I have a stainless steel black tank. Bleach or anything with chlorine/chlorides will corrode stainless steel.Are there any tank deodorants that don't have bleach or chlorides in them? I'm certainly willing to make my own if I can find a recipe with no chlorides in it. One recipe I looked at used Borateem, bur Borateem has chlorides in it.

Interesting...what RV has a stainless steel black tank? I imagine a tank like that adds lots of weight to the rig.Just interested and always trying to learn. Sorry I can't help you with your actual question.

A bus conversion. A custom stainless tank wasn't much more expensive than a really large plastic tank in the 125 to 150 gallon range. The stainless tank might weigh 40 pounds more than a plastic tank.

Flush your tank out when dumping and you won't need deodorants. Also make sure you have enough water at all times in the tank to keep solids from forming a pyramid on the bottom. I haven't used black tank chemicals yet in my trailer and have zero smell. We try and flush every time we dump and keep plenty of water in it.

Since Chlorine and ammonia (urine) don't play well together, I seriously doubt there are any tank deodorizers that contain chlorine.

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.

Any tank deodorants without chlorine/chlorides?
