How do I remove this? Seasalt is pretty resistant to all solvents, acids, etc. Any one has a solution?
An acid, likely Mary Kateís on and off will work
Itís not salt
, itís I believe calcium carbonate.
Donít get it on you, it will burn, but itís specifically made to clean hulls, I have always used it to remove ďtea stainsĒ you get on the bow from tannic water.
