Keeping your boat looking its best is something we all should do, not just for the aesthetics but also because by doing so we keep everything in the best possible condition. Salt-Away is an incredible product, and when used in conjunction with this mixer unit it gets even better! The mixing unit is a required part of the delivery system for many Salt-Away applications, like flushing your inboard, outboard or jet ski, and can also be used in conjunction with a pressure washer, by utilizing its male and female threaded end connections, and rigging it inline before the washer. The receptacle for your Salt-Away mixer is 177ml and it has a 3-position switch (off, rinse, Salt-Away). The Salt-Away mixer was used extensively throughout the testing and development, and mixes Salt-Away at a ratio of 512 parts of water to 1 part of Salt-Away, meaning your bottle of Salt-Away is going to go a long way!
