Looking for advice regarding using a mildewcide on new canvas. Have been considering using a Zinc Napthalate known as Zinctox. I'm concerned that this material could attack the material.
Also, I'm confronted with removing mildew stains on older sails. Has anyone experienced problems using chlorine bleach (about 6% and 1/20) How long should the canvas be exposed to the bleach and will the bleach deteriorate the fabric?
