STAR BRITE Professional-Grade Mildew & Mold Stain Remover + Cleaner - Instant Contact Stain Removal, Ideal for Marine & Outdoor Upholstery

I had given up hope on ever removing the mildew from my deck furniture and canvas cushions. Although our deck furniture was kept outside under a covered deck, most everything was still subjected to the fickle, moist Ohio summers. Add to that drippy popsicle messes, and a band of homeless cats that routinely took up residence on the cushions at night, and you can imagine how literally disgusting the furniture on our deck was by the end of the summer. The cushions had both spotty mildew and dirt. To note, the instructions specifically state that this product is not for use on fabric. I decided to ignore that, as it was this or buy new cushions. I absolutely cannot believe how well this stuff works. I used it on four different types of materials, with impressive results. I do have a few suggestions for use...wear protective eye wear and wear a filter mask. I went bonkers spraying this stuff on my porch swing, and almost passed out from the fumes. It smells worse than straight bleach. Use this outside, on a relatively windless day, or you'll feel the burn on your skin. I'm not really a safety freak, but I do think eyewear, long sleeves, a mask, and sturdy gloves are a must. Wear something you don't mind ruining. That being said, I tried my deck swing first. It is that weird plastic wood composite stuff that's supposed to last forever, but it's white, so it shows everything. I sprayed the entire swing, and waited about 10 minutes before rinsing with my garden hose. Most of the spotty black gunk was gone, but I wasn't truly happy until I used a second application. The swing looks brand new again. Then I moved onto the cushions. I opted against testing an inconspicuous spot, and went to town. This stuff removed not only the mildew, but also the dirt from the cats. A few spots I had to treat twice, but the cushions look amazing. The cushions are a light teal color, so they show everything. I also used it on the multi colored patterned pillows- no problems with the colors bleeding or running. Also just hosed these off and left them in the sun to dry. Honestly I though for sure this would bleach the colors, or leave white spots all over, but that didn't happened. I moved on to the plastic deck box and outdoor garbage cans. Same awesome results, and no scrubbing required. So far, this has been the best cleaning day of my life. I live with my husband and gaggle of grimy active children, so to have something this clean is nothing short of a miracle. The last place I tried this product was on the greenish algae spots on my house siding. I had to use a stiff bristled brush, and a little elbow grease, to get everything, but it wasn't terribly difficult. I probably didn't need the brush, but I didn't want to spray this stuff above my head, and experience the rain down, so I applied some on the brush and scrubbed that way. I feel like this product has a multitude of uses. I can't wait to tackle the outdoor umbrellas next. I bought the gallon size, and used about half of it to treat 6 cushions and pillows for our deck set, 4 decorative pillows, a deck box and cushion, porch swing, two garbage cans, and about , 6x6 foot area of algae covered siding. A little goes a long way, but if the area you are treating is heavily soiled, plan on two applications. Also, if you really like your stuff, and you're not completely desperate, I would test any fabric for colorfastness prior to use.

Amazing stuff!! Cleaned all the mildew stains off my boat seats, tried many other products this is the only one that cleaned them and made it look like new.

This stuff works great. Cleans mold off of just about anything. Has a bleach smell but I can get over that since it works so well. Didn’t leak during shipping and was a great salute for the money.

Works amazingly! Smells just like Clorox spray, so may be cheaper just getting that.

Excellent product I buy it every year to remove the mildew and stains before I waterproof the boat cover

I bought this for a canvas tote that was partly under an ice chest. It was covered in Mildew and after a solid washing that did nothing to fix the issue we sprayed this on it. The mildew and the discoloration vanished. The canvas tote looks like new, as it was new, and then we tried it on other mildew stained items. Our outdoor oil painted shed doors have mildew on then every summer. This completely cleaned them and for the first time in years we don't have to repaint the doors. This also works on our outdoor Solo Stove pit plastic cover. It has a strong smell of bleach but there must be something else in it as it seems to work perfectly where bleach does not without destroying canvas. Highly recommend even if the price seems quite high.

Works great on my boat vinyl. Followed instructions and it works great/

I had mildew on outdoor cushions this product worked great on them. Spray & go. I couldn’t believe how it got it out & was so easy to use. Definitely recommend this & will definitely purchase again. Thanks

I was gifted a tent trailer that had been neglected for a few years and had heavy mildew all over the interior. Worried about the fabric, we tried all kinds of more "natural"/less harsh remedies; lemon, vinegar, hydrogen peroxide, etc. They lightened the spots a bit, but they were still very noticeable. I then bought some non-bleach mold/mildew killer/stain remover from the local home renovation store. Same thing, possibly even less effective. I read about this product on Reddit and a few other places online and decided I didn't have anything to lose - replacing the vinyl fabric on my 2012 trailer would cost $2500+... The results were phenomenal! I protected the trim pieces and metal sliders with some old cloths, sprayed it on quite liberally with a dollar store spray bottle, waited about 30 minutes and wiped it off with clean water and a sponge. The spots were either gone entirely, or almost gone! Some spots required two or 3 applications, I probably could've helped the product along by scrubbing first or something, but at this point I was past caring and wasn't really hoping for much. Long term, I don't know if this will degrade the fabric, but as I said - it was this or the trash! It does have a very strong odour and strict warnings about eyes, breathing, and skin protection - believe it! Get as much ventilation as you can, wear old clothes (it dripped on my shirt and took the colour out), protect your eyes and wear gloves. tl;dr - It works and smells strong (like bleach). Not 100% sure it's entirely safe on the vinyl fabric since I didn't ask trailer manufacturer. Ps. Pictures are from about 2 weeks apart, that's why the lighting is different, but I promise it's the same trailer.

I really didn’t think the mildew stains would come off our boat when we removed the covers in the spring, but amazingly with a little bit of scrubbing with a sponge and rag, it did come off! 9O% off, and almost back to original condition. Will routinely use this every year at beginning of cottage season. Also works great in the shower on mildew and mold. Would buy again.

Ce produit est fantastique! Il a enlevé tout les taches de moisi sur mes sièges de ponton! Merveilleux!

Worked mint in my boat seats

Enlève les tâches de moisissures sur les toiles de tente roulotte... Juste appliquer en spray et laisser agir. Très bon résultats.
