Sail Washing Day

I was bothered to discover that I had some small amounts of black mildew on my sail.  Likely caused by having splashed some sail water onto the sail the previous summer then storing it with boom/yard bundle under the covered but outdoor deck roof over the winter.  I read that soaking overnight  in a dilute bleach solution and then thoroughly rinsing might do the trick.  It certainly did.  

Looks like new again!
