Salt-Away Concentrate & Inline Mixing Unit Salt Away Concentrate Refill cuts through salt buildup and corrosion on wake and ski boat engines, hulls, and components as well as PWC's. This highly concentrated formula yields up to 480L of ready-to-use solution, delivering exceptional value for regular maintenance. The included inline mixing unit simplifies application by automatically proportioning concentrate with water during rinse cycles—no manual mixing required. After rinsing, it leaves a protective anti-corrosion film that shields metal, fibreglass, and painted surfaces. Safe for engine flush and wash cycles without damaging rubber seals or plastics. Non-toxic and biodegradable, it's engineered for marine environments where salt exposure demands reliable protection. Available in 946ml and 3.79L refill sizes to suit your boat's maintenance schedule.
