Never rig on hard or abrasive surfaces.
Always rinse the sails in fresh water if possible.
Do not dry in direct sunlight, in fact try to avoid leaving sails in direct sunlight for prolonged periods.
Roll the sails from the top and ensure no creases in the material when rolling it.
Store in a dry place, and make sure the sail is dry. If the sail is still wet, then place it upright, so it can dry out.
