BCF has just about anything you could need, whether Boating, Camping or Fishing is your passion. Salt-Away 3.79L concentrate can be used for a multitude of things. It can be used as an engine flush, in both inboard and outboard engines, I/O and PWCs (jet skis), and as an exterior salt removal treatment on any surface where salt corrosion or build-up can be an issue. Mixed with fresh water, Salt Away washes away salt residue and, if not rinsed, will leave a protective coating on the surface to continue to protect and prevent corrosion and salt build-up. Items can even be submersed in a mixture of Salt-Away and freshwater, and while submerged will not corrode.
