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.

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.

Its bio-enzymatic blend is among the strongest available, making it highly effective at unclogging stubborn blockages in black water systems in RVs, campers, motorhomes, fifth-wheels, and boats.

One significant advantage is its ability to solve both old and new waste problems without damaging tank seals or valves, which is a crucial consideration for long-term RV maintenance. Moreover, the product is easy to use as you simply add it to your tank and wait 48-72 hours, without the need to drive around to aid in the cleaning process. This makes it very user-friendly, especially for those new to maintaining RV holding tanks.

Additionally, it is compatible with home septic systems and is California compliant, which adds to its appeal for environmentally conscious users. However, while it is very effective, some users might find the waiting period of up to 72 hours a bit lengthy, especially if they are looking for a quick fix. Also, this product may not be the most cost-effective solution for regular maintenance given it is typically used for more severe blockages. In essence, this product is best suited for RV owners needing a powerful and reliable solution to tackle significant clogs and waste build-up in their holding tanks.
