Nothing but this worked!!!
Fighting mildew stains is a loosing battle with toddlers in hot, humid Georgia. I have tried everything to get mildew out of our porch cushions. I know it says not use on fabric, but I figured it was worth a try since my cushions were so disgusting and I was going to replace them. This product works great on sunbrella fabric. Still waiting for the cushions to dry, but they were covered in black spots and now they look like new!!!
