Once you have cleaned up the top of the tape apply a little Super Glue. Once hardened the glue will help prevent future problems. Make sure you turn the sail over and check the other side. If you are going to have us wash your sails do not use tape to mark problem areas, just take good notes. Cleaning Washing your sails before they are put away for the winter is a good idea.
Salt crystals are abrasive and corrosive.
Salt also attracts moisture and this can exacerbate existing mildew problems. On spinnakers the added weight of the moisture absorbed by the nylon can hamper light air performance. Our washing process is done by hand using warm water, a quality laundry detergent, and a non-chlorine bleach. We use hot water in a pressure spray to rinse. We wash in small batches of about twelve sails at a time.
