Star Brite Bio-Origin Marine Antifreeze is a pre-mixed, glycerol-based winterising fluid for boats laid up over the cold months. Because it is ready to use, you flush and drain the system first, then fill the lines, pumps, toilets and engine circuits as the instructions describe. The ethanol-free formula also lubricates seals, valves and pumps while the boat sits in storage. Frost can split pipes and crack pump housings on a boat left afloat or ashore, so winter protection matters for anyone sailing in Ireland. Keep surplus out of drains and watercourses, and take it to a chemical waste depot instead.
