    FREQUENTLY ASKED QUESTIONS

    What makes Salt Shift products different from other cleaning solutions?

    Salt Shift products are 100% Australian-designed and specifically formulated to remove salt, grime, and corrosion from marine and outdoor equipment. Unlike generic cleaners, our solutions are biodegradable, non-toxic, and safe for all surfaces.

    Are your products safe to use on all surfaces?

    Yes! Our formulas are non-corrosive and safe for gel coat, fiberglass, aluminum, stainless steel, plastics, rubber, and painted surfaces. They effectively remove salt deposits without causing damage.

    Will Salt Shift strip wax or protective coatings?

    No! Our formulas are pH-balanced and designed to clean effectively without stripping wax, ceramic coatings, or protective sealants.

    Is it safe to use on my car?

    Yes, the Salt Shift wash is formulated to be safe for all vehicle surfaces, including paint, metal, and plastics. It’s tough on contaminants but gentle on coatings and finishes.

    Will Salt Shift wash prevent corrosion?

    Yes, regular use helps prevent corrosion by removing salt and contaminants that can damage metal surfaces.

    How much do I need to dilute Salt Shift before use?

    Salt Shift formulas are twice as concentrated as standard cleaners, so they should be diluted at a 20:1 ratio (20 parts water to 1 part Salt Shift).

    For foaming guns, simply fill the bottle with the correct dilution, and the gun will mix it automatically. For spray bottles, pre-dilute the solution before applying. This ensures maximum cleaning power while remaining cost-effective for long-term use.
