Our top pick, the RMR-86 Mold & Mildew Stain Remover Spray, takes care of stubborn stains and odors without scrubbing.  Here are the best mildew removers on the market.  The RMR-86 Instant Mold Stain & Mildew Stain Remover spray is our best overall pick because it meets all of our criteria: a mildew remover that can tackle almost every surface, is budget-friendly, and works quickly. Not only can it remove stains in just 15 seconds, but it does so without any scrubbing, sanding, or brushing, so it’s incredibly easy to use. Because this spray uses the same active ingredient as bleach (sodium hypochlorite), we recommend wearing protective materials, like gloves and a face mask, when spraying this product in a poorly ventilated area. As effective as this spray is, it’s also not safe to use around children or pets, so be sure to keep them out of the area that you are cleaning. You’ll want to thoroughly wipe off and rinse any area that you’ve sprayed with this product after it’s lifted the stains. Keep in mind that some product may splash back on your clothing, so wear clothes that you don’t mind messing up, in case of a bleach stain. This spray works on most surfaces, including wood, concrete, and tile, and it can be used both indoors and outdoors. It also promises to be five times stronger than other products, so it’s a great, go-to product. We think this mildew spray is a great choice for anyone who has several heavy-duty cleaning projects around the house. Just be sure to use caution while spraying. Price at time of publish: $19 This formula is meant to be used on tile only, making it a solid pick for getting your bathroom like new, but not the other rooms of your home.

Price at time of publish: $23 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.

Cleaning Process

Depending on what you’re trying to use the mildew remover for, you may want to check out the process. Is it a spray-and wipe or scrub out? Do you need several coats or just one? Indoor or outdoor mildew remover? These are good questions to investigate before you purchase.

Some cleaners make sense for indoor use and some are stronger and are better used outside. Check your products before purchasing and test a small area before applying to the entirety of your space. It’s also a good idea to look at the differences between materials (stone, wood, tile, etc.) and pick based on the surface that needs cleaning.
