Some shipyards are turning to vodka to flush systems and make sure your boat is ready for winter.

What are they using to clean your systems for winter? It might not be what you think... Some shipyards have taken to using vodka to decommission boats with freshwater systems. The practice has existed for some time, but it was only recently that it started gaining popularity among boatyards for their higher end customers.

The concept is that the vodka will help identify places in the system where water remains. First the freshwater system is drained entirely, then vodka with food coloring is flushed through to penetrate any spots where water might remain. After the water is cleared, any vodka that remains will evaporate leaving no taste and no trace next season.
