    Best for Fabric: Star Brite Mold & Mildew Stain Remover

    You might not think of mildew popping up on fabric, but if you’ve got outdoor furniture that gets wet (or maybe even a boat with cushions), it’s possible. Unfortunately, it’s really hard to get rid of—unless you use a great mildew remover, like this Star Brite spray. It’ll remove mildew on contact without heavy scrubbing, and it’s easy to use. Simply spray it on your stain, scrub it in lightly, then rinse off once you see the stain has disappeared.

    Not only does this work on fabric, but it's also safe to use on rubber, fiberglass, plastic, tile, and more. It can tackle mildew stains on vinyl or canvas seats, tops, cushions, or bolsters. It won’t harm stitching, either, so it’s ideal for outdoor furniture, boats, or outdoor canopies. It can even clean tents after camping! If you’ve got a stubborn stain that just won’t quit, a second application will usually get the job done.

With this bundle, not only will you get a mildew stain remover (our pick for best overall), but you’ll also get a cleaner and disinfectant.
