When cleaning the room alone doesn’t eliminate stale or bad odors, deodorants may be used to counteract and chemically absorb the molecules responsible. Liquid sprays, powders, or heat activated capsules neutralize stenches while injecting more pleasant scents into the air. Covering the smells generated in the laboratory with natural or fruit fragrances, work spaces become more enjoyable for personnel. By improving the overall air quality, deodorants complete the final step in making rooms fresh.
