Camco TST Blue Enzyme RV Toilet Treatment | Features a Biodegradable Septic Safe Formula, a Clean Scent, and is Ideal for RVing, Boating, and More | 64 oz (41506)

We've owned an rv for 6 years. Have tried tablets, liquids, and gel packs for tank treatment. Everytime we flushed the toilet it reaked. This is the first camping trip we did not smell anything!

We’ve found this to be excellent.Smell not offensiveExtremely easy to useThe only negative was the retail price. Now on Amazon it’s 1/3 the cost. (!)This’ll last us quite awhile but I’ll buy it again.

I used it in my rv black tanks to help clean them out

I use this every time I dump my black water holding tank and it lasts for about a month, even during hot Texas summers! Great product!

I use something else for my black tank, but I use this in my gray tank for my 5th wheel trailer. I always buy more when I run out... That should say something.I wish it was cheaper though.

Works better than the tablets and cheaper than in the store. Win win

First got the camper n had sewer flies. This product is the answer to making them GO AWAY.

Does its job well

I am okay with this product.

I have tried different products but I pretty much stick to this brand now it works well and is very reasonably priced I never have issues with smell and all solids seems to liquify quite well. I will keep using this product and would recommend to others.

Our favourite product to use for our rv toilet without using toxic chemicals. Nice smell. Good value

Havent noticed a huge difference in it helping but it does make it smell better.

Great product, seems to work well and easy to use
