Keep your RV black tank clean and odor-free the easy way. Unique RV Digest-It Max Concentrate Stick Packs are a newly formulated RV toilet treatment designed to break down waste and all brands of toilet paper faster than ever before. Reliable and effective, this RV black tank treatment helps prevent clogs, unpleasant odors, and misreading sensors in a convenient, grab-and-go format.
RV Digest-It Max Stick Packs feature our classic bio-enzymatic RV tank treatment formula that liquefies human waste and toilet paper without masking odors with fragrances and perfumes. Instead, RV Digest-It Max Stick Packs tackle odors at the source, acting as an RV tank deodorizer. This RV holding tank treatment is safe to use in your RV, and won’t cause damage to valves, seals, and other holding tank components that can be damaged by other RV toilet chemicals.
Instead of figuring out where to store jugs of camper toilet treatments and RV maintenance supplies, these space-saving, pre-measured RV Digest-It Max Stick Packs make RV holding tank treatments simple and easy. Other black water tank treatments rely on RV toilet pods that can easily break or don’t fully dissolve, but RV Digest-It Max Stick Packs feature a no-mess design that easily dissolves in your RV toilet bowl every single time.
With improved odor-counteracting capabilities, say goodbye to stinky tank odors even in hot weather.
Liquifies solid waste and all brands of toilet paper quickly to prevent waste and sludge buildup in your tank.

"This is the only product I use. I live in my 5th wheel and it was a 2007 when I bought it in 2024. So the tank was not great. Using this product and all of the tank products, my tanks are like new. I don’t use anything else."
"This is our first time buying from Unique Camping Marine and we’re very pleased with the customer service and the price of the digestive product that we use. We will definitely do business again."

"Best on the market. We have tried them all and these products beat them all. The new packets save space and time. We had sensor problems since day one with our TT but after using restore-it they work like they should!"
"After using another product, it was a simple decision to move back to RV Digest-It. It does a far superior job of liquefying solid waste, and toilet paper. It is also very effective at reducing odor, and keeping tank sensors functioning properly. We will not consider changing products again"
