Works Great

This product brought my sensors back to empty readings after a very long time of unreliable level indications. I used as directed for 3 days undisturbed.

Great product

Worked great when I flushed the tank there was no solid waste, everything was liquid. Love this product

Love it!

Does an amazing job at cleaning the sensors. Thank you!

Finally….A tank cleaning product that WORKS!

I’ve been an avid user of pine-sol and Calgon method for years. Liquified has really surprised me with its effectiveness of waste breakdown and odor control.

I highly recommend Liquified!

Works the Best of all I’ve tried

I did my own test of different chemicals for my black tank. I put the same amount of paper in a cup trying to replicate my tank. This chemical broke down the paper better than my previous brands I have used.

Excellent product

Works great and I’m glad to support an entertaining content creator that works hard to produce good content.

This product worked as it is intended

Awesome

What a great product from a very humble group of folks. Liquified is a great product and I try to convert people over to it when I’m camping. I actually sold a bottle a week ago to a fellow RV’r for quite a bit less than I paid for it, just so he could become familiar with your product and pass it onto others. Keep up the good work and stay humbled.

Works wonderfully

Works great and smells awesome after 1 week camping trip

Excellent product!

works great

Works well and smells great.

Works great. We ordered the blue but the post office lost are order. We let you know and you replaced it no charge to us. We will continue to buy Liquify.

Fresh

I used the tank and sensor cleaner on my tank and left it for
24hr. the sensors are reader empty now and it smell great to.
I would recommend this product.

Smells like

We have tried all kinds of RV toilet treatments, most are a waste of time and money, but Matts Liquified is by far the best toilet treatment we have used. smells really clean and citrussy. Now this is a prime pooping position!!!!

Great product

This tank treatment works exactly as described. The easy dose bottle is a nice touch. No more dusty powders or guessing (I never measured liquids) at the amount to add. I saw a video about the dual cap bottle and the challenges in production and shipping. A great product made by a small US business for a small US business. I highly recommend this product.

Works Great, As Advertised.

Awesome stuff

Works wonderful! No smells and I see no toilet paper when emptying my tank!

Great product. Works like it is advertised

Black tank showed 2/3 full even though emptied. Used this product as directed and black tank shows empty again. Will definitely use this product again.

Works great for us

We have used Matt's Liquified RV Toilet Treatment for about 6 month now, and it has been working great for us! I highly recommend it.

Tank cleaner

I would say it works pretty good for helping clean out your black tank. I would use it probably once a year or so. I filled the black tank half way with fresh water and a bottle of the cleaner then towed it a good distance and then let it sit a few days. When I dumped it it was very dirty and prior to putting the cleaner in it I rinsed it several times and even completely filled and dumped it and it was as clear as could be so it definitely cleans better than what you can do by just rinsing.

Best tank cleaner ever!

We have used a couple of different tank cleaners. Our sensors have not shown empty in 3 years. Finally tried this cleaner and let it soak for a week, because gotta go to work. My husband was finally able to dump and rinse today. And we have sensors reading empty!

The best I have used.

I really notice the difference when we have long stays and I can keep the black talks closed for about 8-10 days. It certainly liquifies and dissolves the paper.

Smell is gone!

This stuff works great, without needing multiple treatments. Just leaves a pleasant orange scent. Happy to recommend liquified to others.

2nd time ordering

2nd time ordering 2 bottles. Nothing works better.

like this a lot

Tried for over a month in the hot Arizona desert. Works great to control the smell and keep my black tank sensors happy. Like this better than the prior powder product I was using.

Best decision ever!

What can I say. This stuff just freakin’ works! It’s the only tank treatment we’ll be using from this point on! And the orange scent doesn’t hurt a bit…
