I just bought a DS II and the sails are structurally good other than two small holes in the jib. There are a few rust? stains, some mildew stains and the seams are cruddy. Before sending them off I thought I''d try cleaning them. Would the new "oxy" cleaners do any harm? I thought of soaking them in a tub with the stuff then hoisting them up a tree in the back yard and rinsing them with a hose. Any thoughts?
