Puri Sol?
We have had Malibu Molly for around nine months and after we have been using it this long, we decided that we needed to clean the fresh water tank. Many vanlifers say they never drink water from their onboard water tank and so maybe they need to do this less cleaning. We do drink from ours, although we boil it first. Reggie drinks water from the tap. We also carry bottled water in 5 litre containers. Often filling empty ones from the mains water at home. Water in southern England is potable! 😉 So to cleaning. We usually do it using Puriclean in powder form mixed into a jug. This time we are using Puri Sol in liquid form. It's easier to deploy into the fresh water tank through the large red screw top. The instructions say three caps full per twenty five litres of water. That equated to 33ml. With a hundred litre tank it's twelve caps. Easier to measure in a jug and pour in the tank. It's supposed to be in there for around 8 hours. After I put it in around 6pm on Friday...
