But the primary purpose of these tank treatments is getting rid of those nightmare situations that happen in RV septic systems such as clogs or blockages. Therefore, if you have a clogged toilet, you just use one of these products, and it should no longer be an issue.

Plus, it also helps in digesting sludge and other waste materials, which can cause all sorts of problematic issues inside your RV. And some of them will even remove the odors these situations leave behind with their fragranced scent.

With all this in mind, it’s becomes quite clear why having a top-notch RV tank holding treatment around your RV is a good idea. It’s just an effective and quick solution to terrible situations that nobody wants happening on their relaxing RV trips.

How does it work?

Using an RV holding tank treatment is remarkably simple. All you need is either drop or pour it into the toilet bowl depending on the type you’re using. After doing so, you flush it and let the treatment soak.

From there, the treatment will do the rest of the work as it’ll start treating your septic tank quickly and effectively. Some brands even treat up as much as 40 gallons of wastewater per session, which is a pretty significant amount of water.

These products are so fantastic at their jobs that’ll treat both the toilet and the septic system while deodorizing them as well. All in all, you can see that using these products isn’t a complicated process like you might see with other RV related products.

It’s instead something that even someone who isn’t an experienced RVer can reasonably handle without incident or complications.

Does an RV holding tank treatment clean the tank’s sensors?

It’ll depend on your chosen tank treatment. Still, most of them are formulated to clean a tank’s sensors while removing the waste inside your rig’s holding tank.

Manufacturers will be forward with any tank treatment with this ability. After all, cleaning tank sensors is often a massive issue for most RVers. Choosing a septic safe RV tank treatment that can clean the sensors becomes convenient.

But I’d refrain from choosing an option with formaldehyde. These options cause damage inside RV septic tanks. It’s also best to avoid using homemade RV holding tank treatment products.

Instead, stick with the options that experts recommend using. They’ll ensure your rig’s holding tanks remain in peak condition without issue. Each tank sensor cleaning option mentioned in our article should be more than capable of doing the task.

How do I get rid of RV holding tank odors?

Your first step is buying a tank treatment or RV waste digester with odor-killing capability.

Several of the options mentioned in our article provide this feature. It then becomes about following the included directions to eliminate those awful smells.

If you have questions about tank treatments, refer to our “How to use this product in RV?” section. It’ll provide a general guide about utilizing these products within your rig. But please don’t only rely on this section.

Most RV grey water tank treatment or black tank treatment products will require different steps.

Thus, it would be unwise not to follow their packaging or manual when using them.

If you follow them correctly, any tank smells should go away quickly. I’d also do a deep dive into each product’s reviews to evaluate its odor-killing abilities. These resources will help you determine which formula can do the job.

How often should I use RV holding tank treatment?

I can’t provide a general answer for how frequently to use these products. It would make all our lives much easier if there were one. It ends up being a more complicated discussion due to several factors.

People who travel with more people will need to use it often. Meanwhile, if I’m traveling alone, I can manage to refrain from using it for a long time.

Some RVers have even gone a week or two without needing to use holding tank treatment.

But it’ll also depend on your tank’s size. If you have a smaller one, it’ll need holding tank treatment more frequently. Larger tanks can last a little bit longer without needing any extra treatment.

If you account for these factors, it won’t be difficult to figure out the correct usage rate. You’ll likely settle between every couple of days and once a week.

Is a black tank different from a gray tank?

Black tanks and gray tanks are different parts of the RVing experience. You need to understand what’s the purpose behind both of them.

Let’s start with the gray tank, which contains all the water from your rig’s plumbing. Everyday activities like showering are possible with your rig’s gray tank. But what it won’t have is the waste or water coming from the toilet or septic system.

Instead, you can expect the black tank and chemicals for RV black tank to handle it. If you flush a toilet, the water/waste will go into your black tank. It’s the grosser one between RV’s gray and black tanks.

I also must mention that black tanks can’t empty into anything other than a septic system. Otherwise, there’s a significant risk of spreading bacteria and disease.

What are the most trusted RV holding tank treatment brands?

The top RV holding tank treatment manufacturers are the ones listed in our product review section. These companies are continually outpacing their competition with the overall effectiveness and convenience of their products.

But even among this group of fantastic manufacturers, there are a couple that stand out a little more than the others: Camco, Walex, and Thetford. And in this section, we’re going to give you a little background information on each that’ll provide an insight on how they stay above their competitors.

Camco

A favorite manufacturer among RV owners, Camco has been a leader in the RV part industry for what feels like forever. They cultivated this great relationship with their customers through taking “pride in meeting the ever changing demands of a challenging marketplace while serving [their] most valuable asset, [their] customers.”

And nothing has changed with their extension into the RV tank treatment marketplace as you can tell from the Camco products in our product review section.

Walex

As one of the leading RV holding tank treatment manufacturers in the world, Walex has become a brand that RV owners trust. And they’ve done so by dedicating, “significant resources to continual research and development so that [they] can offer new products and enhancements, and identify cost effective solutions for [their] customers.”

It’s dedication like described above that makes me and should entice you to buy from this particular manufacturer.

Thetford

Being one of the leaders in the mobile sanitation product industry, it’s no surprise that Thetford does an amazing job creating RV holding tank treatments as well. It’s able to do so through priding “itself on creative design and is committed to the production of high-quality products that exceed the needs of a demanding marketplace.”

If you’re lucky enough to buy from any of these three companies, I’m sure you’ll be satisfied with the product you end up getting. These three are the best of the best, and all their products are always top-notch.

Where to buy RV holding tank treatments?

The best place to buy RV holding tank treatments would be Amazon as they’ll have the best deals and the most options. After all, there’s a reason all the products mentioned in this article have links to the site.

Of course, you do have other sources available to you as a prospective RV holding tank treatment buyer. You could try checking out a site like Campingworld.com and seeing what deals they have to offer.

In most cases, their deals will be worse than the ones you’d see at Amazon; however, it doesn’t hurt to compare the two sites just in case. You never know when something might pop up at a discount rate on a site like Camping World.

Now, if you have an aversion to online shopping, Walmart, Home Depot, or your local RV part store should have some options. But again, the selection will be incredibly limited compared to what you’d see online. And it’ll probably be more expensive as well.

All in all, I’d recommend sticking with Amazon as your primary provider for RV holding tank treatments. It will offer you the most choices and the best deals, which is all you can ask for in a marketplace site.

But you should always compare their prices with sites like Camping World to ensure you can’t get a better deal elsewhere.
