Happy Campers Organic RV Holding Tank Treatment

The 10 Best RV Toilet Chemicals for Breaking Down Waste 6

Here we have a very affordable RV toilet chemical for breaking down waste. It’s super easy to use, quick-acting, and long-lasting.

Product Highlights

One of the biggest highlights here is that not only does Happy Campers Organic RV Holding Tank Treatment completely dissolve all waste in an RV holding tank, but it also helps eliminate the smell of sewage. In terms of smell control, it’s one of the best options out there.

A single scoop of this stuff can treat a 40 gallon tank, and each container comes with a total of 64 scoops. Not only is it long-lasting in this sense, but it’s a kind of chemical that only needs to be added to a holding tank once, and will then keep working until the tank is emptied. Another bonus is that this option is still effective in extreme temperatures.

The Good

The best aspect of Happy Campers Organic RV Holding Tank Treatment is the great odor control it provides, not to mention that it is completely bio-degradable and eco-friendly too.

The Bad

When this chemical first hits the water, it forms hard chunks which may or may not break apart, and this can be problematic.

PROS

  • Affordable
  • Simple and effective
  • Great odor control
  • Completely bio-degradable

CONS

  • May form hard chunks in the toilet bowl

Camco TST Orange

The 10 Best RV Toilet Chemicals for Breaking Down Waste 7

Here we have an even more affordable option to go with than the previous one, but that said, it also won’t last nearly as long, so comparably speaking, they come in at about the same price.

Product Highlights

A great thing about this Camco TST Orange is that it’s super simple to use. It comes in little tabs filled with liquid, just like laundry pods. Simply drop them in the RV toilet, flush, and you are good to go. Keep in mind that one single tab can effectively control sewage odors for up to 1 week, although it may take two tabs depending on the volume of sewage in the holding tank.

Moreover, these tabs are marine safe and 100% biodegradable, so you don’t have to worry about harming the environment. On a side note, these tabs do smell like citrus, which most people would agree is quite pleasant. These tabs can even break down waste and tissue, although their performance in this regard is somewhat limited.

The Good

We just like how easy these Camco TST Orange tabs are to use. Just drop them into the RV toilet, flush, and forget about them.

The Bad

While some people like the citrusy scent, there are bound to be those who do not. Moreover, if there is a lot of sewage in the tank, the citrus smell may not completely overpower the smell of sewage, but actually mix with it.

PROS

  • Very easy to use
  • Effective odor control
  • Affordable
  • Eco-friendly
  • Help prevent clogs

CONS

  • Not the best for breaking down waste
  • Some people are not a fan of the smell

Buyer’s Guide

Before you go out and buy any toilet chemical for the break down of waste in RV holding tanks, there are a few things you need to consider.

The Specific Purpose

One thing for you to look into here is what the specific purpose of the RV toilet chemical is. Some are designed primarily for sensor cleaning, some for waste breakdown, some for odor control, and some can do all of the above. You need to find the right product to suit your needs.

Sensor Cleaning 

One very important thing which all RV toilet chemicals should do is to clean the sensors. Sensors get covered with waste buildup, and this makes them not function properly. Having something to help restore and maintain the sensors is a big deal.

Eco-Friendliness

You do want to look for a product that is eco-friendly. The waste from the holding tank will have to be dumped eventually, so anything you put in the tank will make its way back to the earth. Finding a formula that is free of formaldehyde, non-toxic, and eco-friendly is a big deal.

Odor Control

Most of these products will do a good job at controlling odors, but some better than others. Something to think about here is if you want something that will simply eliminate odors or if you want something that will also cover them up with a different scent.

Staining

Just be careful if you go for an option that is colored, such as green or blue, as these dyes can often stain clothing and other things.

The Specific Instructions 

Always pay attention to the specific instructions on the bottle or packaging. These products are often a bit finicky and will only work when the directions are closely followed.

FAQs

Can you use toilet bowl cleaner in an RV?

You can use normal toilet bowl cleaner, however this will only keep the toilet clean, and will do nothing for the tank itself.

Can you use bleach to clean a holding tank?

In no case should you pour bleach into the toilet or holding tank of your RV. Bleach usually contains chlorine, which can damage plastic, gaskets, and sensors too.

Can you dump RV grey water on the ground?

No, it is completely illegal to dump RV water on the ground, and yes, there are some pretty heavy fines for doing so.

What is the best way to clean an RV holding tank?

Generally speaking, a bacterial formula that uses enzymes to break down waste will take care of most issues associated with RV holding tanks.

Final Verdict

Due to ease of use, we personally would recommend any of the options that come in little tabs. Camco TST Orange, Walex Porta-Pak Holding Tank Drop-ins, and the RV Septic Tank Treatment would be our top picks. They are affordable, easy to use, and very effective too.
