For any realtors or homeowners dealing with the odor problem I have found the miracle solution.  I am the property manager to a large apartment community.  At the beginning of every month I deal with odor problems from recently vacated apartments.  Some are more severe than others. Last month we had a really severe smelling apartment.  Even after fresh paint and new carpet we couldn't get cat urine smell out.  One of my maintenance guys brought me a product called Room Shocker this product works like no other product have ever tried.  It's simple to use and not labor or time intensive.  So there's no scrubbing or spring or wiping.  It's relatively inexpensive.  It's not a masking agent and gets rid of the odor at the source.  It not only gets rid of the smell, but it completely Decontaminates and disinfects the whole room.  So far I've been able to get rid of severe pet odor, the smell of cat urine, heavy cigarette smoke odor.   I had trouble finding the product but I found it on a website called BiocideSystems.com.  I guess it's fairly new.  I swear by this stuff now and then highly recommend it to realtors and  Or apartment managers and owners. The stuff really works!
