After trying out the Camco TST MAX, I'm convinced it's a reliable solution for maintaining a fresh-smelling and clean RV toilet system.


  • Substantially reduces odors
  • Simplifies the maintenance process
  • Eco-friendly and safe for septic systems


  • Limited effectiveness in extremely hot weather
  • Single scent option may not appeal to all
  • Requires consistent use for best results

The convenience of the Camco TST MAX Drop-INs can't be overstated. Popping one into the RV toilet was effortless, and it immediately went to work, breaking down waste and keeping sensors clean. Freshness was unmistakable with its orange scent, which provided a lasting pleasant aroma throughout the vehicle. The biodegradable nature of these drops offered peace of mind, aligning with my preference for environmentally responsible products.

However, during a midsummer trip, the product's ability to neutralize odors was challenged by extreme temperatures. While it didn’t fail utterly, a more frequent application became necessary. Additionally, variety is the spice of life, but this product sticks to a single citrus fragrance, which, while refreshing, might not cater to everyone's tastes.

In spite of these minor hurdles, the overall experience was positive. Regular usage is key to maintaining a trouble-free, odorless RV toilet. The Camco TST MAX is well-suited for those seeking an effective, user-friendly treatment for their RV sanitation needs.

Treat your RV to odor-free adventures with Happy Campers Tank Treatment, a proven solution even in extreme temperatures.


  • Neutralizes odors skillfully
  • Environmentally safe for septic tanks
  • Enhances breakdown of waste and toilet paper


  • Some tanks may require an extra dose
  • Initial cost may seem high
  • Not a scented solution for those preferring fragrance

While recently traveling in my RV during a particularly sweltering summer, I found the Happy Campers RV Holding Tank Deodorizer to be a standout choice. It managed odor exceptionally well, and despite the heat, my rig stayed smell-free. Its septic-safe feature is great for the eco-conscious camper, ensuring we leave a minimal footprint behind.

However, I did come across a situation where I had to add a little more than the suggested amount due to extended use between dumps. While it's not a ‘one-size-fits-all', the overall effectiveness justifies the extra scoop.

Additionally, the cost might give the occasional traveler pause, but for regular RVers, it's an investment in comfort and hygiene. While there's no fragrance, which I personally prefer, those who like a fresh scent may miss that element.

Embrace the Happy Campers life; keep rolling without the unpleasant holdups of tank odors or troublesome waste.

3. AquaMAX Treatment by Thetfor – Great Value

  • Provides a refreshing spring showers scent that combats odors efficiently
  • Eco-friendly and California compliant, making it a responsible choice

Using Thetford's AquaMAX, you’ll notice a swift action against waste accumulation, preventing those dreaded clogs and clumping. Its fresh scent does an admirable job at keeping odors in check, leaving you with a pleasant environment. As an eco-conscious traveler, it’s fulfilling to know that this product doesn’t rely on formaldehyde or bronopol, aligning with your green principles. On the flip side, its notably effective treatment comes at a price that may pinch the wallet slightly more. While the scent strikes a pleasing note, those with a keen sense of smell might find it overpowering at times. Frequent adventurers be warned, as the 8oz bottles may run out quickly, nudging you towards a sooner-than-expected repurchase. Yet, these are minor trade-offs for a product that delivers consistently on performance and environmental safety.

After a weekend getaway, I used the Green Gobbler's pods and was impressed by the immediate dissipation of odors, a crucial comfort factor in close quarters. The convenience of dropping a pod into the toilet without measuring liquids meant more time to relax. While the unscented formula promises an odorless experience, some lingering smell was noted, but nothing my usual air freshener couldn't handle. As a seasoned traveler, I found that, for extensive use or larger holding tanks, tossing in an extra pod maintained the pristine condition of the system. Overall, Green Gobbler delivers a hassle-free, efficient waste management solution for RV owners.

Expect a remarkably fresh and clean experience for your RV toilet with the convenience of Walex Porta-Pak Deodorizer.


  • Hassle-free usage with just a single drop-in packet
  • Effective odor control suitable even for high temperatures
  • Safe for a range of septic systems as it's free from harmful chemicals


  • Some users may require extra packets for extended periods
  • The scent might be too mild for those preferring stronger fragrances
  • Limited effectiveness reported by users with full-time RV living

After recently trying the Walex Porta-Pak Deodorizer, the simplicity of using a pre-packaged sachet was a game changer. It eliminated the clumsy measuring and potential spills associated with liquid treatments. When it came to odor suppression in various climates, it demonstrated robust performance, and the Clean Linen scent left a subtle, fresh aroma that didn't overpower the senses. Despite its potency, on busier weeks, an extra sachet was necessary to maintain optimal freshness.

Given that it's formulated without formaldehyde and other harmful substances, it felt good knowing it is gentle on the environment. The sachets dissolved swiftly, making cleanup and maintenance tasks less of a chore. One drawback to consider, however, was feedback from some full-timers who didn't find the product as effective as desired, implying that for constant use, there might be better suited products out there.

In any case, for those occasional trips or moderate RV use, the Walex Porta-Pak is a solid choice, facilitating a more pleasant and carefree journey.

Consider the Eco Strong RV Toilet Treatment for a fresh-smelling and clog-free waste management system in your RV.


  • Efficient waste breakdown
  • Effective odor control
  • Sensor cleaning feature


  • May require more than directed
  • Only available in liquid form
  • Lavender scent might not appeal to all

After trying out the Eco Strong RV Toilet Treatment, the immediate effect it has on keeping your RV's toilet area odor-free is quite impressive. Its bio-enzymatic formula seems well-suited to liquefying waste without the need for harsh chemicals, making for an environmentally-friendly option. Cleanup became far simpler, with the sensors staying clear and providing accurate readings.

However, the claim of all-natural ingredients means this formula may require a liberal application, more so than what's mentioned in the instructions. The fact that it's liquid may put off enthusiasts who prefer the convenience of pods. The lavender scent, while pleasant, could be too specific for some users, but it certainly adds a nice touch to the overall freshness of the holding tanks.
