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

I first tried a vinegar-and-water mixture on our boat upholstery that had some pretty serious mildew staining, but it didn't make much of a difference. I then ordered another marine cleaner that also failed to remove the stains. That's when I tried this product, and wow—this stuff really works. I sprayed it on and let it sit for just a few minutes. I could already see the mildew stains starting to fade before I even touched them. I applied one more light coat and used a soft kitchen scrub brush to gently work over the remaining spots. The stains came right out, and the upholstery looks brand new. I honestly couldn't believe the difference. After wasting time and money on other cleaners, this was the first product that actually delivered the results I was hoping for. If you're fighting stubborn mildew stains on boat upholstery or other marine surfaces, I highly recommend giving this a try. It saved our seats and exceeded my expectations.

I used this on our outdoor white cushions, and I was honestly so impressed with how well it worked! It did a great job removing the mold and mildew stains and made the cushions look so much better. I was so happy with the results that I’ve already purchased it twice and have even recommended it to friends. When I find something that actually works, I tend to stick with it, and this is definitely one of those products. I’ll keep buying it and would definitely recommend it to anyone dealing with mold and mildew stains on outdoor cushions.

This product is great! Removed mildew stains from outdoor cushions with no scrubbing at all!

Works pretty good with some elbow grease. Doesn't get out some of the stains completely, but is a big help. Very unsatisfied with the bottle though. Mine showed some signs of leaking during transit and even after putting the sprayer on it will leak. Sucks to have over half the product leak considering its price point.

This works fabulous, it took mildew stains off our jet ski seats and had them looking brand new in just a few minutes. I did have to do a second application in a few spots but it removed most of it with a single use. It smells just like bleach but it did not fade out bright red and blue seats at all.

Must admit that I was skeptical about this product. Was almost ready to buy something that was.$22 then saw this. I sprayed it on my outdoor furniture cushions this morning. I waited about 30 minutes before I checked—I was so excited when I went outside and saw that the mold was completely gone, and I had not even rinsed the product off. I will definitely buy this again and highly recommend it.

The product itself is great. The shipping not so much, 1 of the bottles had opened up and spilled inside the shipping box. I think the box needs to labeled this side up.

Finally a cleaning product that works as advertised! Had a patch of mildew show up in my pop-up camper due to moisture getting inside. After a bit of research and reading reviews on this product I purchased and am so happy with the ease at which the problem was taken care off. Just spray it on, and let it sit till mildew is gone and wipe down afterwards. I did notice on the thinner canvas fabric covering the window, it may have weakened the waterproofing and will have to re-seal it, but the main heavy duty canvas was fine. Make your mildew messes easy and grab STAR BRITE!!!

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!

This product worked great on my camper. There was tons of “black” on it from the trees surrounding it. I sprayed this on and let it sit for 15 minutes then a quick rinse and it was clean!

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