Once it has cured completely, TotalBoat Halcyon varnish is very easy to clean and maintain. To maintain the surface, do not use cleaners that are abrasive, as these may ruin the varnish finish. It's okay to use mild detergent soaps diluted with water, such as TotalBoat Boat Soap, Murphy's Oil Soap®, Simple Green®; Pledge® and Windex® will also work. To avoid streaking or scratching the surface, use a soft cloth, such as a microfiber towel. Bleach and other heavy-duty chemical cleaning products should be diluted heavily with water, and rinsed off immediately after use.
