Dealing with Dirty Sails

Among the many chores we’ve got ahead of us this winter, removing, and storing sails is one of them. This is also a good time to clean the sails.
We published a PS Advisor on the topic of cleaning sails in the April 2002 issue. Here’s a recap of that report and other articles we’ve done in the past.
You can clean most sails yourself, but be sure to set aside enough time. You also will need a large work area.
Be aware that some sailcloth materials (Kevlar and nylon in particular) are sensitive to certain substances—chlorine bleach and acetone, to name those most damaging. While Dacron holds up to mild doses of bleach, spinnakers and light-air sails made of nylon are particularly vulnerable. If you expose Kevlar or nylon to bleach—say you decide to rinse the sails in a swimming pool—they can lose up to 90 percent of their original strength.
For washing your sails, most sailmakers recommend using mild soap and water, and avoiding anything abrasive. Use a soft brush, if necessary, to loosen dirt. For dirt or stains that are more deeply embedded, you may need to soak the sail, so you'll have to locate some kind of large container, depending upon the size of the soiled area. (This is the time to requisition your kids' inflatable swimming pool.)
For mildew, some sailmakers advise simple household bleach, a 5.25-percent solution of sodium hypochlorite. We'd use a highly diluted blend first. Be sure to rinse thoroughly. We had mixed results with various mildew removers on sails in our 2009 test of mildew removers.
When you've finished cleaning, always rinse the sail liberally with fresh water. And, if you hang your sails to dry, do so at a time when it's not windy. If a sail is left to flog or flutter, you can do more harm than good. Remember, sails are composed of fibers, and the more back and forth bending those fibers have to endure, the more quickly they'll lose their strength.
You'll find additional information about the care and cleaning of sails on the North Sails website. In the New England area, you can contact the sailmakers at Hathaway, Reiser, & Raymond in Stamford, Conn., a sail loft specializes in the cleaning and reconditioning of sails. Readers elsewhere (Midwest, Mid-Atlantic, Gulf Coast, West Coast, and Pacific Northwest) can contact almost any large sail loft with a service department as most have arrangements with specialty cleaning services.
