Summary of Top RV Toilet Treatments
Product Roundup: What Are the Best RV Toilet Treatments in 2025?
1. Camco TST Orange Power RV Toilet Treatment
Best for: Powerful odor control
If there’s one RV toilet treatment I always recommend for tackling stubborn odors, it’s the Camco TST Orange Power RV Toilet Treatment.
This ultra-concentrated liquid formula is designed to neutralize even the toughest holding tank smells, leaving behind a fresh citrus scent that’s effective without being overwhelming. Whether you’re dealing with summer heat or extended trips, this treatment keeps your RV smelling clean and pleasant.
What really sets the Orange Power formula apart is its ability to break down waste and tissue quickly, making tank dumping much easier and less of a hassle. With just 2 ounces treating up to 40 gallons, it’s both powerful and economical – perfect for RVers who want effective results without constantly reapplying.
Plus, it’s formaldehyde-free and biodegradable, so you can feel confident using it in all septic systems, including environmentally sensitive areas.
While the liquid format offers precision dosing, it might not be the first choice for those looking for the ultimate in convenience, like drop-ins. I’ve sometimes found the citrus scent can feel a bit strong, especially in my smaller RV’s bathroom.
However, if odor control and waste breakdown are your priorities, this treatment is a reliable solution that delivers every time.
The Camco TST Orange Power RV Toilet Treatment has become a staple in my own RV trips, thanks to its dependable performance and eco-friendly design. If you’re ready to keep odors at bay with a product you can trust, this one’s a must-have.

2. Star Brite Instant Fresh Toilet Treatment
Best for: Eco-conscious RVers
If you’re looking for an RV toilet treatment that’s tough on waste but gentle on the environment, the Star Brite Instant Fresh Toilet Treatment is one I highly recommend.
I’ve used it during trips where eco-friendliness was a priority, and it consistently delivered excellent results. Its formaldehyde-free, biodegradable formula gives you peace of mind while keeping your holding tank odor-free.
What I love about this product is its ability to break down waste and tissue quickly, leaving no trace behind – just a clean, fresh lemon scent.
It’s especially great for extended trips since one ounce treats up to 5 gallons, meaning a single bottle can handle a lot of use. This makes it an economical choice, too. I also appreciate how versatile it is; whether you’re using it in an RV, marine toilet, or portable system, it works seamlessly.
That said, I’ve noticed that in hotter climates or with long holding periods, you might need to use a little more than the recommended dosage to maintain its effectiveness. It’s a small adjustment, and honestly, the benefits of using a biodegradable formula far outweigh this minor inconvenience.
The Star Brite Instant Fresh Toilet Treatment has become a go-to for trips where environmental impact matters. If you want something reliable, effective, and eco-friendly, this is a solid choice.

3. Camco TST Fresh Scent RV Toilet Treatment
Best for: Convenience
When it comes to simplicity and reliability, the Camco TST Fresh Scent RV Toilet Treatment is hard to beat. I’ve used plenty of treatments over the years, but these pre-measured drop-ins are by far the easiest option out there.
No spills, no measuring – just drop one into your tank, and you’re good to go.
These packets are great for maintaining an odor-free RV bathroom while breaking down waste and tissue efficiently.
The fresh, clean scent isn’t overpowering, making it ideal for smaller spaces. I also like that the treatment is biodegradable and formaldehyde-free, so you can use it with confidence in any septic system.
What makes these drop-ins stand out is their sensor-lubricating feature. If you’ve ever dealt with faulty tank sensors, you know how frustrating they can be. These packets help prevent buildup that interferes with readings, which is a huge plus for keeping your system running smoothly.
That said, the convenience does come with a bit of a trade-off. If you prefer more control over dosing or need to treat larger tanks, a liquid treatment might work better for you. Additionally, while the resealable packaging is convenient, I’ve heard from a few fellow RVers that it doesn’t always stay airtight after multiple uses – so be sure to store it properly.
For me, the Camco TST Fresh Scent RV Toilet Treatment is a no-brainer for quick and hassle-free tank care. If you’re tired of the mess and guesswork with other treatments, these drop-ins are a game-changer.

Tips for Buying the Best Toilet Treatment for Your RV Setup
Choosing the right RV toilet treatment ensures a fresh, hassle-free experience. Here’s what to look for to keep your holding tank clean, efficient, and odor-free.
Consider Your Tank Size and Usage
The size of your RV’s holding tank plays a big role in choosing the right treatment. Most treatments specify how much they treat – like drop-ins designed for a 40-gallon tank or liquids measured by the ounce.
If you’re frequently dumping smaller tanks, a liquid formula can give you more control over dosing. For larger tanks or extended trips, pre-measured drop-ins are convenient and eliminate guesswork.
Prioritize Odor Control for Your Environment
Odor control is one of the most important factors for a toilet treatment, especially if you’re camping in hotter climates where holding tanks can get unpleasant fast.
Look for products that have strong odor-neutralizing formulas. A fresh scent can also help keep your RV bathroom pleasant but be sure to choose one that isn’t overpowering for small spaces.
Choose the Right Formula for Your Needs
Deciding between liquid and drop-in packets often comes down to your preference and how much effort you want to put into maintaining your system.
Drop-ins are incredibly convenient and mess-free, making them ideal for busy RVers. On the other hand, liquid treatments offer dosing flexibility and are often more cost-effective for frequent tank cleaning.
If you’re concerned about environmental impact, make sure your chosen treatment is biodegradable and formaldehyde-free. This is especially important if you’re camping in areas with strict disposal regulations or using sensitive campground septic systems.
Storage and Shelf-Life Matter
RV space is always at a premium, so consider how easily your toilet treatment can be stored.
Drop-ins often come in resealable pouches that are compact and easy to stash. Liquids require careful handling to avoid spills, but they typically have a longer shelf life. Look for treatments with a 2 to 5-year lifespan to ensure they’ll last through multiple trips.
Consider Additional Requirements or Features
Some toilet treatments go beyond just odor control and waste breakdown by offering additional benefits like sensor lubrication.
If you’ve experienced tank sensor issues in the past, this can be a game-changer for keeping your system functioning properly. Features like these can save you time and money on repairs in the long run.
