CARAVAN Full-Timer's RV Holding Tank Treatment - Probiotic Enzyme Formula - New and Different Enzymatic-Based Approach to Eliminate Toilet Odor (16 Treatments)

This is finally the solution for us to be rid of the smell when we flush! We have tried many kinds of pods and liquids since purchasing our RV at the beginning of this summer (about 3 months ago.)The sensor meter was stuck on full since that time. We have traveled across the country with it, and tried the popular solution of bags of ice with cleaner on board while traveling. Nothing worked to move the stuck sensors for the holding tank. I've tried pods and other liquid solutions, but none of them have worked to eliminate the smell when we flush. We are firm believers in water is your friend when it comes to holding tanks, and sometimes adding the extra water would allow unpleasant smells to rise from the tank as we were flushing. The Caravan solution has enzymes that work exceptionally well to keep the smells at bay - with only using about 2 oz per tank fill!We full-time in our RV, which we have not moved since purchasing this solution, but we are on our second bottle. The cleaning power of it has been shown by the fact that the meter which had been stuck on full for 3 months, has finally moved off of full. This despite many times of emptying of the tank, and use of the water jet cleaner that came with the RVl ! I firmly believe that once we are able to pull the RV out on the road with the tank full and more of the solution on board, our problem of misreading of the meter will be solved. I will update after we travel about 3 hours down the road in November.I would encourage everyone to purchase this product for their RV, whether they are full-timers or not.

Both of my gauges had been stuck on full. I filled the tanks and added the enzymes and let sit for 10 days. It completely cleaned the tanks and got my gauges working again !! The only problem was that it cleaned the gunk out of the valves and they started leaking and had to be replaced. The amazing part was my sewer hose is in a tube and I have to pull out the sewer hose to dump. Normally it is filled with black gunk but after the enzyme, it was clean as a whistle !!

At first use, I didn’t care for this or the tank treatment from the same manufacturer. I went from using a harsh chemical treatment to this. I think the remnants of that chemical in the tank may have affected this product on its first use. Since then, however, that has worked very well. The sensor cleaner works best if left in for several days, but is nearly effective after a day or two. I have only had one odor problem when using this brand (I’ve been using it for three years) and that was in a 100+ heat wave for extended period of time.

We did some research a couple of years ago looking for a holding tank treatment that would actually work. Finding this product on Amazon, liked what we read and decided to give it try.It came in a gallon container, a plus. Easy to use, a plus. Easy to store, a plus. Doesn't leave an over-powering perfume smell, a double plus. Since using, no issues with the tank level reader, a triple plus. Formaldehyde free, which was the biggest plus of all because we didn't want to add to any latent formaldehyde that may be present in our coach.I would recommend this product to any RVer, fulltimer to week-end warrior, luxury coach to any type of RV.

This stuff does not work. I usually use the blue stuff with formaldehyde but tried this to be more eco friendly. It doesn’t work at all. I’ve even tried it at 4-6 time recommended dose. My black tank smells horrible. Time to go back to the blue stuff.

Does work sonewhat but did not control the smell. That is why the 3 star

I was recommended this product by a friend. It is very good. No funny smell in our Motorhome.

My RV. It works!!!
