Finally, a solution for grey tank odor!

I tell every RVer I meet about Liquefied. I love the black tank products and now I have a solution for grey tank odors, as well!

Awesome stuff!

This is the best tank treatment we’ve ever had and we’ve been Rving since 2018. Our sensors were always reading full no matter how many times we flushed our black tank. After a summer of camping, dumping tanks, and more camping our sensors are reading “Empty” on our blank tank. I know we probably shouldn’t have but I may have added a little to our gray tank. But now we’ll give the gray tank cleaner a try on our next trip in October. We’re a customer for life with Liquified now!

Great Product / Great Scent

We were having some gray water odor issues from our shower. My wife added Liquified via the shower drain and the odor problem was resolved. We really like the lavender scent.

Awesome product

I was a little bit skeptical at first but after even the first use I have been very impressed with this product. It does exactly what the name says. Not only that but we have yet to have any odor issues inside the RV. We will never use another brand from here on out. This product is truly awesome!

Great product!

Great product I will definitely purchase again!

Works

Works as well as the black tank treatment. Glad to finally get a treatment specifically for the gray tank.

Cleanin Turd Tanks

I’ve been using Matt’s cleaning products since they started up. Their products are worry free & hassle free. It’s always comforting to know that my turd tanks are always in great shape after dumpin and runnin. Thank you for your products and stay humble

First Time for Gray Tank

I’m glad I found this gray tank cleaner from Liquified, I use the black tank cleaner and it works great so I’m using the gray tank cleaner to help keep them clean plus it smells amazing.

Works GREAT, and bought MORE!

I used this in our black tank (that always read 1/3 full even after flushing it with the black tank flush for 15-20 minutes each time after dumping) and it reads empty now! And, it has continuously read empty since using the tank and sensor cleaner. I have 3 on hand now that I plan on using as a preventative maintenance every 3 months. Thanks!

Works great

Just finished a tank clean and this stuff works fantastic. There was stuff caked on sides of tank that all gone now.
Will definitely use it again when needed. Next step is the Liquify treatment. Will get tested this weekend. Dry camping for the weekend.

Great product

I have been using Liquified for some time now. I love the scent and how easy it is to measure out the amount that you need.

fresh smell

I used the tank cleaner and the first time in 3 years my sensors worked again so I purchased the tank treatment for black and grey tanks gives it a fresh smell no sewer smell I have tried other products and this one seems to work the best

Best RV sewer tank chemical

I’ve used Liquified since it first came out. As soon as I heard Matt talk about his grey tank chemical I ordered 2 bottles. We winter in Florida with a travel trailer and RV in Minnesota in a Class C motorhome. We use Liquified exclusively and have not had any problems with smells, clogs or residue in our tanks. I’m sure the Liquified grey tank chemical will work very well. I have used the Liquified black tank in my grey tank and it worked well however I’m sure the Liquified grey tank formula will dissolve hair and grease better.

Best tank cleaner

I've tried every home remedy and multiple other products to clean my gray and black water tanks with no luck. I gave this product a try and was blown away by not only the tank sensor reading but how much stuff came out of my tank after soaking a few days.

Works great!

Awesome!! Fast delivery, great product.

Great product

Work great!

Great Product

I’ve only been RVing since May 2024 in my new Brinkley. Began using Liquified right away and love the product. Since using I have added additional Liquified products to help with cleaning the toilet and the black tank.

Awesome Tank Treatment

We love the liquified. The product breaks down solids and makes tank cleaning much faster and more pleasant! The wife uses the treatment as a bowl cleaner too! It perfect for cleaning the toilets!

One Satisfied customer !!

I have struggled with the correct sensor read out on the black tank for years. I put this product in and waited approximately 24 hours and emptied the tank and the reading now says zero!!!!

Awesome!!

Works great.

Works great

Tried it once, then went back to store brand. Had to order on line what a big difference. We will keep it on hand!

Works great (when properly used)

I have been using this and the orange scent for over a year, they work great at controlling odor and breaking down solids in both the Black and Gray tanks! A few things I do to make sure I get the best results, #1 I always put a few gallons of water back into an empty tank, especially when I'm traveling. #2 I'll add an extra dose if the outside temperature is over 90 degrees (my tanks are not insulated). #3 I'll add more every week or so regardless if I've used the RV much or have dumped. I have gone weeks without dumping, due to the RV not being actively used and not near a dump station, and no odor problems.

⭐️⭐️⭐️⭐️⭐️

This stuff works so well, we're convinced it’s secretly powered by unicorns. Our RV bathroom smells so fresh now, even the skunks outside are jealous!

Clean tank sensors!!!

This works! Left it in the black and gray tanks and went away for the weekend. Sensors back to functioning properly in the black tank. They worked in the gray tank anyway but figured it wouldn’t hurt to give it a rinse too. Will definitely use this again!

The best out there

We have tried other Toilet treatments and found that this one is the best we really like the violet. It smells great cleans your tank out very well as well. Love it.
