Sea It - Boat Wash

Have recently started to use Sea it boat wash on my boat.
After using many other brands of boat wash,I found Sea it the BEST and easiest product to use.
Removes all Salt and grits from my boat trailer and motor.
Sea it product leaves a nice and clean shine and no more water streaks.
I am a very fussy boat owner when it
comes to cleaning the boat after big
days of use.
Since I have started using Sea It boat wash I have also noticed that I don't have to spend lots of time washing the boat and this product does make my life easier.


Good to see them using copper parts. I’ve used others and they’ve just broken.
