I have to confess, I wasn't entirely alone... 'er indoors, and M came along to help me.... and scrubbed their hands raw as well!
We intended to stay onboard tonight and continue the scrubbing tomorrow, but after today's efforts, we were cold, had loads of wet clothing, and frankly, had just plain had enough!
So, we came home.
The decks are about half done, so it'll be another trip shortly.
