Sea
water with a soft brush works quite well but the the trick is doing it every day as in every
single day! For anything else the trick is to use a system that can be repeated easily. The great looking finishes take weeks to remove and begin again. They all need to start over some time.
I'm pretty much convinced that the time required in the long term is the same. Nothing beats the destructive
power of UV light. The
deck hand is still cursed for the time being.
