    I would try a product called "Wet & Forget Outdoor." I had read a lot of good things about it and several months ago we tried it on the vinyl siding on our daughter's house, and our concrete patio. The north side of her house was covered with green algae and our patio had black and yellow algae. In the past, the algae was always quick to come back after just pressure washing. However, there is absolutely no sign of algae since we used the Wet & Forget. I'm very pleased with the results. We bought it at Home Depot. This link says it can also be used safely on outdoor cushions.

      @P.j. C I forgot to mention (but if you followed the link you probably read) that you don't even have to scrub the mildew with Wet & Forget. You just spray it on and it "does its thing" all by itself and keeps working with the help of wind and rain for up to a year! It's pretty amazing stuff! After trying it and seeing how well it works at keeping the mildew/mold/algae at bay, I'm not wasting my time or money on anything else in the future!

    White vinegar kills mold and won't discolor most fabrics.

    I have never found anything that takes out mildew stain!

    I would test a small area with a Clorox mixture. Clorox is the only thing that got rid of the mildew on my outdoor curtains. Since the fabric is sunbrella, the color should be tough enough to take the harshness of the Clorox. Whatever you do, once the mildew has been taken care of you must isolate the cause or you might have the same problem all over again. Good luck.

    Mix dawn Dish washing liquid, Baking soda and Hydrogen peroxide and put in a spray bottle. Let it soak in for a couple of minutes. Use a sponge or old worn out wash cloth and wipe dry. You can use cushions very soon after cleaning, unlike Clorox that might still be wet and will ruin your clothing if it is not dry enough.

    It looks like that black mold that gets on sidewalks or anything left out in the sunny weather with rain occasionally. Use Clorox in a spray bottle so you can control it better and spray it on the location but don't leave it - just watch it eat up the mold and rinse it off with a hose or a towel filled with water. Then buy yourself some chair covers (and depending on your locale), I'd throw some moth balls under the cover to keep out any animals that might want to nest there when the covers are on.

    The product called Totally Awesome. Our Kroger carries it as well as Rite Aid. It's all of $1.00 and I have to have 2 in the closet at all times! It's wonderful. I plan to use it on my lawn swing that has the mold/mildew issue next week. Test your fabric, but it should be fine. It's strong stuff, but works on virtually anything except paint! I also use Resolve religiously on carpet stains with great success.
