I have done this several times now... and tried various methods. From my experience this is what works best....

Machine wash with mild detergent.... I would never use any amount of bleach... I find that the mildew washes out with just the mild detergent...

I recommend only using 303 Fabric Treatment to treat the canvas..... I have tried other products like Starbrite Fabric Treatment and been less then thrilled with the results.... I found black staining after a summer of use, when I treated my canvas with the starbrite product. Admittedly all the staining washed out, but I have never experienced this when using the 303 formulation.

I will be taking my mooring cover to the laundry Mat later this summer and buying a gallon of 303 to treat it... It might be 10 dollars more then the starbrite product but my experience shows me that it is worth it....
