If the sails are deeply ingrained with mould then you may wish to go for the chemical clean organised by most sail lofts but it is a very expensive process.
A neutral detergent, light brushing, and lots of rinsing water is perfect for surface dirt and low level stains.
For messy stains that didn't respond to that, I've used the services of Vacuwash Australia
(Sail Cleaning and Protection TechnologyVacuwash Australia - Home
). As the name suggests, Vacuwash uses a vacuum wash process followed by applying SailKote.
, but not what I call very expensive.
I was very happy with the personal service
(including advice on shipping
to and from Vacuwash), and the result.
Vacuwash started in the US and still operates there.
