RTB 780 Toilet Treatment

It works
From Joseph Bova of Ashland, Oregon on 7/21/2019.

I've used this stuff a number of times on river trips longer than 4 days. It reduces odors significantly, especially if people pee in the river first and keep urine out of the groover. It is also very effective on preventing gas build-up in the full groovers that will be riding-out the last days of the trip without being opened.

Best Groover Stuff
From HtotheJ of Denver, Colorado on 7/9/2016.

Been using this stuff for many years in my groovers. one and the beginning of trip to start and if you get half way full, pop in another one. Works great and never had a problem at cleanout. Get some and make your life easier :)
