No clogs or sluggish flushes so far after a dozen uses. The orange scent is a big win—it’s strong enough to mask any stink without feeling like you’re sniffing a citrus air freshener factory.

In our van build we use a cassette toilet, one of these dropped down in the bottom works wonders, no smell for weekend trips. Not only is there no smell, but there’s a pleasant smell coming from the toilet now—I never imagined those words coming out of my mouth. We usually dump every third or fourth day depending on where we are and how much we’ve used it. These are a must for us at this point now, no more stinky toilet.

Frequently Asked Questions

How Do RV Toilet Treatments Actually Work To Control Odors And Break Down Waste?

When you use an RV toilet treatment, you’re essentially adding enzymes or bacteria that start breaking down the waste and toilet paper in your black tank. This process helps prevent clogs and reduces the buildup that causes bad smells. Many treatments also contain odor-neutralizing agents or fragrances, like citrus or fresh scents, to keep your RV smelling pleasant. You simply add the treatment after dumping your tank or as directed, and it goes to work dissolving waste and controlling odors, so you don’t have to worry about unpleasant smells during your trip.

What Should I Consider When Choosing An RV Toilet Treatment?

You want to look for a product that’s safe for your RV’s septic system and the environment, especially if you dump at campground facilities. Treatments come in different forms like drop-in pods, powders, or liquids, so think about what’s easiest and least messy for you. Also, consider the scent—some people prefer unscented or mild citrus, while others like stronger fragrances. Price is important too; for example, Camco TST MAX Drop-INs cost around $16.99 USD for a 30-pack, which is convenient and mess-free, while Happy Campers’ concentrated granules are about $28.45 USD but last longer per use. Lastly, check reviews to see how well the product controls odors and breaks down waste in real-world conditions.

Can I Use RV Toilet Treatments In Portable Toilets Or Only In Black Water Tanks?

Most RV toilet treatments are designed specifically for black water tanks, but some can work in portable toilets too. However, keep in mind that treatments like Happy Campers require oxygen to work effectively, so they might not perform well in airtight portable toilets. Drop-in pods like Camco TST MAX or Walex Citra-Pak are often easier to use in portable toilets because you just drop them in after each use. Always check the product instructions to make sure it’s compatible with your toilet type, and avoid mixing treatments to prevent chemical reactions or damage to seals and sensors.

Wrapping Up

The eight products featured here offer a range of options from drop-in pods to liquid treatments, all designed to keep your black and gray tanks fresh, odor-free, and functioning smoothly.
