        I, of course, was skeptical. I've used nothing but deodorants since I started boating in my 55 ft houseboat. I thought I'd give this stuff a try, since it seemed to make sense, what with the oxidation to nitrogen and all. In fact, and much to my pleasure, it worked as advertised. My blackwater vent is on the starboard side, and , used to be, no one wanted to sit on that side if I had not recently pumped. Now there are no comments like OK, who flushed...?" I found myself a little behind the "odor ball" when a bunch of folks showed up for a long weekend, and it was HOT. As you all probanly know, heat only makes things worse. The tank was 3/4 full, and had been collecting for 2 weeks, and the day we came in, we could all detect just a bit of stink. Next ime, when I see all those folks pulling up, I'll add another shot of Odorless..."

        We have used Odorlos liquid for 20 months to treat two (2) 45-gallon blackwater holding tanks in constant use. The tanks are well ventilated. The attached toilets use fresh water to flush. In those 18 months, Odorlos has NEVER suppressed the odors, and the natural bacteria in the sewage has NOT SUCCEEDED in digesting the solids. At every bi-weekly pumpout, the treated sewage appears and smells completely untreated. We have given up on this product, and are switching to Bactain, a bioactive treatment.

        Dry powder form liquifies

        By Rabid Sailor

        About Me Advanced

        Pros

          Cons

            Best Uses

              The packaging of the powder form is not suitable for the marine environment. The packets are not air tight and the contents liquified in the high humidity marine environment. The resulting liquid leaked out of the packets and damaged the wood finish of the cabinet they were stored in.

              Comments about Odorlos Head Chemical, 4oz., 10-pack:

              After each black tank dumping, I add Ordorles to the tank as I add water( 25% full). One if my RVs is a cabin at lake & never moves. In a 4.5 month season I dump only 3 times. Even in hot, humid weather we have no sewer smells.

                Comments about Odorlos Head Chemical, 68oz. Bottle:

                We were staying at an RV park for a few weeks bring stationary, and we started to have awful smells coming from our black water holding tank. The main reason, we believe, was because the park was on well water, as well as the fact that we were stationary for much longer than usual. We used Odorlos and we have immediately had a difference in the smells. They were gone within a day or so after using the Odorlos. We definitely recommend it if you start having any smells or an increase in bacteria growth in your tanks.

                Service and delivery comments:

                West Marine shipped this item out quickly, and we also had free shipping, which was great!

                Odorless is the best we have found for our house boat. The container makes it easy to add to our tank and the solution does not leave an unpleasant odor even in the heat of the summer

                    We have tried various products, but this one is the best. There is a smell only on the first flushing; after that, no smell all weekend. Recommend new package added for every 3 days of usage.

                        Been using Odorlos exclusively since installing a new tank 4 years ago. Directions say to start with clean tank, so I figured great time to try this product. Head gets used every weekend and 3 full weeks every summer. No odors in boat like before. Got news for an earlier reviewer, everyones stuff stinks when pumping out. It is sewage after all. The important point is it doesnt smell in the boat. Pump out about every 3 weeks.

                        works as advertized, no smell. I have used this product for 4 plus years with no problems.
                        The holding tank must be well vented so if you have an ugly smell make sure your vent line is not plugged.

                              In our boat and motorhome heads, we use the granulated version of Odorlos, which comes in a box of 10 sealed envelopes of 4 oz. each. Nothing to measure or splash. No large bottle to lug around. NEVER any odor!

                              We have used other "brand name" toilet chemicals, (liquid and granulated) but always ended up feeling like we needed to dump prematurely due to the odor build-up. Will continue to buy and recommend this product!

                              After about 6 pumpouts I gave up, and went back to a formaldehyde product. Based on other reviews, maybe I am doing something wrong, or it is not suited to my equipment, but I have a half a box to give away, if anybody wants it.
