I'm going to be trying that tomorrow, and I'll let y'all know how it works.
I've just emptied my black tank for the first time since adding the 1 cup Borax, 1/2 cup liquid Tide, and a gallon of hot water.
I have also continued bagging toilet paper.
I've been traveling 4 days, have noticed no offensive odor, and everything emptied without issue this morning.
Much less water used to flush, no odor, seemed to work just fine.
