Why Use Gtechniq Marine Rust Stain Remover?
Rust Stain Remover is an aquatic-safe stain remover designed to dissolve rust, mineral deposits, and metal contamination from marine surfaces. It works on gel coat, fiberglass, and painted surfaces without the elbow grease that most rust removal products require.
Our formula reacts with ferrous particles on contact, turning purple as it breaks down stubborn rust stains. It is safe for coated and uncoated surfaces, and it removes rust stains from your boat without damaging the finish underneath. For any boat owner dealing with rust streaks from stainless steel hardware, anchor chain marks, or other metal contamination, this rust stain remover delivers fast stain removal with minimal effort.

I had these little rust spots on the back swim deck of my boat, and a section of decking at our floating house that I had cut some metal and didn’t think to remove the small metal things, and this product worked great for removing boat. I’d highly recommend this product for removing rust stains on multiple surface types.
