Osborne's Barnacle Dissolver is a cleaning product developed for the DIY market that works to loosen and lift stubborn marine growth and barnacles from shafts, rudders, trim tabs, propellers and boat bottoms.
The organic salts used in this product are naturally occuring and are non-toxic, do not produce the choking burning fumes that acids will and are non-corrosive to skin.
When sprayed on barnacles and other hard marine deposits, Osborne's Barnacle Dissolver will foam as it starts dissolving and loosening them.
While this product is safe for use on fiberglass and painted surfaces - this product can react with other materials so care should be taken to test the product in a small and inconspicuous area before using over a large area.
DO NOT USE ON BARE ALUMINUM
