Care information

While biothane is durable, our hardware can take a beating. Please limit exposure to harsh elements such as salt water to ensure a long life for your gear.

To clean your products, a little soap and water should do the trick. Stubborn stains should come off with a little rubbing alcohol.

Brass hardware may tarnish over time and can be brought back to life with ketchup or other brass polishers.
