    One of the keys to making an RV trip as enjoyable as possible is making sure everything is running smoothly. Nothing can ruin a trip like having to deal with toilet odors or, worse, clogs and backups in your holding tank. You need something that is going to do that work for you, so you can focus more on what you got the RV for in the first place, relaxation, exploration, and travel with family and friends.

    Unique RV Digest-It’s powerful probiotic blend goes to work, quickly digesting solid waste and residual sludge build-up inside your holding tanks, preventing backups and clogs from happening in the first place. It’s advanced blend of bacteria and enzymes work quickly to remove the odor-creating pathogens from your holding tanks, replacing them with odorless aerobic bacteria, so your holding tanks can remain odor free.

    RV Digest-It provides you with multiple application options, many costing you less than $1 per dump - Liquid, Drop-In Pods, and Scoopable Powder.

    Thousands of RV Users Already Trust RV Digest-It To Clean And Deodorize Their Holding Tanks.

    Unique RV Digest-It uses a highly effective blend of bacteria and enzymes that go to work quickly, ensuring that your holding tanks remain clog and odor free. Bacteria needs a food source to survive, and the waste in your holding tanks are the perfect food source for the bacteria. Once the bacteria encounters a food source (the waste and odors in your holding tank), it becomes active and begins to eat. As the bacteria eat, they produce enzymes. These enzymes help to break the waste down into more easily digestible portions for the bacteria so they can completely eat and digest the waste, leaving behind nothing but carbon dioxide and water. The bacteria in RV Digest-It is also specially formulated to force out the bad, odor-creating bacteria (anaerobic) and replace it with good bacteria (aerobic) so sewer odors are eliminated at their source without using any dangerous chemicals, masking agents, or strong fragrances.

So far great stuff

I am new to this RV Digest-It liquid treatment. For the past 20+ years, I have used what the toilet manufacturer suggested. I am on my second 32 oz. bottle and am impressed. It took a few times emptying and flushing the tank to get rid of the old chemicals so that the bacteria could do its job. It didn't make the sensors work again but, they didn't work when I bought the RV. I am impressed with the lack of odor and I am sure that the owner of the park where I am now staying appreciates me not using a chemical-based product.

Unique Camping + Marine

RV Digest It Powder

Two years ago, I started using RV Digest It liquid and am very happy with the product. When the powder became available, I tried it and it is as effective as the liquid but the container that the powder form is in weighs less than and takes up less storage space than the liquid.

Best product for full timers!!

I live in an RV year round with my family. This is the best black tank product on the market. It cleared the sensors when we traveled too. And, yes, it really only needs 2oz per use. Keeps odors away even in hot climate. Never buying anything else!!

Unique Camping + Marine

Wow, Kate, that is high praise indeed! When our products work so well for full-timers, you know they are top-notch. Thanks for your purchase and for your 5-star review; we appreciate it! Stay safe out there!

RV Digest-It Holding Tank Treatment Liquid

We have used Digest-It in our Airstream for more than 10 years. Works great. We never have any problems with odor or clogging in the tanks. Also use the Digest-It when cleaning the toilet bowl, which avoids adding harsh detergents to the black tank. We often need to order directly from you on-line because we can't find it locally.

Unique Camping + Marine

Thanks for you 5-star review, and for being faithful customers for so long. We're always happy to have you buy directly from us, but you'll be glad to know that we are in over 1200 stores throughout the US. So chances are good that wherever you go, you will be able to find RV Digest-It in the area. Happy and safe travels!
