Since Chlorine and ammonia (urine) don't play well together, I seriously doubt there are any tank deodorizers that contain chlorine.
Have you ever read the active ingredients on RV tank deodorizers? Most of them have chlorine or chlorides as an active ingredient. I just looked at a number of them at the store the other day and I couldn't find one that didn't have chlorine or chlorides as an active ingredient. Granted, this store did not have any so-called "natural" tank deodorants.
Take a look at http://www.calarvc.com/pdf/Holding_Tank_Products_as_of_Aug_2010.pdf for a list of active ingredients in many tank deodorants.
My stainless tank was brand spanking new on my last trip. There was serious stink after a few days. This is a combined grey/black tank so there should be plenty of water. I suspect some of the stink was due to the 105 to 110 degree heat. Yes, the tank is vented up through the roof.
