Nanolex ODEX is a scent-free, fast acting odor eliminator. Nanolex ODEX chemically bonds to unpleasant, odor-intensive organic substances and neutralizes them very quickly instead of just masking them. Tobacco odor, odors from pets, spilled milk, vomit and most other common sources of unpleasant smell are neutralized within minutes. Simply spray Nanolex ODEX directly onto the affected surfaces. Nanolex ODEX is a water based formulation and is thus safe to use on any surface.
