The Gonzo Odor eliminator makes use of volcanic minerals to absorb odors. Apparently, volcanic rock is 1500 occasions extra power in absorbing odors than bamboo charcoal. This adsorbent also lasts for up to 2 years and all you must do to take care of its absorptive power is to go away it outside in the solar for 6 hours about every 6-12 months. Once you take the rocks out of the packaging, simply place them in the rooms which are smelling essentially the most and allow them anywhere from 4-8 hours to begin clearing your air successfully.
