The citrus scent is really pleasant and effective.
Ease of Use
These drop-ins are extremely easy to use, just drop them in and they work.

The Camco TST MAX Camper/RV Toilet Treatment Drop-INs offer a convenient and effective solution for managing RV holding tank odors and waste. This type of cleaner is a drop-in tablet, which simplifies the application process and ensures you get the right dosage every time. The chemical composition features advanced odor-eliminating technology that promises to control unwanted smells for up to 7 days, which is quite effective for longer trips. The orange scent adds a refreshing touch, replacing unpleasant odors with a pleasant citrus fragrance.

When it comes to waste breakdown efficiency, these drop-ins excel at breaking down waste and toilet paper, which can help prevent clogs and improve sensor performance in your tank. They are also safe to use with septic systems, making them a versatile choice for various camping setups. Compatibility with tank materials is generally good, as the cleaner is designed for use in RV and marine black water tanks, and should not cause damage to your holding tank materials.

As for ease of use, the drop-in form is very user-friendly, eliminating the need for measuring or handling liquids. A minor drawback might be that it requires a drop-in for every 40-gallon tank, so keeping track of usage is necessary. Additionally, while the advanced chemistry is intended to be safe, those with chemical sensitivities might want to handle with care. In conclusion, this product is well-suited for RV enthusiasts looking for an easy-to-use, effective solution to maintain their holding tanks and control odor.

The Unique RV Digest-It+ Extra-Strength Black Tank Treatment is a powerful option for RV owners looking to manage their black and gray water tanks effectively. It stands out for its ability to quickly break down waste and toilet paper, making dumping easier and preventing clogs. The formula is stronger than the classic version, which means it’s particularly effective at eliminating foul odors and managing waste breakdown efficiently. This makes it great for various camping styles, including those with hookups, dry camping, or full-time living, even in extreme heat conditions.

It’s also designed to keep sensor probes functioning correctly by preventing waste buildup on them, which can be a common issue in RV tanks. One of the notable features is its compatibility with all types of tank materials, as well as its ability to digest grease, oil, and food debris in gray tanks, adding to its versatility. Additionally, the cleaner is family-owned, formulated, and manufactured in the USA, and is compliant with California regulations, ensuring safety for both campground and home septic systems.

However, one potential drawback could be its liquid form, which might be less convenient to handle compared to tablet or powder forms for some users. Although it may be more expensive than some other options available in the market, for those looking for a reliable and strong RV tank treatment, this product offers a well-rounded solution with its combination of odor control, waste breakdown efficiency, and ease of use.

Odor Control
It eliminated odor better than any product I’ve used!
Waste Breakdown Efficiency
The tank finally shows empty after using this cleaner and letting it sit for 3 days.

The Unique Clean-It RV Black Tank Deep Cleaner Liquid is designed to be a powerful solution for maintaining your RV's black tank. This cleaner works within 48-72 hours and claims to be more effective than traditional cleaning wands. One of its standout features is its use of billions of enzymes and probiotics, which help break down waste and eliminate odors without damaging seals or valves, making it safe for long-term use in your RV or boat.

This product is particularly good at reaching and cleaning even the hard-to-reach corners and crevices of the tank, preventing future clogs and buildups. It's also designed to be effective with all types of toilet paper, which is a notable convenience factor. However, it's important to note that it requires a couple of days to work effectively, which may not be suitable for users needing immediate results.

With a size of 32 fluid ounces, it is designed for single-use applications, which might be seen as less convenient for those who prefer multi-use products. On the plus side, its ease of use is enhanced by the fact that you don't need to drive your RV to make it work, and it is compatible with both household and campground septic systems. This product seems to be a strong contender for anyone looking to maintain their RV's sanitation system efficiently and safely.

Buying Guide for the Best Rv Holding Tank Cleaner

Choosing the right RV holding tank cleaner is essential for maintaining the hygiene and functionality of your RV's waste system. A good cleaner will help break down waste, control odors, and prevent clogs, ensuring a smooth and pleasant RV experience. When selecting a holding tank cleaner, consider the following key specifications to find the best fit for your needs.
Type of CleanerRV holding tank cleaners come in various types, including liquid, powder, and tablet forms. Liquid cleaners are easy to use and mix well with the tank contents, making them effective for immediate cleaning. Powder cleaners are often more concentrated and can be stored easily, but they require proper mixing with water. Tablet cleaners are convenient and pre-measured, ensuring consistent use. Choose the type that best fits your convenience and storage preferences.
Chemical CompositionThe chemical composition of the cleaner determines its effectiveness and environmental impact. Some cleaners use harsh chemicals like formaldehyde, which are very effective but can be harmful to the environment and your health. Others use enzyme-based or biodegradable formulas that are eco-friendly and safer to use. If you are environmentally conscious or have sensitivities to strong chemicals, opt for a biodegradable or enzyme-based cleaner.
Odor ControlOdor control is a crucial aspect of RV holding tank cleaners. A good cleaner should effectively neutralize and control odors, keeping your RV smelling fresh. Cleaners with strong deodorizing properties often contain fragrances or odor-neutralizing agents. If you are sensitive to strong scents, look for cleaners that offer odor control without overpowering fragrances.
Waste Breakdown EfficiencyThe primary function of a holding tank cleaner is to break down waste and toilet paper to prevent clogs and ensure smooth tank emptying. Cleaners with high waste breakdown efficiency will reduce the risk of blockages and make the dumping process easier. Look for products that specifically mention their ability to break down waste quickly and effectively.
Compatibility with Tank MaterialsIt's important to ensure that the cleaner you choose is compatible with the materials of your RV's holding tank. Some cleaners may be too harsh and can damage the tank or its components. Most RV holding tanks are made of plastic, so look for cleaners that are safe for use with plastic tanks. Always check the manufacturer's recommendations to avoid any potential damage.
Ease of UseEase of use is another important factor to consider. Some cleaners require precise measurements and mixing, while others are pre-measured and ready to use. If you prefer a hassle-free cleaning process, opt for products that are easy to use and require minimal preparation. This will save you time and effort, especially during long trips.
