Best RV Tank Cleaner: Reviews

1. Walex TOI-91799 Porta-Pak Holding Tank Deodorizer

If you need an effective product to help deodorize your RV holding tank, this is a good choice to go with. It also helps to break down waste and toilet paper, but its main purpose to get rid of that horrible holding tank smell.

It is a very affordable and easy to use as well.

Review

Walex TOI-91799 Porta-Pak Holding Tank Deodorizer is very easy to use. Here you get 10 deodorizer tabs, and each of them just needs to be dropped in the RV toilet and flushed.

1 tab will last for 7 days, so the whole pack will last for nearly 2 months. Being cost effective and easy to use are both big benefits.

What is also nice about Walex TOI-91799 Porta-Pak Holding Tank Deodorizer is that they have no formaldehyde in them. They are not 100% ecofriendly, but they are better for the environment than other alternatives.

Of course, the best part about this product is the fact that it is an excellent deodorizer and will get rid of all kinds of waste smells. This is where Walex TOI-91799 Porta-Pak Holding Tank Deodorizer excels.

This product also breaks down waste and toilet paper to a certain extent, but it’s not the best at it. This product is meant primarily for controlling odors over anything else.

With that being said, it keeps your tank cleaner and flowing more freely than it would be without any treatment at all.

On a side note, the scent of these tabs is called “Sun Glow,” which sounds nice, but some people actually don’t like the smell.

Pros

  • Easy to use
  • Cost effective and long lasting
  • Great for odor control

Cons

  • Some people don’t like the scent
  • Not the best for waste breakdown

2. Walex TOI-61776 Elemonate Grey Water Deodorizer

This is another fairly good option to go with if you need to clean and deodorize the holding tank of your RV. Once again, while this does an all-right job at breaking down waste, its main purpose is to get rid of odors.

Walex TOI-61776 Elemonate Grey Water Deodorizer is a very long-lasting and fairly cost-effective solution.

Review

Walex TOI-61776 Elemonate Grey Water Deodorizer comes with 5 individual tablets in a single package. 1 tablet is enough to treat a large 60-gallon RV holding tank.

Therefore, it is very long lasting, and 1 tablet should be enough to last for a couple of weeks at the least, plus there is also the fact that they are quite cheap. Moreover, all you have to do is drop a tablet in the toilet, flush, and forget about it.

It’s as easy as that. It has a fresh lemon scent, which helps mask bad odors, while also deodorizing and neutralizing smells on its own.Some people may not like the lemon scent, but it’s still better than the alternative.

At any rate, Walex TOI-61776 Elemonate Grey Water Deodorizer is also an effective tool because it helps to dissolve grease, sludge, and solid waste to keep the pipes clear and to allow for easy emptying of the holding tank.

Something that we like about Walex TOI-61776 Elemonate Grey Water Deodorizer is that it is fully biodegradable and will not hurt the environment. We think that this is always an important factor to keep an eye out for. 

Pros

  • Long lasting and cost effective
  • Good deodorizer
  • Keeps pipes fairly clean

Cons

  • Some people may not enjoy the lemon scent
  • May stain porcelain and plastic if not washed down immediately

3. Walex PPRVLAV Porta-Pak Holding Tank Deodorizer Drop-Ins

If you like smell of lavender, you might become a fan of these Walex PPRVLAV Porta-Pak Holding Tank Deodorizer Drop-Ins.

In all reality, besides the smell difference, they are more or less exactly the same as the first product we looked at, but with a lavender scent instead of the so called “Sun Glow” scent.

Review

When you buy Walex PPRVLAV Porta-Pak Holding Tank Deodorizer Drop-Ins, you get a total of 10 drop in tabs. Each tab can last for up to 1 week at the most, so a whole pack will last you nearly 2 months.

Considering the low price, this is not bad. It’s fairly long lasting and cost effective. Also, the fact that you can simply drop them in the toilet, flush, and forget about them, is quite convenient.

We like how they are formaldehyde-free; Walex PPRVLAV Porta-Pak Holding Tank Deodorizer Drop-Ins are not totally eco-friendly, but still better than many alternatives. Yes, this stuff will break down waste and toilet paper, although not as fast as some other products.

Where Walex PPRVLAV Porta-Pak Holding Tank Deodorizer Drop-Ins really excel is with odor control. They do a fantastic job at controlling odors, but still, some people do not appreciate the lavender scent which this product creates.

Pros

  • Formaldehyde free
  • Good for odor control
  • Helps to keep pipes and tanks running freely
  • Cost effective

Cons

  • Needs to be done once per week
  • Some people don’t enjoy the lavender scent

4. Unique RV Digest-IT Holding Tank Treatment

If you need a product to clean the pipes in your RV, break down waste, and keep the holding tank in prime condition, Unique RV Digest-IT Holding Tank Treatment is one of the best options out there.

It’s inexpensive, it works well, and is quite easy to use.

Review

The No. 1 purpose of Unique RV Digest-IT Holding Tank Treatment is to dissolve solid waste in the RV holding tank.

It is a very fast-acting formula that begins to break down waste on contact, and keeps working until everything is liquefied; it can even break down toilet paper.

It’s a good option for keeping pipes clear, for preventing clogs, and for making the holding tank easy to empty. We like how Unique RV Digest-IT Holding Tank Treatment is truly eco-friendly, non-toxic, and biodegradable.

It will not harm the environment, which we think is important.

Unique RV Digest-IT Holding Tank Treatment does do an all-right job at neutralizing and controlling odors, but not the best, as this is not its primary purpose, but it’s still better than nothing at all.

On a side note, we like how it is 100% manufactured in the US. We also like how Unique RV Digest-IT Holding Tank Treatment lasts for quite some time; one single bottle should last you for a couple of months, and it does not even cost that much either.

Pros

  • Great for breaking down waste
  • Prevents clogs
  • Made in the US
  • Cost effective

Cons

  • Not the best for controlling odors
  • Does not smell that great

5. Caravan Full-timer's RV Holding Tank Treatment

This final option on our list today is another fairly good one. It is a simple powder treatment that just needs to be flushed down the toilet every once and a while.

It is super easy to use, does not cost too much, should last for a couple of months, and does a good job.

Review

Caravan Full-timer's RV Holding Tank Treatment is a good option for a couple of reasons. First off, it appears to be one of the more cost effective options out there.

This particular bottle will last for 16 separate treatments, and it only needs to be used when you empty the holding tank, before you start filling it again.

When it comes down to it, Caravan Full-timer's RV Holding Tank Treatment will probably last longer than any other option on our list, which is especially impressive considering the low price.

We like how Caravan Full-timer's RV Holding Tank Treatment is eco-friendly and safe for pets, kids, and the environment. Moreover, it does a really good job at breaking down waste and preventing odors.

It does not excel at deodorizing as much as it excels at breaking down waste, but overall, it works well. Simply pour the recommended amount in the toilet, flush it, and you are good to go.

Pros

  • Very lost lasting and cost effective
  • Simple to use
  • Good for preventing clogs and breaking down waste

Cons

  • Powder can be a bit messy

Conclusion

When it comes down to it, the option we would most highly recommend here is the Unique RV Digest-IT Holding Tank Treatment. It might not be the best for odor control, but it works wonders at breaking down waste. If you need something that is better for odor control, we would recommend any of the first 3 products we reviewed.
