I have not commented in a long while, but I read daily and sure learn a LOT from all of you. Thanks.
If you are traveling, and moving the RV every day or three, just drop one or two of those laundry packets in the toilet with 5-10 gallons of water or what is there. The motion of things while on the move, always has my indicators clean every time.
On the other hand, this sitting hooked up for 3+ months in Florida sure causes a "stone mountain" to need the attention of my "stir stick" weekly.
Oh well, then there is this weather vs. that weather. I will keep stirring.
