If you try to keep your bilges clean, you’ll find it much easier to spot leaks and fix problems, not to mention getting rid of that distinctive bilge smell. Try to avoid brushing crumbs into the bilges. Make sure the limber goles through bulkheads are clear and that water has a clear run from high spots down to any sumps for the pumps. A clean-out with washing up liquid and fresh water once a year will help keep everything clean and fresh.
