A safe, non-toxic, and biodegradable marine growth remover. Specifically formulated to meet an industry wide need for a fast, safe, and cost effective alternative to mechanical cleaning of water cooled equipment. Can safely be recirculated through sea water cooling systems, dissolving barnacles, zebra mussels, calcium, rust, lime and all other mineral deposits. Contains a mixture of buffered-acids and special ingredients to quickly remove barnacles and clean rust, oil stains and algae. You've never seen anything like this! Barnacles literally begin to fall off the hull of the boat! Not your average boat bottom cleaner. Requires very little scrubbing. Will not harm fiberglass or gel coat.
