Anyone have the same problem I have; small amount of green growth on the jib? I am able to easily wash off the green from the lower part (small strip along the foot) with a brush and water while still on the boat but most likely need to remove the jib to reach the upper spot.
Sounds like mold to me. I'd contact a sail loft (or sail cloth manufacturer) and ask what could be used that won't damage the fabric. Chlorine bleach will kill the mold but will probably be harmful to the dacron.
<i>Most sails will eventually end up with mildew stains. The most common chemical used to remove mildew is sodium hypochlorite— commonly known as bleach. Most mildew disappears quickly when bleach is applied—if doesn’t, the stain probably will not come off. A thorough rinsing is needed after applying bleach. Note: Bleach will not affect polyester (Dacron), Spectra, or Vectran fabrics. DO NOT use bleach on nylon, aramids (such as Kevlar or Twaron), or Technora. Bleach will destroy these fabrics.</i>
We have used a diluted bleach solution to get rid of troublesome stains on our sails. Be sure to rinse thoroughly.
I have used "Simple Green" and water. It is biodegradeable I think and doesn't damage the fabric. The green mildew is very common in coastal areas of South Florida.
I used Oxygenated bleach. You can buy it by the gallon at your regular grocery store, or use OxyClean same stuff. I use about 1 cup per 4 gallons in luke warm water in a bassin. Let soak overnight and rinse throughly. On stuborn area you can try using 50/50 solution with a brush. My 110% jib looked aweful then new using this procedure. Mold was in the seams and stiching.
I recently did the same on a spinnaker I was given. It has a mold stains all over and smelt aweful. Came out looking almost new and smells super. If you google "oxygenated bleach cleaning sails" you will find many recommendations.

My jib was pretty bad, too. I took it down and scrubbed with a medium brush and WestMarine biodegradable boat wash, rinsing well. It looks a lot better, but with mildew will probably never look perfectly new again. I hope the boat wash is gentle enough not to damage dacron...
