This is very odd. Each of the past five times we have gone to the boat there is hand soap spilled in the head. We have one of those standard plastic pump-type containers of hand soap in a teak holder. Now when we go to the boat there is a big gob of soap on the sole of the head just below the soap holder. My theory is that the recent warm water is adding pressure and "pumping" out soap. I have never seen this before. Ever happen to you??
