Buying Guide
Choosing the right RV holding tank treatment can seem overwhelming, but breaking it down into a few key considerations makes the process much easier.
- Treatment Type: There are primarily two types: enzymatic and chemical. Enzymatic treatments use bacteria and enzymes to break down waste naturally, making them environmentally friendly and often better at eliminating odors. Chemical treatments use chemicals to mask odors and liquefy waste, but they can be harsher on your plumbing and the environment.
- Odor Control: This is a big one! Look for treatments that actually eliminate odors, not just cover them up. Read reviews to see what other RVers say about the product’s odor-fighting abilities, especially in hot weather.
- Waste Breakdown: A good treatment should effectively break down solid waste and toilet paper to prevent clogs. Enzymatic treatments are generally better at this than chemical treatments.
- Ease of Use: Do you prefer drop-in packets, liquid treatments, or powders? Consider your personal preferences and how easy the treatment is to use and store. Drop-ins are super convenient, while powders often offer a more concentrated and cost-effective solution.
- Environmental Impact: If you’re concerned about the environment, opt for an enzymatic treatment that is biodegradable and septic-safe.
- Tank Compatibility: Make sure the treatment is compatible with your RV’s plumbing system and tank materials. Some treatments can damage certain types of seals or components.
- Price: Holding tank treatments vary in price, so consider your budget and how often you’ll be using the treatment. A more expensive treatment may be more concentrated and last longer, making it a better value in the long run.
FAQs
Q: How often should I treat my RV holding tank?
A: It depends on the treatment you’re using and how often you use your RV. Generally, you should treat your tank after each dumping, or as directed by the product instructions. For drop-ins, it’s usually one packet per dump. With enzymatic treatments, adding some water helps activate the process.
Q: Can I use regular toilet paper in my RV?
A: It’s best to use RV-specific toilet paper, as it’s designed to break down quickly and prevent clogs. If you must use regular toilet paper, choose a thin, single-ply option and use it sparingly.
Q: What is the best way to clean my RV holding tank?
A: There are several ways to clean your RV holding tank. You can use a tank rinser that connects to your sewer hose, or you can fill the tank with water and a tank cleaning solution and let it soak before dumping. Avoid using harsh chemicals like bleach, as they can damage your tank and plumbing.
Q: Can I use the same treatment for both black and gray water tanks?
A: Some treatments are specifically designed for black water tanks, while others can be used in both black and gray water tanks. Check the product label to ensure it’s suitable for your needs. Gray water tanks can also benefit from treatment to prevent odors and buildup from food particles and soap residue.
Q: What happens if I use too much holding tank treatment?
A: Using too much chemical treatment can damage your tank sensors and seals over time. Too much enzymatic treatment might not cause damage, but it’s usually a waste of product. Always follow the manufacturer’s instructions for the correct dosage.

Keeping your RV holding tanks clean and odor-free doesn’t have to be a headache. With the right holding tank treatment and a little bit of maintenance, you can enjoy your RV adventures without worrying about unpleasant smells or messy clogs.
