In blog below, I griped a bit about cold water. In fact, the water from the tap and shower was cold, and salty. And a cold salty shower, after a cold salty dive, leaves you kind of cold, and salty.
But a bit of engineering gave us a warm (if salty) rinse! Our drinking water was all bottled, and we went through a lot of it. By refilling the empty bottles with cold salty water and leaving them in our "Solar Energy Collection Center" (eg, on some black rocks), we ended up with HOT salty water! A wonderful rinse.
Did have freshwater rinse a couple of days... When it rained, we stood under the run-off from the roof. Freezing, but fresh!
