Time to give the sails a bit of a clean, anyone have some recommendations? What works, what doesn't?
From some reading around it sounds like bleach (30 Seconds) is a no no, as it will rot the stitching. The one recommendation I have seen a few times is Napisan. The process is to spread the sail on the lawn and wet it, sprinkle Napisan and rub in with a soft brush. Then roll the sail up and leave it for 12 to 24 Hrs and then thoroughly wash down and dry.
I thought of adding some laundry detergent just before the final wash down.
