Hi, everybody. Andy here with etrailer.com. Let's take a brief look together at this Odorlos Treatment for RV and marine holding tanks. This six pound tub of non-toxic biodegradable treatments are gonna prevent odors and clogs by breaking down the waste in your black water tank or gray water tank. And this is going to be great for use on your RV or boat, and it can also be used in your septic tanks. This scent-free nitrate formula is going to do a great job of eliminating odors instead of masking them.
It is formaldehyde-free. And the good news is this is going to remain effective even in extreme temperatures. So four ounces are gonna treat a four gallon tank, and it is recommended for treating your tanks before camping or first use of your toilets. And the resealable tub is going to make this great for easy storage and easy transport. Well, I think that's gonna wrap up our real quick look today.
I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me.

This is an excellent product. IT WORKS!!!! 5 stars Service of order gets a big "F" for failure. The bucket of Oderless was packed UPSIDE down ,in the box and a considerable amount of it was spilled out all over the packing paper and box. can you send a partial refill, free, we've used this stuff for years. Thanks for any help with this.
This is the best tank treatment I've found Etrailer is the best vendor!
works as advertised
I've tried the digester product; but, I think this works better to control odor.
First time to use this product. Will have to see how it does. Received it in a timely manner and all intact.
We do really like the product as we are using our trailer to live in while building our house.
I do like the product very much. It does a good job for our application.
I have recommended it to a lot of other RV’ers in our travels.
Etrailer has the best/quickest order fulfillment and prices of all of the rv parts and supplies sources - bar none.
If you do not believe me then select the items and place them in the cart of a competing source to see the total and expected delivery times.
Etrailer beats them all, especially in order delivery speed - simply outstanding!
None of this bs about slow delivery or out of stock items like, "the warehouse has your order now," or, "the warehouse is completing/packing your order, or, "it will be back in stock shortly."
Thank you for this wonderful product , had fewer trips last season than we originally planned , but this treatment was easy to use , as you stated No strong odor, and kept our septic clean and functional. After last trip , dumped tanks and retreated prior to coming home , trailer has been stored in our front yard since , very happy we did a “ end of season treatment “ as had family sleeping in there for Thanksgiving, still functional, and remains clean .
Thanks again for a fine product, looking forward to upcoming trips this year (2023) .
I almost forgot about etrailer when getting ready to order. I hate using [online] and I remembered etrailer and it was cheaper and showed up on time.
I will continue and hope other people will also.
Thank you
This is the best product I've found for the portable potty in our 24' boat. Easy to use and comes in a compact package, which is great given the limited storage space on a boat. The price from etrailer was very competitive and the package arrived on schedule and in great shape. Great shopping experience. I'm a very satisfied customer.
Worked fine and did not see any major difference to other black tank treatments for my travel trailer, therefore average rating given.
EXCELLENT PRODUCT!!!!!!! .....BEEN USING IT FOR 5 YEARS ON MY HOUSEBOAT AND HAVE NEVER HAD A FOUL SMELL FROM MY TOILET HOLDING TANKS.....
Been using the product for years. Very good. Definitely recommend this product.
Best product I've ever used for black tanks. Great price as well
Quick response and delivery! Thank you!
Always been pleased with odorless for boat holding tank. Lives up to its name if added once per week.
Product arrived as advertised. Best price around! Very happy with my purchase; would buy from etrailer again.
Always works. No smells.
I have ordered from this company several things and I’ve never been let down I’ve always been very satisfied with the customer service and their products thank you
I suppose it does what it's supposed to. I'm not really trying hard to inspect the finished result, if you know what I mean.

It’s certainly a good buy, you get many tank treatments per tub. While the black water doesn’t smell like a bouquet of roses, it does take the edge off and liquifies the solids. I haven’t found a better tank treatment product but would be willing to try another if it’s more effective and priced competitively.
