intangible thing -- smells are caused by molecules that evaporate into the air and activate receptors inside our noses, signaling that the presence of a specific chemical cocktail to our brains.
Meanwhile, perfumes added to the Febreze mix -- presumably ones who are hydrophilic instead of hydrophobic, restricting their tendency to end up stuck in cyclodextrin rings -- further mask these now neutralized scents.
While some forms of odor removal may be done by a homeowner with no technical experience, professionals will be necessary for more stubborn, unpleasant scents. Their advanced skills allow them to eliminate smells due to fire, smoke, mold, and thorough pet soiling. While homeowners have some tools available to help control these issues, professional assistance is usually required to remove them completely.
