One word of warning though... CANNOT USE BLEACH in black water tank with this method.. Bleach and Ammonia == Bad JuJu!!!!
So, recipe time.
Mix in 1 gallon jug
- 1 Cup Borateem (Borax)
- 1/2 Cup PineSol
- 1/2 Cup Ammonia
- Fill remaining with water
Again, CANNOT USE BLEACH. Shouldn't use bleach anyways in the black water, but in this case it is imperative otherwise things have a good potential to go BOOM, and BOOM is bad in this case...
Caveat with this type of talk. Everyone has their own preference on what to use and what's best to use so please keep that in mind.
Always use RV safe toilet paper that's passed the Toilet Paper Test
