## Overview

Star brite Step 1: Stain Remover is a professional-strength, concentrated cleaner that quickly eliminates mold and mildew stains on contact using a buffered-bleach triple-action formula. Safe for outdoor fabrics like Sunbrella and a wide range of surfaces including vinyl, fiberglass, wood, and concrete, it delivers superior cleaning without harming stitching or threads. Ideal for boats, patios, RVs, and commercial use, this USA-made solution transforms grimy outdoor spaces with minimal effort.

## Description

"Mildew Stain Remover quickly removes unsightly mildew stains and mold stains from fiberglass, vinyl, plastic or painted surfaces. It begins working on contact. The special buffered formula will not harm vinyl upholstery or threads. It is a better alternative to using regular bleach and contains chelating agents and surfactants to clean better than bleach alone. It can be used on the boat, around the home, on patio furniture, campers, cushions, or wherever mold stains and mildew stains are a problem. Just spray or wipe Star brite Mildew Stain Remover on most canvas T-tops, boat seats, boat covers, bolsters, vinyl cushions, vinyl chairs, bimini tops, tile, grout, shower stalls, shower curtain liners, shower mats, bathrooms, awnings, siding, wood and more. Do not rinse until stains disappear. Most stains disappear in 15 seconds to 30 seconds. Stubborn stains may require a second application and light scrubbing. Rinse well after use. For use on outdoor acrylic fabrics such as Sunbrella brand; not recommended for use on indoor fabrics or clothing; test for colorfastness in an inconspicuous area before proceeding with overall cleaning. PRO TIP: Bleach-based stain removers do not kill mold and mildew, they only remove the stains. For long term mold stain and mildew stain control, follow with a Chlorine Dioxide-based (ClO2) biocide spray like PERFORMACIDE Mold & Mildew Eliminator. This EPA registered mold, mildew, slime, and fungus killer will not remove stains, so use both products in sequence for optimal results. ClO2 also removes mildew smells and musty odors. PERFORMACIDE Mold & Mildew Eliminator does not require rinsing and leaves no harmful residue. FOR LONG TERM, PROFESSIONAL RESULTS, FOLLOW THESE STEPS: STEP 1: Remove the stains with MILDEW STAIN REMOVER STEP 2: Kill the organism with PERFORMACIDE MOLD & MILDEW ELIMINATOR STEP 3: Prevent future mildew stains with Star brite Mildew Stain Blocker (optional) "

Review: Life changing - 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.
Review: Cleaned up moldy vinyl seats on my boat. - Purchase this to clean some black mold that was growing on my boats vinyl seats from being underneath of a cover that had torn where water had gotten inside underneath of the cover.

### ⭐⭐⭐⭐⭐ Fantastic
*by C***. on December 4, 2025*

Used this on our boats seats and it worked beautifully. Sprayed it on and let it sit for a few as the instructions said and the mildew stains just disappeared. Used a little scrubbing on some areas but it mostly came off after letting it sit. Rinsed and the seats looked nearly good as new. It also worked well on the hull.
