Cola soda in holding tanks?
I was told to put a couple 2 liter bottles of cola in black tank to clean and freshen it. Anyone done this? Also gray tank. And it's supposed to clean light sensors. Hard on seals?

TSP (tri-sodium phosphate), available at home improvement stores, probably would clean things better. It's the stuff they took out of detergents and dishwasher powders a few decades ago, causing those cleaners to lose some effectiveness.
