TotalBoat Halcyon varnish is a very low-maintenance product once it has fully cured. Though Halcyon is extremely chemically resistant, do not use heavy-duty or abrasive cleaners, as these may risk harming the finish of the varnish. Products ranging from boat soap, Simple Green®, Windex®, Pledge®, Murphy's Oil Soap®, or other mild detergent soaps that are diluted with water are also okay. Use a soft cloth, such as terrycloth or a microfiber cloth, to avoid scratching the surface or leaving streaks. Bleach and other heavy-duty chemical cleaning products should be very heavily diluted with water, and rinsed off immediately after cleaning.
