Super concentrate. May be added to cleaning solutions and rinse water or squirt in trash, cigarette urns, etc. RX 60 is a multi-purpose, broad spectrum water soluble counteractant many times the concentration of ordinary deodorizers, thus effective against stronger, more disagreeable odors for longer residual action. RX 60 is formulated with AIRICIDE odor counteractant to change the "geometries" of odorous molecules in the air so they are not perceived as unpleasant. Just squirt RX 60 on the source of foul odors, or add to cleaning solutions, rug shampoo and rinse water, or dilute with water and use as a space spray.
